Scandium-based point defect in AlN for quantum information processing

Kamil Czelej, Mark E. Turiansky, Sai Mu, and Chris G. Van de Walle

Phys. Rev. B 110, 125116 (2024) - Published 9 September, 2024

Point defects in wide-band-gap semiconductors are leading qubit candidates for realizing quantum information processing. The authors investigate here the electronic structure and magneto-optical properties of scandium-related point defects in AlN, a material widely used in electronics and optoelectronics. The positively charged scandium−nitrogen-vacancy complex, which has a singlet ground state, exhibits a spin polarization cycle similar to the ST1 center in diamond, with long coherence time resulting from an electron spin being transferred to a nuclear spin, and large optically detected magnetic resonance readout contrast. These properties render the center promising for use as a quantum memory.

Signatures of hidden octupolar order from nonlinear Hall effects

Sopheak Sorn and Adarsh S. Patri

Phys. Rev. B 110, 125127 (2024) - Published 11 September, 2024

Discovering long-range hidden orders is a long-standing challenge in the field of unconventional magnetism. Such type of order is elusive to conventional magnetic probes. Here, focusing on the archetypal ferro-octupolar ordering in metallic heavy-fermion compounds, the authors demonstrate through a combination of semiclassical transport and general symmetry analysis that nonlinear Hall transport is the dominant experimental signature.

Bipartite Sachdev-Ye models with Read-Saleur symmetries

J. Classen-Howes, P. Fendley, A. Pandey, and S. A. Parameswaran

Phys. Rev. B 110, 125140 (2024) - Published 19 September, 2024

The authors introduce and analyze a novel example of a nonlocal model that violates the eigenstate thermalization hypothesis via Hilbert space fragmentation. This fragmentation manifests itself through the presence of a highly degenerate null space. The commutant algebra responsible for the fragmentation is a subalgebra of the Read-Saleur commutant of Temperley-Lieb models. The model studied resembles the Sachdev-Ye model, and its low-energy correlators are analyzed using similar techniques. Perturbations leading to quantum many-body scarring in the model are also considered.

Topological quantum phase transitions driven by a displacement field in twisted MoTe2 bilayers

Prakash Sharma, Yang Peng, and D. N. Sheng

Phys. Rev. B 110, 125142 (2024) - Published 20 September, 2024

The Chern bands in twisted MoTe2 semiconductor bilayers host fascinating quantum effects, including the fractional quantum anomalous Hall (FQAH) state at a zero magnetic field. This study explores the stability of 1/3 and 2/3 FQAH states under intermediate values of an externally applied out-of-plane electric displacement field, where the single-particle band topology remains unchanged. By demonstrating the nontrivial effects of electric fields on partially filled topological bands, the authors map a rich topological quantum phase diagram as a function of twist angles and displacement fields.

Unconventional topological mixed-state transition and critical phase induced by self-dual coherent errors

Yu-Hsueh Chen and Tarun Grover

Phys. Rev. B 110, 125152 (2024) - Published 26 September, 2024

Topologically ordered phases host anyons that can condense, leading to a trivial gapped phase. Such a transition can be induced by coupling to an environment. This paper explores a scenario where the coupling between a topologically ordered phase and the environment maintains a self-duality symmetry that interchanges anyons with nontrivial mutual statistics. The authors find that this duality symmetry prevents anyon condensation and, further, for a range of the coupling strength, the topological phase is destroyed in favor of an exotic critical phase.

Terahertz and gigahertz magnetoratchets in graphene-based two-dimensional metamaterials

M. Hild, E. Mönch, L. E. Golub, I. A. Dmitriev, I. Yahniuk, K. Amann, J. Amann, J. Eroms, J. Wunderlich, D. Weiss, C. Consejo, C. Bray, K. Maussang, F. Teppe, J. Gumenjuk-Sichevska, K. Watanabe, T. Taniguchi, and S. D. Ganichev

Phys. Rev. B 110, 125303 (2024) - Published 13 September, 2024

Here, the authors study the ratchet effect – the conversion of alternating fields in the terahertz and gigahertz range into direct current – using a 2D metamaterial formed by monolayer graphene and a nearby gate with an array of triangular holes. A combined experimental and theoretical study shows that application of magnetic field leads to giant enhancement of the ratchet current and emergence of quantum magneto-oscillations, also featuring a complex Fano shape of the cyclotron resonance and well-pronounced electron spin resonance.

Guidelines for accurate and efficient calculations of mobilities in two-dimensional semiconductors

Jiaqi Zhou, Samuel Poncé, and Jean-Christophe Charlier

Phys. Rev. B 110, 125304 (2024) - Published 30 September, 2024

Reported carrier mobilities in two-dimensional materials predicted by ab initio calculations differ widely due to various approximations used in different studies, questioning the validity of the Boltzmann transport equation in monolayers. Here, the authors aim to settle the debate and study the impact of many computational choices and approximations, including pseudopotential, quadrupole correction, Berry connection, and spin-orbit coupling (SOC). Based on this, the authors propose a practical approach that balances high accuracy with computational efficiency.

Dzurak, and Andre Saraiva

Phys. Rev. B 110, 125414 (2024) - Published 10 September, 2024

The abundance of historical investment in the integrated circuit sector is playing a crucial role in the quantum era. Progress in semiconductor spin qubits recently enabled the incorporation of foundry-level fabrication techniques into quantum processors, paving the way for scalable and commercial quantum computing. However, current CMOS quantum processors, which use dense gate arrays to define quantum dots, are prone to electrostatic crosstalk due to capacitive coupling. This crosstalk, transferred through spin-orbit interactions, impacts the Larmor frequency of the spin qubits. Utilizing advanced simulation tools and measurements in several state-of-the-art CMOS quantum devices, the authors formulate here a framework illustrating how electric fields interact with electron spins in intricate arrays, offering vital insights for the development of this quantum technology.

Interlayer Raman modes in twisted bilayer transition metal dichalcogenides

Eileen Schneider, Kenji Watanabe, Takashi Taniguchi, and Janina Maultzsch

Phys. Rev. B 110, 125431 (2024) - Published 25 September, 2024

Interlayer coupling is crucial for the observation of twist-angle induced physical effects in twisted 2D layers. This paper presents a fast method to investigate the interlayer coupling in twisted bilayer transition metal dichalcogenides by Raman spectroscopy. Via resonant excitation near the C exciton energy of the material, so-called interlayer optical Raman modes become observable only if the layers are electronically coupled. The authors demonstrate this effect specifically for twisted bilayers of MoS2 and MoSe2 at multiple twist angles.

Engineering topology in graphene with chiral cavities

Ceren B. Dag and Vasil Rokaj

Phys. Rev. B 110, L121101 (2024) - Published 3 September, 2024

This work elucidates how the quantum nature of photons affects the topology of the correlated photoelectron hybrid wave function. The authors reveal a fundamental relation between the Berry phase and the properties of exchanged photons with matter at light-matter hybridization points in the Brillouin zone. Furthermore, the cavity-mediated electronic interactions in graphene valleys are analytically derived for the case where the material is subject to enhanced vacuum fluctuations in a chiral cavity.

Quantum oscillation signatures of the Bloch-Grüneisen temperature in the Dirac semimetal ZrTe5

S. Galeski et al.

Phys. Rev. B 110, L121103 (2024) - Published 10 September, 2024

The electron-phonon interaction is the most fundamental phenomenon governing the intrinsic resistance of metals at finite temperatures. In semimetals, there is a characteristic phonon energy scale: the Bloch-Grüneisen temperature (TBG). This separates the different regimes of e-p scattering and is the temperature at which the average phonon momentum becomes comparable to the Fermi momentum. Here, the authors show, through subkelvin experiments, that due effective recovery of Galilean invariance below TBG , the electronic liquid in small Fermi surface metals undergoes an anomalous increase of viscosity accompanied by an unconventional suppression of quantum oscillation amplitudes.

Weak-coupling theory of magic-angle twisted bilayer graphene

Jihang Zhu, Iacopo Torre, Marco Polini, and A. H. MacDonald

Phys. Rev. B 110, L121117 (2024) - Published 20 September, 2024

The discovery of exotic properties in magic-angle twisted bilayer graphene (MATBG) established two-dimensional moiré structures as an exciting new platform for strongly correlated physics. The distinct features of MATBG include a fourfold spin-valley flavor degeneracy and two extraordinarily flat topologically fragile low-energy bands. Here, the authors seek to gain new insights into MATBG physics by applying RPA theory, which accounts for dynamic screening of long-range Coulomb interactions and establishes the crucial influence of correlations in compressible metallic states in expanding unbroken symmetry regions in the MATBG phase diagram.

Inchworm quasi Monte Carlo for quantum impurities

Hugo U. R. Strand, Joseph Kleinhenz, and Igor Krivenko

Phys. Rev. B 110, L121120 (2024) - Published 24 September, 2024

Quantum impurity models are key for describing many-body effects in both open quantum systems and correlated quantum materials through embedding methods. Continuous time quantum Monte Carlo provides numerically exact solutions with 1/N convergence, where N is the number of samples. Here, the authors show how the imaginary time integration can be performed using quasi Monte Carlo yielding parametrically better 1/N convergence. Benchmarks of the open source implementation accompanying the paper are shown to enable calculations with unprecedented accuracy.

Berry-dipole semimetals

Zheng-Yang Zhuang, Chaoyi Zhang, Xiao-Jiao Wang, and Zhongbo Yan

Phys. Rev. B 110, L121122 (2024) - Published 26 September, 2024

The authors introduce here a class of topological semimetals, termed “Berry-dipole semimetals” (BDSMs), in three dimensions. Two representative characteristics in the Bloch band structure of BDSMs are the quadratic dispersion and dipole-structure Berry curvature near the band degeneracy. The BDSMs are shown to support a diversity of distinctive properties, such as anomalous paired Fermi arcs with identical spin polarization, anomalous Hall effect, orbital magnetic moment quantized in units of an effective Bohr magneton, and field orientation sensitive Landau levels.

Point defects in wide-band-gap semiconductors are leading qubit candidates for realizing quantum information processing. The authors investigate here the electronic structure and magneto-optical properties of scandium-related point defects in AlN, a material widely used in electronics and optoelectronics. The positively charged scandium−nitrogen-vacancy complex, which has a singlet ground state, exhibits a spin polarization cycle similar to the ST1 center in diamond, with long coherence time resulting from an electron spin being transferred to a nuclear spin, and large optically detected magnetic resonance readout contrast. These properties render the center promising for use as a quantum memory.

Here, focusing on the archetypal ferro-octupolar ordering in metallic heavy-fermion compounds, the authors demonstrate through a combination of semiclassical transport and general symmetry analysis that nonlinear Hall transport is the dominant experimental signature.

Phys. Rev. B 110, 125140 (2024) - Published 19 September, 2024

The authors introduce and analyze a novel example of a nonlocal model that violates the eigenstate thermalization hypothesis via Hilbert space fragmentation. This fragmentation manifests itself through the presence of a highly degenerate null space. The commutant algebra responsible for the fragmentation is a subalgebra of the Read-Saleur commutant of Temperley-Lieb models. The model studied resembles the Sachdev-Ye model, and its low-energy correlators are analyzed using similar techniques. Perturbations leading to quantum many-body scarring in the model are also considered.

Topological quantum phase transitions driven by a displacement field in twisted MoTe2 bilayers

Prakash Sharma, Yang Peng, and D. N. Sheng

Phys. Rev. B 110, 125142 (2024) - Published 20 September, 2024

The Chern bands in twisted MoTe2 semiconductor bilayers host fascinating quantum effects, including the fractional quantum anomalous Hall (FQAH) state at a zero magnetic field. This study explores the stability of 1/3 and 2/3 FQAH states under intermediate values of an externally applied out-of-plane electric displacement field, where the single-particle band topology remains unchanged. By demonstrating the nontrivial effects of electric fields on partially filled topological bands, the authors map a rich topological quantum phase diagram as a function of twist angles and displacement fields.

Unconventional topological mixed-state transition and critical phase induced by self-dual coherent errors

Phys. Rev. B 110, 125152 (2024) - Published 26 September, 2024

Topologically ordered phases host anyons that can condense, leading to a trivial gapped phase. Such a transition can be induced by coupling to an environment. This paper explores a scenario where the coupling between a topologically ordered phase and the environment maintains a self-duality symmetry that interchanges anyons with nontrivial mutual statistics. The authors find that this duality symmetry prevents anyon condensation and, further, for a range of the coupling strength, the topological phase is destroyed in favor of an exotic critical phase.

Here, the authors study the ratchet effect – the conversion of alternating fields in the terahertz and gigahertz range into direct current – using a 2D metamaterial formed by monolayer graphene and a nearby gate with an array of triangular holes. A combined experimental and theoretical study shows that application of magnetic field leads to giant enhancement of the ratchet current and emergence of quantum magneto-oscillations, also featuring a complex Fano shape of the cyclotron resonance and well-pronounced electron spin resonance.

Guidelines for accurate and efficient calculations of mobilities in two-dimensional semiconductors

Jiaqi Zhou, Samuel Poncé, and Jean-Christophe Charlier

Phys. Rev. B 110, 125304 (2024) - Published 30 September, 2024

Reported carrier mobilities in two-dimensional materials predicted by ab initio calculations differ widely due to various approximations used in different studies, questioning the validity of the Boltzmann transport equation in monolayers. Here, the authors aim to settle the debate and study the impact of many computational choices and approximations, including pseudopotential, quadrupole correction, Berry connection, and spin-orbit coupling (SOC). Based on this, the authors propose a practical approach that balances high accuracy with computational efficiency.

The abundance of historical investment in the integrated circuit sector is playing a crucial role in the quantum era. Progress in semiconductor spin qubits recently enabled the incorporation of foundry-level fabrication techniques into quantum processors, paving the way for scalable and commercial quantum computing. However, current CMOS quantum processors, which use dense gate arrays to define quantum dots, are prone to electrostatic crosstalk due to capacitive coupling. This crosstalk, transferred through spin-orbit interactions, impacts the Larmor frequency of the spin qubits. Utilizing advanced simulation tools and measurements in several state-of-the-art CMOS quantum devices, the authors formulate here a framework illustrating how electric fields interact with electron spins in intricate arrays, offering vital insights for the development of this quantum technology.

Interlayer coupling is crucial for the observation of twist-angle induced physical effects in twisted 2D layers. This paper presents a fast method to investigate the interlayer coupling in twisted bilayer transition metal dichalcogenides by Raman spectroscopy. Via resonant excitation near the C exciton energy of the material, so-called interlayer optical Raman modes become observable only if the layers are electronically coupled. The authors demonstrate this effect specifically for twisted bilayers of MoS2 and MoSe2 at multiple twist angles.
