Universal aspects of bulk density of states in non-Hermitian lattices

This paper demonstrates that despite apparent boundary sensitivity, non-Hermitian lattice systems possess a universal bulk density of states characterized by identical multipole moments and finite-time dynamics across different boundary conditions, with the Brown measure serving as a canonical representative and point-gap topology providing a systematic criterion for when boundary-dependent eigenvalue accumulation retains physical significance.

Direct signatures of Anderson orthogonality catastrophe in nonequilibrium quantum dots

This paper proposes experimental schemes to directly observe the Anderson orthogonality catastrophe in nonequilibrium quantum dots by utilizing rate equation formalism to demonstrate how specific observables robustly depend on the AOC exponent α\alpha under voltage or thermal bias, thereby supporting recent experimental findings.

Nonrelativistic-Ising superconductivity in p-wave magnets

This paper proposes that p-wave magnets, a newly discovered class of materials with noncollinear real-space magnetization and non-relativistic spin splitting, uniquely support Ising superconductivity characterized by a 50:50 singlet-triplet Cooper pair mixture and enhanced resilience against pair breaking, distinguishing them from both conventional antiferromagnets and altermagnets.

Establishing the Magnetoelastic Origin of Spin-Wave Routing through Focused Ion Beam Patterning

This study establishes a physically validated framework explaining the non-monotonic spin-wave steering in FIB-irradiated YIG by linking dispersion changes to a three-phase evolution of magnetoelastic strain, thereby enabling the precise design of programmable magnonic devices.

The "Moiré Capacitor Effect" and Stabilization of Fractional Chern Insulators in Rhombohedral Graphene Superlattices

This paper introduces the "Moiré Capacitor Effect" as a mechanism that electrostatically enhances the moiré potential in rhombohedral graphene-hBN superlattices, thereby stabilizing a parent Chern insulator state and enabling the emergence of Fractional Chern Insulators through inter-band fluctuations, which explains the state's experimental observation in aligned samples and its absence in unaligned ones.

Exceptional activated mode theory for generalized real-complex transitions

This paper introduces a general, non-perturbative activated-mode principle that determines real-to-complex spectral transition thresholds across diverse non-Hermitian systems by identifying a small, variationally determined Hilbert subspace where spectral detuning and projected couplings compete, thereby recasting these transitions as generic mode-selection problems independent of specific symmetries.

Thermal Hall tomography of chiral superconductivity in rhombohedral graphene

This paper proposes that rhombohedral graphene offers a unique platform to directly measure the Bogoliubov–de Gennes Chern number of chiral superconductivity via thermal Hall conductance, bypassing the limitations of magnetic imaging and complex normal-state reconstruction by leveraging the material's specific electronic structure and existing millikelvin thermometry capabilities.

Edge physics and the Casimir interaction in Maxwell--Chern--Simons theory on a strip

This paper investigates Maxwell-Chern-Simons theory on a strip using the Symanzik framework to derive admissible boundary conditions, establish two boundary U(1)U(1) current algebras, and calculate the Casimir interaction energy, revealing a transition from long-range power-law forces in the Maxwell limit to Yukawa-suppressed interactions due to topological mass in the full theory.
