Quantum Electrodynamics of graphene Landau levels in a deep-subwavelength hyperbolic phonon polariton cavity

This contribution presents a theoretical framework for the quantum electrodynamics of graphene Landau levels within a deep-subwavelength hyperbolic phonon-polariton cavity, which elucidates the emergence of polaritons, distinguishes resonant quantum vacuum effects from electrostatic interactions, and analyzes the hybridization between magnetoplasmons and electromagnetic cavity modes.

Non-Hermitian catalysis of density-wave orders on Euclidean and hyperbolic lattices

This paper demonstrates that non-Hermitian hopping imbalances on bipartite Euclidean and hyperbolic lattices catalyze the formation of charge- and spin-density-wave orders at significantly weaker interaction strengths than in Hermitian systems by narrowing the band width while preserving the characteristic density of states scaling near zero energy.

An anisotropic functional for two-dimensional material systems

This paper addresses the limitations of isotropic exchange-correlation functionals in describing two-dimensional materials by introducing an anisotropic screened-exchange potential that accurately reproduces band gaps and the piecewise linearity of total energy.

High-Efficiency Tunable Microwave Photon Detector Based on a Semiconductor Double Quantum Dot Coupled to a Superconducting High-Impedance Cavity

This work demonstrates a highly efficient, tunable microwave photon detector that achieves nearly 70% efficiency by employing a semiconductor double quantum dot coupled to a high-impedance superconducting cavity and enables deterministic single-photon-to-charge conversion over a frequency range of 3–5.2 GHz.

Radial modes of pressure bumps and dips in astrophysical discs

This study employs wave topology to demonstrate that pressure extrema in astrophysical disks act as waveguides for specific topological modes, establishes analytical criteria for their existence, and highlights their potential as prime targets for future disk seismology.

Diffusive and hydrodynamic magnetotransport around a density perturbation in a two-dimensional electron gas

This paper theoretically demonstrates that in a two-dimensional electron gas under a strong magnetic field, a density perturbation with a power-law tail creates a large "no-go" region of exponentially suppressed current and a rotated Landauer resistivity dipole outside it, with these effects being further modulated by electron viscosity.

Dispersion of Anyon Bloch Bands

This paper analytically constructs single-anyon Bloch states in Fractional Chern insulators to reveal that their dispersion arises from many-body Berry phases, exhibits topological degeneracy, and is governed by quantum geometry non-uniformity and emergent magnetic translation symmetries that can suppress bandwidth through higher harmonic modulation.

Anomalous Mixed-State Floquet Topology in One-Dimensional Open Quantum Systems

This paper utilizes Floquet-Born-Markov theory to demonstrate that the $\mathbb{Z}\times\mathbb{Z}$ topological classification of periodically driven Su-Schrieffer-Heeger chains, characterized by ensemble geometric phases and protected edge modes in both $0$ and $\pi$ quasienergy gaps, robustly extends to dissipative, finite-temperature open quantum systems.
