This paper proposes a general construction principle for non-Hermitian topological operators in any dimension that maintain real eigenvalues and robust zero-energy boundary modes without exhibiting the non-Hermitian skin effect, thereby extending the bulk-boundary correspondence to a broad class of non-Hermitian insulators and semimetals.
Motivated by recent experiments, this paper derives general expressions for photonic heat transport through a Josephson junction in a dissipative environment, demonstrating that the heat current remains sensitive to Josephson coupling on the insulating side with opposite behaviors for series and parallel configurations, while also predicting heat rectification properties.
The authors developed a compact, low-power (1 µW) tunnel diode oscillator operating at 140 MHz with enhanced amplitude stability and phase noise (-115 dBc/Hz at 1 MHz offset), demonstrating its suitability for scalable qubit readout in semiconductor and liquid helium systems.
This study demonstrates the amplification of microwave pulses using a single-qubit engine fueled by quantum measurement backaction, validating indirect work estimation methods and confirming the system's stability against decoherence and drifts.
This paper predicts that confining light in infrared cavities can control the Ginzburg-Landau stiffness of superconductors by renormalizing the Cooper-pair kinetic mass through photon-mediated repulsive interactions, an effect that is particularly significant in low-temperature materials and tunable via cavity length.
This study reveals a rich phase diagram in semimetallic rhombohedral hexalayer graphene, characterized by electric-field-driven band inversion, dual-carrier superconducting-like states, and a novel ferroelectric orbital magnetism that exhibits sharp, reversible magnetic switching under unipolar electric fields.
This paper proposes that nematic order in multilayer graphene enhances superconductivity by breaking symmetry to reshape Bloch wavefunctions and amplify the quantum metric, thereby significantly boosting pairing strength through the quantum geometric Kohn-Luttinger mechanism.
This paper demonstrates that noninteracting -state Fock parafermions on a one-dimensional lattice can be mapped to simpler -state parafermions (or fermions when is a power of two), enabling the construction of solvable parafermionic Hamiltonians with single-particle spectra identical to their fermionic counterparts.
This paper presents a quantum mechanical framework for acoustoelectric amplification in a piezoelectric-2DEG heterostructure, demonstrating that a 2DEG enables efficient phonon amplification across a broad range of wavelengths and deriving the gain, noise, and saturation characteristics necessary for designing quantum phononic lasers and amplifiers.
This paper demonstrates that Rashba spin-orbit coupling in armchair honeycomb nanoribbon heterostructures drives a topological phase transition characterized by gap closing and reopening, thereby generating robust, symmetry-protected interface states without altering the underlying lattice structure.
