Nikitas Papasimakis, Tim Raybould, Vassili A. Fedotov, Din Ping Tsai, Ian Youngs, and Nikolay I. Zheludev

Phys. Rev. B 97, 201409(R) (2018) - Published 23 May, 2018

A proposed scheme for generating torus-shaped light pulses called flying doughnuts utilizes a metamaterial “sprinkled” with tiny resonators in a concentric ring pattern.

Giant nonlinear interaction between two optical beams via a quantum dot embedded in a photonic wire

H. A. Nguyen, T. Grange, B. Reznychenko, I. Yeo, P.-L. de Assis, D. Tumanov, F. Fratini, N. S. Malik, E. Dupuy, N. Gregersen, A. Auffèves, J.-M. Gérard, J. Claudon, and J.-Ph. Poizat

Phys. Rev. B 97, 201106(R) (2018) - Published 11 May, 2018

Optical nonlinearities usually occur at large intensities, but discrete transitions allow for giant nonlinearities operating at the single-photon level. Here, the authors demonstrate a two-mode giant nonlinearity with a single semiconductor quantum dot, embedded in a broadband photonic wire antenna. They exploit two detuned optical transitions associated with the exciton-biexciton quantum-dot level scheme. The reflection of one laser beam is controlled by the other beam with a threshold power as low as ten photons per exciton lifetime (1.6 nW). Such a two-color nonlinearity opens up appealing perspectives for the realization of integrated ultralow-power logical gates and optical quantum gates.

Candidate for a fully frustrated square lattice in a verdazyl-based salt

H. Yamaguchi, Y. Tamekuni, Y. Iwasaki, and Y. Hosokoshi

Phys. Rev. B 97, 201109(R) (2018) - Published 14 May, 2018

Frustrated spin systems prevent the formation of conventional magnetic order and can form an entangled spin state. A frustrated square lattice with only nearest-neighbor interactions is called a fully frustrated square lattice (FFSL) and expected to exhibit strong quantum fluctuations. Here, the authors present an experimental realization of an S=½ FFSL composed of a verdazyl-based salt. Ab initio calculations indicate the formation of an FFSL with competing ferro- and antiferromagnetic nearest-neighbor interactions. The magnetic behavior demonstrates that the system forms a quantum valence-bond solid state. This material provides a way to realize a variety of S=½ FFSLs through the molecular design method, proposed here.

Classification of symmetry-protected phases for interacting fermions in two dimensions

Meng Cheng, Zhen Bi, Yi-Zhuang You, and Zheng-Cheng Gu

Phys. Rev. B 97, 205109 (2018) - Published 9 May, 2018

The authors deal with the fundamental problem of a rigorous classification of quantum topological phases. Here, they extend to the realm of interacting fermions in two dimensions techniques, developed for bosons, whereby they introduce extrinsic defects carrying symmetry fluxes into the topological phase. The result is a complete classification of symmetry-protected topological phases of interacting fermions in two dimensions. In addition, the classification of interacting fermion systems with time-reversal symmetry is also developed. The advances, reported here, are immediately relevant for the selection of reliable candidates for topologically protected storage and communication.

Learning disordered topological phases by statistical recovery of symmetry

Nobuyuki Yoshioka, Yutaka Akagi, and Hosho Katsura

Phys. Rev. B 97, 205110 (2018) - Published 9 May, 2018

Understanding the phases of a model usually requires knowledge of their characteristic features, which are nonlocal in topologically ordered systems. Here, the authors reframe the phase classification problem in disordered topological superconductors as a data-driven task, motivated by the recent surge of interest in the application of machine-learning techniques including deep learning. It is demonstrated that an artificial neural network learns to extract the essence of the clean system and successfully distinguishes phases even under disorder by statistical recovery of translational symmetry.

Hall viscosity and geometric response in the Chern-Simons matrix model of the Laughlin states

Matthew F. Lapa and Taylor L. Hughes

Phys. Rev. B 97, 205122 (2018) - Published 17 May, 2018

The authors show here that geometric properties of Laughlin fractional quantum Hall states are accurately described by the Chern-Simons matrix model, a regularization of the noncommutative Chern-Simons theory description of these states. The noncommutative Chern-Simons theory itself is an example of an exotic noncommutative field theory: a quantum field theory on a space where the coordinates do not commute. The authors revisit these noncommutative theories and show that they capture the Hall viscosity of the Laughlin states, as well as other geometric properties of these states that are of current interest.

Tunable Majorana corner states in a two-dimensional second-order topological superconductor induced by magnetic fields

Xiaoyu Zhu

Phys. Rev. B 97, 205134 (2018) - Published 25 May, 2018

Starting from a minimal model of a time-reversal-invariant topological superconductor in two dimensions, the author shows that an in-plane magnetic field could drive the superconductor into a second-order topological phase, which features Majorana zero modes, bound at two of the four corners of the system. These Majorana corner states occur where edges with distinct topology intersect. Hence, the corner states are topologically protected. With variation of magnetic-field orientation, the nontrivial corner states would move along the boundary and reside on different corners.

Second-order topological insulators and superconductors with an order-two crystalline symmetry

Max Geier, Luka Trifunovic, Max Hoskam, and Piet W. Brouwer

Phys. Rev. B 97, 205135 (2018) - Published 25 May, 2018

While topological insulators have a gapped bulk band structure, they have gapless surface states. Recently, it was shown that the presence of additional crystalline symmetries can lead to topological phases that combine a gapped bulk spectrum with gapless states on edges or corners of the crystal. Such topological phases have been called “higher-order topological phases”. This article presents a complete classification of second-order topological insulators and superconductors with mirror, twofold-rotation, or inversion symmetry. The authors show that crystals with a mirror symmetry and a nontrivial bulk band structure either have gapless surfaces or gapless edges. On the other hand, there are crystals with twofold rotation or inversion symmetry with a nontrivial bulk topology but without surface or edge states.

Higher-order topological insulators and superconductors protected by inversion symmetry

Eslam Khalaf

Phys. Rev. B 97, 205136 (2018) - Published 25 May, 2018

Here, higher-order topological insulators and superconductors protected by inversion symmetry are investigated. These phases are characterized by gapped bulk and surface with gapless modes confined to hinges or corners of the sample. Such surface states can be understood as topological defects that are globally stabilized by inversion. They can be built using a layer construction that embeds a standard topological insulator/superconductor into a higher dimension by symmetrically adding to it copies of itself. Using this procedure, a complete classification of such states in any dimension is obtained and several examples for possible physical realizations are provided.

Quantum computing with Majorana fermion codes

Daniel Litinski and Felix von Oppen

Phys. Rev. B 97, 205404 (2018) - Published 2 May, 2018

Majorana-based qubits are candidates for qubits with long coherence times. Just like conventional qubits, these qubits require active error correction in order to run arbitrarily long quantum computations. Unlike conventional quits though, Majorana-based qubits can use not only qubit-based codes, but also Majorana fermion codes for error correction. Several proposals for Majorana-based quantum computing with and without error correction exist, each featuring individual strategies to implement a universal set of gates. This paper unites all these approaches in a general framework, in which a certain set of operations—Clifford gates—are implemented with zero time overhead.

Chemical and valence reconstruction at the surface of SmB6 revealed by means of resonant soft x-ray reflectometry

V. B. Zabolotnyy, K. Fürsich, R. J. Green, P. Lutz, K. Treiber, Chul-Hee Min, A. V. Dukhnenko, N. Y. Shitsevalova, V. B. Filipov, B. Y. Kang, B. K. Cho, R. Sutarto, Feizhou He, F. Reinert, D. S. Inosov, and V. Hinkov

Phys. Rev. B 97, 205416 (2018) - Published 14 May, 2018

SmB6 is a mixed-valence, strongly correlated Kondo insulator. Moreover, its band structure makes it a promising contender in the quest for one of the first systems with topologically nontrivial and correlated surface states. Despite the “topological protection”, surface layer reconstructions can fundamentally change the material’s properties, so that the topological state is expelled into the undisrupted bulk. Following previous indications, the authors combine resonant reflectivity, photoemission, and theory to uncover chemical and valence reconstruction and its dynamics, resulting in boron termination and Sm3+ subsurface dominance. This work reconciles earlier studies using more surface-sensitive techniques, such as photoemission and scanning tunneling spectroscopy.

Gauge invariance of excitonic linear and nonlinear optical response

Alireza Taghizadeh and T. G. Pedersen

Phys. Rev. B 97, 205432 (2018) - Published 18 May, 2018

Excitons strongly influence the optical response of low-dimensional materials. Here, the authors propose a practical framework for calculating the excitonic linear and nonlinear optical response of multiband semiconductors based on the perturbative density matrix within the mean-field approximation. Using this framework, the equivalence of four different approaches is demonstrated analytically and numerically, if the correct velocity gauge interaction is used. The four approaches stem from two choices of gauge and two ways of computing the response functions. The present formalism can readily be extended to generate gauge invariant responses for higher-order nonlinear processes.

Burek, Mian Zhang, Lue Wu, Jose L. Pacheco, John Abraham, Edward Bielejec, Mikhail D. Lukin, Mete Atatüre, and Marko Lončar

Phys. Rev. B 97, 205444 (2018) - Published 29 May, 2018

Here, the authors tune the color of light emitted by single-atom imperfections (silicon vacancy color centers) inside a diamond. Such tunable imperfections can be networked together to build a quantum internet, where information can be securely exchanged using the laws of quantum physics. One problem is that all the centers need to emit at precisely the same color or wavelength. The authors overcome this challenge by placing color centers inside a diamond nanostring. By adjusting the tension in the string, atoms are stretched inside the crystal and tune the center to emit photons of a desired wavelength. The tuning method involves bending the string with a force controlled handily with an electrical voltage. A symphony of such tunable diamond strings could serve as the backbone of a future quantum internet.

Phys. Rev. B 97, 205122 (2018) - Published 17 May, 2018

The authors show here that geometric properties of Laughlin fractional quantum Hall states are accurately described by the Chern-Simons matrix model, a regularization of the noncommutative Chern-Simons theory description of these states. The noncommutative Chern-Simons theory itself is an example of an exotic noncommutative field theory: a quantum field theory on a space where the coordinates do not commute. The authors revisit these noncommutative theories and show that they capture the Hall viscosity of the Laughlin states, as well as other geometric properties of these states that are of current interest.

Tunable Majorana corner states in a two-dimensional second-order topological superconductor induced by magnetic fields

Xiaoyu Zhu

Phys. Rev. B 97, 205134 (2018) - Published 25 May, 2018

Starting from a minimal model of a time-reversal-invariant topological superconductor in two dimensions, the author shows that an in-plane magnetic field could drive the superconductor into a second-order topological phase, which features Majorana zero modes, bound at two of the four corners of the system. These Majorana corner states occur where edges with distinct topology intersect. Hence, the corner states are topologically protected. With variation of magnetic-field orientation, the nontrivial corner states would move along the boundary and reside on different corners.

Second-order topological insulators and superconductors with an order-two crystalline symmetry

Max Geier, Luka Trifunovic, Max Hoskam, and Piet W. Brouwer

Phys. Rev. B 97, 205135 (2018) - Published 25 May, 2018

While topological insulators have a gapped bulk band structure, they have gapless surface states. Recently, it was shown that the presence of additional crystalline symmetries can lead to topological phases that combine a gapped bulk spectrum with gapless states on edges or corners of the crystal. Such topological phases have been called “higher-order topological phases”. This article presents a complete classification of second-order topological insulators and superconductors with mirror, twofold-rotation, or inversion symmetry. The authors show that crystals with a mirror symmetry and a nontrivial bulk band structure either have gapless surfaces or gapless edges. On the other hand, there are crystals with twofold rotation or inversion symmetry with a nontrivial bulk topology but without surface or edge states.

Higher-order topological insulators and superconductors protected by inversion symmetry

Eslam Khalaf

Phys. Rev. B 97, 205136 (2018) - Published 25 May, 2018

Here, higher-order topological insulators and superconductors protected by inversion symmetry are investigated. These phases are characterized by gapped bulk and surface with gapless modes confined to hinges or corners of the sample. Such surface states can be understood as topological defects that are globally stabilized by inversion. They can be built using a layer construction that embeds a standard topological insulator/superconductor into a higher dimension by symmetrically adding to it copies of itself. Using this procedure, a complete classification of such states in any dimension is obtained and several examples for possible physical realizations are provided.

Quantum computing with Majorana fermion codes

Phys. Rev. B 97, 205404 (2018) - Published 2 May, 2018

Majorana-based qubits are candidates for qubits with long coherence times. Just like conventional qubits, these qubits require active error correction in order to run arbitrarily long quantum computations. Unlike conventional quits though, Majorana-based qubits can use not only qubit-based codes, but also Majorana fermion codes for error correction. Several proposals for Majorana-based quantum computing with and without error correction exist, each featuring individual strategies to implement a universal set of gates. This paper unites all these approaches in a general framework, in which a certain set of operations—Clifford gates—are implemented with zero time overhead.

SmB6 is a mixed-valence, strongly correlated Kondo insulator. Moreover, its band structure makes it a promising contender in the quest for one of the first systems with topologically nontrivial and correlated surface states. Despite the “topological protection”, surface layer reconstructions can fundamentally change the material’s properties, so that the topological state is expelled into the undisrupted bulk. Following previous indications, the authors combine resonant reflectivity, photoemission, and theory to uncover chemical and valence reconstruction and its dynamics, resulting in boron termination and Sm3+ subsurface dominance. This work reconciles earlier studies using more surface-sensitive techniques, such as photoemission and scanning tunneling spectroscopy.

Excitons strongly influence the optical response of low-dimensional materials. Here, the authors propose a practical framework for calculating the excitonic linear and nonlinear optical response of multiband semiconductors based on the perturbative density matrix within the mean-field approximation. Using this framework, the equivalence of four different approaches is demonstrated analytically and numerically, if the correct velocity gauge interaction is used. The four approaches stem from two choices of gauge and two ways of computing the response functions. The present formalism can readily be extended to generate gauge invariant responses for higher-order nonlinear processes.

Here, the authors tune the color of light emitted by single-atom imperfections (silicon vacancy color centers) inside a diamond. Such tunable imperfections can be networked together to build a quantum internet, where information can be securely exchanged using the laws of quantum physics. One problem is that all the centers need to emit at precisely the same color or wavelength. The authors overcome this challenge by placing color centers inside a diamond nanostring. By adjusting the tension in the string, atoms are stretched inside the crystal and tune the center to emit photons of a desired wavelength. The tuning method involves bending the string with a force controlled handily with an electrical voltage. A symphony of such tunable diamond strings could serve as the backbone of a future quantum internet.
