Impedance spectroscopy of chiral symmetric topoelectrical circuits

Selma Franca, Torsten Seidemann, Fabian Hassler, Jeroen van den Brink, and Ion Cosma Fulga

Phys. Rev. B 109, L241103 (2024) - Published 5 June, 2024

While topoelectrical circuits are a successful tool for realizing various topological phases of matter, experiments mostly focus on detecting topological boundary phenomena originating from an underlying circuit Laplacian. Here, the authors introduce appropriate signal processing techniques that allow the recovery of the full spectrum of the chiral symmetric system from a single two-point impedance measurement. The robustness of these techniques is demonstrated by constructing the Fibonacci topoelectrical circuit for the first time, suggesting that topoelectrical circuits are an ideal metamaterial platform for studying different properties of quasi(crystalline) systems.

Gapless symmetry-protected topological phases and generalized deconfined critical points from gauging a finite subgroup

Lei Su and Meng Zeng

Phys. Rev. B 109, 245108 (2024) - Published 5 June, 2024

This work taps into the idea of gauging finite subgroups of global symmetries in conventional systems to obtain unconventional phases and phase transitions, greatly expanding the conventional Landau paradigm. Assisted by analytical anomaly computations and numerical density-matrix renormalization group calculations, the authors map the ordinary superfluid-insulator transition of the Bose-Hubbard model to novel phase transitions between exotic topological and/or symmetry-breaking phases. The general framework has potential applications in cold atom experiments and digital quantum simulators.

Maxim Trushin, Liangtao Peng, Gargee Sharma, Giovanni Vignale, and Shaffique Adam

Phys. Rev. B 109, 245118 (2024) - Published 13 June, 2024

A Fermi liquid of electrons is known to be unstable towards a superconducting state even with weak electron pairing. Here, the authors demonstrate theoretically that the Fermi liquid is also unstable to a frozen-like state that is enabled by electron pairing across the band touching point in a flat-band system. Like the surface of water covered by ice, this frozen Fermi liquid is hard to disturb making the electron flow immune to impurity scattering.

Hyperdeterminants and composite fermion states in fractional Chern insulators

Xiaodong Hu, Di Xiao, and Ying Ran

Phys. Rev. B 109, 245125 (2024) - Published 20 June, 2024

Writing down wavefunctions for fractional quantum Hall states was a milestone of condensed matter physics. Here, the authors achieve this goal for the newly discovered fractional quantum anomalous Hall effect (FQAHE), by developing a projective construction for composite fermion (CF) states, and revealing hyperdeterminants as a general structure for electronic wavefunctions. This construction is able to capture the microscopics, and is used to compute many observables in FCI states that are hard to do via traditional methods, including CF dispersion and the magnetoroton spectrum.

Applicability of Eliashberg theory for systems with electron-phonon and electron-electron interaction: A comparative analysis

Shang-Shun Zhang, Zachary M. Raines, and Andrey V. Chubukov

Phys. Rev. B 109, 245132 (2024) - Published 24 June, 2024

The applicability of Eliashberg theory, for fermions interacting with fluctuations of a soft collective boson near a quantum-critical point (QCP) in two dimensions, remains a subject of debate. The velocity of the soft boson is comparable to the Fermi velocity. Hence, Migdal’s justification of Eliashberg theory is formally not applicable. The authors argue here that some elements of Migdal’s reasoning remain valid because the collective boson is overdamped, yet vertex corrections to Eliashberg theory are O(1). At the same time, they show that these corrections are numerically small, at least near an Ising-nematic QCP.

Longitudinal (curvature) couplings of an N-level qudit to a superconducting resonator at the adiabatic limit and beyond

Rusko Ruskov and Charles Tahan

Phys. Rev. B 109, 245303 (2024) - Published 14 June, 2024

Understanding the coupling of superconducting (SC) wires to solid state qubits is vital to the design of quantum computers. To date, there has not been a complete theory applicable to all parameter regimes, from the traditional dispersive regime of circuit QED to the resonance regime to the far-off resonance situation in the adiabatic regime. This work presents that theory in the context of modulated longitudinal coupling, which promises to enhance the readout and coupling speed and fidelity through a resonator of solid-state qubit operations.

Single-photon emitters in WSe2: Critical role of phonons on excitation schemes and indistinguishability

Luca Vannucci, José Ferreira Neto, Claudia Piccinini, Athanasios Paralikis, Niels Gregersen, and Battulga Munkhbat

Phys. Rev. B 109, 245304 (2024) - Published 17 June, 2024

Quantum emitters in few-layer WSe2 hold promise for scalable quantum computation. However, a significant challenge is to prepare the emitter in a specific excited state “on-demand”. Here, the authors demonstrate that the emitter-phonon coupling has a crucial influence on the state preparation fidelity, because such a coupling is orders of magnitude stronger in WSe2 compared to other platforms. While excitation with resonant laser pulses is found to be significantly damped by phonons, alternative strategies based on detuned pulses allow for fast and reliable state preparation.

Effects of spin-orbit coupling in a valley chiral kagome network

P. Wittig, F. Dominguez, and P. Recher

Phys. Rev. B 109, 245429 (2024) - Published 26 June, 2024

Chern mosaic systems exhibit weakly protected chiral modes propagating in the bulk of the material. This novel phase of matter has recently been found in twisted bilayer graphene and double-aligned graphene-hexagonal boron nitride. Here, the authors investigate the spectrum and transport properties of a valley chiral kagome scattering network. The interplay of the network geometry, magnetic field, and spin-orbit coupling gives rise to peculiar interference phenomena, including a sizable zero-field spin polarization of the conductance.

Electronic transport, metal-insulator transition, and Wigner crystallization in transition metal dichalcogenide monolayers

Yi Huang and Sankar Das Sarma

Phys. Rev. B 109, 245431 (2024) - Published 26 June, 2024

By analyzing transport data from high-mobility transition metal dichalcogenide (TMD) WSe2 monolayers and considering realistic disorder scattering, the authors explain here the observed nonmonotonic carrier density dependence of mobility and the linear temperature-dependent resistivity in the metallic phase. They theoretically examine the metal-insulator transition (MIT) critical density and the melting temperature of Wigner crystallization (WC), suggesting that the observed two-dimensional low-density MIT likely results from the complex interplay between disorder effects and interaction-driven WC physics.

Anomalous Fermi pockets on the Hund's metal surface of Sr2RuO4 induced by correlation-enhanced spin-orbit coupling

Takeshi Kondo, Masayuki Ochi, Shuntaro Akebi, Yuyang Dong, Haruka Taniguchi, Yoshiteru Maeno, and Shik Shin

Phys. Rev. B 109, L241107 (2024) - Published 6 June, 2024

Much attention has been given to the spin-orbit coupling (SOC) effect on strongly correlated systems. Here, the authors investigate the electronic structure of the surface layer consisting of rotated RuO6 octahedrons in strongly correlated Sr2RuO4. They demonstrate that the octahedral rotation generates small Fermi pockets. Furthermore, it enhances the strong correlation, which increases the effective SOC, causing high orbital mixing. This result reasonably explains why the orbital-selective Mott transition is not realized in perovskite oxides with crystal distortion of octahedral rotation and tilt.

Electronic excitation spectra of molecular hydrogen in phase I from quantum Monte Carlo and many-body perturbation methods

Vitaly Gorelov, Markus Holzmann, David M. Ceperley, and Carlo Pierleoni

Phys. Rev. B 109, L241111 (2024) - Published 11 June, 2024

The electronic excitations in solid molecular hydrogen at room temperature for pressures varying from 5 to 90 GPa are calculated using quantum Monte Carlo methods and many-body perturbation theory. A crossover from a wide-gap insulator to a semiconductor is observed, showing the changing nature of the excitations from localized molecular (left inset figure) to delocalized (right inset figure) excitations. These findings are in agreement with experimental results, demonstrating the capability of accurately predicting band gaps in many-body systems with strong zero point and thermal effects.

Preston

Phys. Rev. B 109, L241112 (2024) - Published 12 June, 2024

The authors implement here a setup for ultrahigh resolution measurements of x-ray Thomson scattering spectra, with a spectral range of several tens of eV. As an example, they study the Al plasmon and resolve longstanding discrepancies between ab initio simulations and experiments. By fully utilizing the capabilities of modern XFEL facilities, the setup opens up new avenues for the diagnosis of matter under extreme conditions, as they occur in inertial fusion energy applications and astrophysical objects.

Integer and fractional quantum anomalous Hall effects in pentalayer graphene

Ming Xie and Sankar Das Sarma

Phys. Rev. B 109, L241115 (2024) - Published 21 June, 2024

Through a critical analysis of transport data from the recently discovered fractional quantum anomalous Hall effect (FQAHE) in rhombohedral pentalayer graphene on hBN, the authors identify here significant discrepancies between the FQAHE and the conventional fractional quantum Hall effect in Landau levels. Most notably, the excitation gap remains nearly constant for all observed fractions, starkly contrasting with the “v”-shaped linear dependence on |ν-1/2| predicted by the composite fermion model. This uncovers an intriguing puzzle regarding the nature of the FQAHE states.

Stochastic methodology shows molecular interactions protect two-dimensional polaritons

Nadine C. Bradbury, Raphael F. Ribeiro, Justin R. Caram, and Daniel Neuhauser

Phys. Rev. B 109, L241303 (2024) - Published 12 June, 2024

Using stochastic trace techniques, the authors simulate molecular aggregate crystals of millions of dyes inside Fabry-Pérot cavities containing many modes of light. They show that strong intermolecular interactions in the aggregate protect the formation of a polariton state in the face of strong molecular disorder due to persistent delocalization of the molecular dark states.

Emergence of radial Rashba spin-orbit fields in twisted van der Waals heterostructures

Tobias Frank, Paulo E. Faria Junior, Klaus Zollner, and Jaroslav Fabian

Phys. Rev. B 109, L241403 (2024) - Published 12 June, 2024

The Rashba effect is quintessential in condensed matter physics, appearing in virtually any electronic heterostructure. Its well-known manifestation is a tangential spin texture. Here, the authors theoretically demonstrate the emergence and engineering of radial Rashba spin textures in twisted van der Waals heterostructures using rigorous first-principles simulations and phenomenological modeling. These predictions offer new opportunities for controlling spin manipulation, as well as tuning correlated states and superconductivity in the van der Waals realm.

Quartet tomography in multiterminal Josephson junctions

David Christian Ohnmacht, Marco Coraiola, Juan José García-Esteban, Deividas Sabonis, Fabrizio Nichele, Wolfgang Belzig, and Juan Carlos Cuevas

Phys. Rev. B 109, L241407 (2024) - Published 26 June, 2024

The authors propose here how to detect quartets in hybrid multiterminal Josephson junctions from the analysis of the current-phase relation and Andreev bound state (ABS) spectra. The methods are applied to the partial ABS spectrum of a three-terminal Josephson junction realized in an InAs/Al heterostructure, which is extracted from spectroscopic measurements with the help of a deep-learning algorithm. The authors’ analysis confirms the existence of quartets in these hybrid structures and illustrates their close relationship with ABS hybridization.

Phys. Rev. B 109, 245125 (2024) - Published 20 June, 2024

Writing down wavefunctions for fractional quantum Hall states was a milestone of condensed matter physics. Here, the authors achieve this goal for the newly discovered fractional quantum anomalous Hall effect (FQAHE), by developing a projective construction for composite fermion (CF) states, and revealing hyperdeterminants as a general structure for electronic wavefunctions. This construction is able to capture the microscopics, and is used to compute many observables in FCI states that are hard to do via traditional methods, including CF dispersion and the magnetoroton spectrum.

The applicability of Eliashberg theory, for fermions interacting with fluctuations of a soft collective boson near a quantum-critical point (QCP) in two dimensions, remains a subject of debate. The velocity of the soft boson is comparable to the Fermi velocity. Hence, Migdal’s justification of Eliashberg theory is formally not applicable. The authors argue here that some elements of Migdal’s reasoning remain valid because the collective boson is overdamped, yet vertex corrections to Eliashberg theory are O(1). At the same time, they show that these corrections are numerically small, at least near an Ising-nematic QCP.

Understanding the coupling of superconducting (SC) wires to solid state qubits is vital to the design of quantum computers. To date, there has not been a complete theory applicable to all parameter regimes, from the traditional dispersive regime of circuit QED to the resonance regime to the far-off resonance situation in the adiabatic regime. This work presents that theory in the context of modulated longitudinal coupling, which promises to enhance the readout and coupling speed and fidelity through a resonator of solid-state qubit operations.

Single-photon emitters in WSe2: Critical role of phonons on excitation schemes and indistinguishability

Quantum emitters in few-layer WSe2 hold promise for scalable quantum computation. However, a significant challenge is to prepare the emitter in a specific excited state “on-demand”. Here, the authors demonstrate that the emitter-phonon coupling has a crucial influence on the state preparation fidelity, because such a coupling is orders of magnitude stronger in WSe2 compared to other platforms. While excitation with resonant laser pulses is found to be significantly damped by phonons, alternative strategies based on detuned pulses allow for fast and reliable state preparation.

Chern mosaic systems exhibit weakly protected chiral modes propagating in the bulk of the material. This novel phase of matter has recently been found in twisted bilayer graphene and double-aligned graphene-hexagonal boron nitride. Here, the authors investigate the spectrum and transport properties of a valley chiral kagome scattering network. The interplay of the network geometry, magnetic field, and spin-orbit coupling gives rise to peculiar interference phenomena, including a sizable zero-field spin polarization of the conductance.

Electronic transport, metal-insulator transition, and Wigner crystallization in transition metal dichalcogenide monolayers

Yi Huang and Sankar Das Sarma

Phys. Rev. B 109, 245431 (2024) - Published 26 June, 2024

By analyzing transport data from high-mobility transition metal dichalcogenide (TMD) WSe2 monolayers and considering realistic disorder scattering, the authors explain here the observed nonmonotonic carrier density dependence of mobility and the linear temperature-dependent resistivity in the metallic phase. They theoretically examine the metal-insulator transition (MIT) critical density and the melting temperature of Wigner crystallization (WC), suggesting that the observed two-dimensional low-density MIT likely results from the complex interplay between disorder effects and interaction-driven WC physics.
