F. Le Mardelé, J. Wyzula, I. Mohelsky, S. Nasrallah, M. Loh, S. Ben David, O. Toledano, D. Tolj, M. Novak, G. Eguchi, S. Paschen, N. Barišić, J. Chen, A. Kimura, M. Orlita, Z. Rukelj, Ana Akrap, and D. Santos-Cottin

Phys. Rev. B 107, L241101 (2023) - Published 1 June, 2023

TlBiSSe is a 3D Dirac semimetal that exists at the interface between a topological insulator, TlBiS2, and a trivial insulator, TlBiSe2. It is one of the few systems with an ideal band structure, exhibiting only conical dispersive bands over almost half an electronvolt. Here, the authors find a rare unequivocal signature of a 3D Dirac cone in its optical and magneto-optical properties, achieved by carefully controlled synthesis that places the Fermi level very close to the Dirac point.

Inhomogeneous disordering at a photoinduced charge density wave transition

Antonio Picano, Francesco Grandi, and Martin Eckstein

Phys. Rev. B 107, 245112 (2023) - Published 7 June, 2023

Symmetry-breaking phase transitions are ubiquitous in nature. The study of their dynamics in solids has often been performed using homogeneous order parameter theories. By microscopically modeling the photoinduced melting and recovery of a charge density wave, the authors instead show here that the transient dynamics can lead to disordered state, where the average order parameter is not representative of the atomic-scale configuration. This provides a possible minimal model description of the experimentally proposed inhomogeneous disordering pathway in photoinduced phase transitions.

Ultrafast carrier dynamics and symmetry reduction in bismuth by nonperturbative optical excitation in the terahertz range

Matthias Runge, Ahmed Ghalgaoui, Isabel Gonzalez-Vallejo, Fabian Thiemann, Michael Horn-von Hoegen, Klaus Reimann, Michael Woerner, and Thomas Elsaesser

Phys. Rev. B 107, 245140 (2023) - Published 28 June, 2023

The semimetal bismuth displays a multifaceted nonlinear terahertz response, which is studied by two-dimensional terahertz (2D-THz) spectroscopy. Nonperturbative excitation drives intra- and interband electron transitions close to the narrow band gaps at the L points of the Brillouin zone, giving rise to pump-probe signals and high-harmonic generation. Preferential excitation in two of the six L valleys generates an anisotropic carrier distribution across the Brillouin zone, causing a hexagonal azimuthal angular dependence of the pump-probe signal. The concomitant symmetry reduction allows excitation of coherent phonon wavepackets along back-folded phonon coordinates.

Interacting topological quantum chemistry of Mott atomic limits

Phys. Rev. B 107, 245145 (2023) - Published 29 June, 2023

Topological quantum chemistry (TQC) is a successful framework for identifying noninteracting topological materials, based on the symmetry analysis of the Bloch Hamiltonian and on reference states known as atomic limits. However, TQC grinds to a halt once interactions are included. Here, the authors put forward a framework analogous to TQC, but employing n-particle Green’s function techniques to indicate topology in interacting systems. Fundamentally, they define a class of interacting reference states that generalize the notion of atomic limits, which they call Mott atomic limits. The reference states are symmetry protected topological states.

Significant phonon drag effect in wide band gap GaN and AlN

Yujie Quan, Yubi Chen, and Bolin Liao

Phys. Rev. B 107, 245202 (2023) - Published 14 June, 2023

Understanding the electrical and thermal transport properties of group-III nitride semiconductors is crucial for their electronic and thermoelectric applications. This study investigates the impact of the phonon drag effect, which refers to the momentum exchange between nonequilibrium phonons and electrons, on electronic transport in GaN and AlN. Results show that, even at room temperature, phonon drag significantly enhances mobility and the Seebeck coefficient. The study delves into the specific mechanisms for this.

Phys. Rev. B 107, 245304 (2023) - Published 22 June, 2023

Intense scrutiny over the last decade of experiments on a variety of platforms aiming to identify topological superconductivity has raised the stakes in this search. Because nontopological Andreev bound states at or near zero energy can resemble topological states, signatures beyond spectroscopy of zero-energy modes are called for. A key signature of a topological phase transition - namely, the closing and reopening of the superconducting gap - is mostly unobserved in previous experiments. Here, this phenomenon is reported in planar Josephson junction devices made from superconductor-semiconductor hybrid materials. Consistency between experiment and numerics, along with a number of other characteristic signatures, including dependence on phase, magnetic field, and chemical potential, support the conclusion that the observed gap closing and reopening, with associated appearance of a zero-bias conductance peaks upon reopening, are associated with topological transition.

Phys. Rev. B 107, 245407 (2023) - Published 6 June, 2023

The conduction band spin-orbit splitting ∆c has a strong impact on optical, transport, and spin-valley properties of 2D materials based on transition metal dichalcogenide monolayers. Here, the authors study charge tunable devices based on WSe2 and WS2 monolayers. In addition to the well-known radiative recombination of neutral and charged excitons, photoluminescence measurements highlight a weaker intensity optical transition. This line is interpreted as an impurity-assisted recombination of the negatively charged exciton (triplet trion), whose radiative recombination energy differs by ∆c from that of the trion’s direct optically active recombination.

Independent and coherent transitions between antiferromagnetic states of few-molecule systems

Molecular spintronics is usually based on paramagnetic or ferromagnetic (S ≠ 0) species. Here, the authors study small ensembles of two molecular antiferromagnets, {Mn4} and {Co4}, bound to carbon nanotube quantum dots. The current through the quantum dots shows a random telegraph signal caused by transitions between nondegenerate Stot = 0 states of individual molecular antiferromagnets. Statistical analysis shows that transitions between those states are independent in the case of {Co4} ensembles, while {Mn4} ensembles display long-lived coherent superposition involving multiple complexes.

Topological Andreev rectification

Pok Man Tam, Christophe De Beule, and Charles L. Kane

Phys. Rev. B 107, 245422 (2023) - Published 20 June, 2023

Quantized transport is a powerful probe of topological phases, and metals are topologically classified by the Euler characteristic of the Fermi sea. Here, the authors demonstrate analytically and numerically that a 2D metal proximitized by a Josephson π junction exhibits rectification for current along the junction. They introduce the rectified nonlocal conductance and show it is quantized by the Fermi sea topology. InAs-based heterostructures, as well as monolayer and bilayer graphene, are identified as promising platforms for demonstrating this effect.

InAs-Al hybrid devices passing the topological gap protocol

Morteza Aghaee et al. (Microsoft Quantum)

Phys. Rev. B 107, 245423 (2023) - Published 21 June, 2023

Topological phases of matter can enable highly stable qubits with small footprints, fast gate times, and digital control. These hardware-protected qubits must be fabricated with a material combination in which a topological phase can reliably be induced. The challenge: disorder can destroy the topological phase and obscure its detection. This paper reports on devices with low enough disorder to pass the topological gap protocol, thereby demonstrating gapped topological superconductivity and paving the way for a new stable qubit.

Iron oxide (FexO) serves as a model constituent of Earth-like planetary interiors, reflecting the distinctive high-pressure chemistry of their cores and rocky mantles. Under pressure it undergoes crystal structural transitions and metallization, accompanied by a local-moment collapse of Fe ions. Here, the experiments and theoretical calculations characterize the complex interplay between electron states and structural phases, resulting in a rich phase diagram and revealing the existence of a metallic high-spin state of iron at the conditions near those of Earth’s core-mantle boundary.

Electrically driven photon statistics engineering in quantum-dot circuit quantum electrodynamics

Lei-Lei Nian, Bo Zheng, and Jing-Tao Lü

Phys. Rev. B 107, L241405 (2023) - Published 14 June, 2023

Quantum-dot circuit quantum electrodynamics (QD-cQED) has enabled the probe and control of light-matter interaction at the elementary level, with the demonstration of nonclassical photon sources driven by inelastic electron tunneling. Due to the absence of the photon blockade mechanism, an general scheme for photon statistics engineering in QD-cQED is lacking. Based on current-driven joint interference effect, the authors propose here an all-electrical scheme to achieve arbitrary photon statistics with classical or quantum correlation by simply controlling bias voltage.

The semimetal bismuth displays a multifaceted nonlinear terahertz response, which is studied by two-dimensional terahertz (2D-THz) spectroscopy. Nonperturbative excitation drives intra- and interband electron transitions close to the narrow band gaps at the L points of the Brillouin zone, giving rise to pump-probe signals and high-harmonic generation. Preferential excitation in two of the six L valleys generates an anisotropic carrier distribution across the Brillouin zone, causing a hexagonal azimuthal angular dependence of the pump-probe signal. The concomitant symmetry reduction allows excitation of coherent phonon wavepackets along back-folded phonon coordinates.

However, TQC grinds to a halt once interactions are included. Here, the authors put forward a framework analogous to TQC, but employing n-particle Green’s function techniques to indicate topology in interacting systems. Fundamentally, they define a class of interacting reference states that generalize the notion of atomic limits, which they call Mott atomic limits. The reference states are symmetry protected topological states.

Understanding the electrical and thermal transport properties of group-III nitride semiconductors is crucial for their electronic and thermoelectric applications. This study investigates the impact of the phonon drag effect, which refers to the momentum exchange between nonequilibrium phonons and electrons, on electronic transport in GaN and AlN. Results show that, even at room temperature, phonon drag significantly enhances mobility and the Seebeck coefficient. The study delves into the specific mechanisms for this.

Intense scrutiny over the last decade of experiments on a variety of platforms aiming to identify topological superconductivity has raised the stakes in this search. Because nontopological Andreev bound states at or near zero energy can resemble topological states, signatures beyond spectroscopy of zero-energy modes are called for. A key signature of a topological phase transition - namely, the closing and reopening of the superconducting gap - is mostly unobserved in previous experiments. Here, this phenomenon is reported in planar Josephson junction devices made from superconductor-semiconductor hybrid materials. Consistency between experiment and numerics, along with a number of other characteristic signatures, including dependence on phase, magnetic field, and chemical potential, support the conclusion that the observed gap closing and reopening, with associated appearance of a zero-bias conductance peaks upon reopening, are associated with topological transition.

The conduction band spin-orbit splitting ∆c has a strong impact on optical, transport, and spin-valley properties of 2D materials based on transition metal dichalcogenide monolayers. Here, the authors study charge tunable devices based on WSe2 and WS2 monolayers. In addition to the well-known radiative recombination of neutral and charged excitons, photoluminescence measurements highlight a weaker intensity optical transition. This line is interpreted as an impurity-assisted recombination of the negatively charged exciton (triplet trion), whose radiative recombination energy differs by ∆c from that of the trion’s direct optically active recombination.

Molecular spintronics is usually based on paramagnetic or ferromagnetic (S ≠ 0) species. Here, the authors study small ensembles of two molecular antiferromagnets, {Mn4} and {Co4}, bound to carbon nanotube quantum dots. The current through the quantum dots shows a random telegraph signal caused by transitions between nondegenerate Stot = 0 states of individual molecular antiferromagnets. Statistical analysis shows that transitions between those states are independent in the case of {Co4} ensembles, while {Mn4} ensembles display long-lived coherent superposition involving multiple complexes.

Quantized transport is a powerful probe of topological phases, and metals are topologically classified by the Euler characteristic of the Fermi sea. Here, the authors demonstrate analytically and numerically that a 2D metal proximitized by a Josephson π junction exhibits rectification for current along the junction. They introduce the rectified nonlocal conductance and show it is quantized by the Fermi sea topology. InAs-based heterostructures, as well as monolayer and bilayer graphene, are identified as promising platforms for demonstrating this effect.

InAs-Al hybrid devices passing the topological gap protocol

Topological phases of matter can enable highly stable qubits with small footprints, fast gate times, and digital control. These hardware-protected qubits must be fabricated with a material combination in which a topological phase can reliably be induced. The challenge: disorder can destroy the topological phase and obscure its detection. This paper reports on devices with low enough disorder to pass the topological gap protocol, thereby demonstrating gapped topological superconductivity and paving the way for a new stable qubit.
