Temporal glide symmetry enforces a parity sideband selection rule in scalar bulk media

This paper demonstrates that temporal glide symmetry in scalar time-modulated media enforces a strict parity selection rule for frequency conversion, allowing modes to emit only into specific transverse-parity sidebands depending on whether the sideband index is odd or even.

Non-Hermitian Skin Effect Along Hyperbolic Geodesics

This paper introduces a geodesic-based framework and a corresponding geodesic-periodic boundary condition to investigate the non-Hermitian skin effect in non-reciprocal hyperbolic lattices, revealing that spectral sensitivity is governed by geodesic boundaries and non-reciprocal directionality while requiring boundary localization to distinguish skin modes due to the extensive boundary volume inherent to hyperbolic geometry.

Topological Charge-2ne Superconductors

This paper establishes a unified theoretical framework for topological charge-$2ne$ superconductors by deriving them from charge- $2e$ ingredients and quantum Hall states, constructing their corresponding bulk and edge field theories, and demonstrating that they host fermionic non-abelian topological orders with direct implications for experimental detection.

Universal critical behavior in ideal Bose-Einstein condensation

This paper establishes a unified framework demonstrating that the critical behavior of ideal Bose-Einstein condensation falls into three distinct classes determined solely by the low-energy scaling of the density of states, which is governed by dimensionality and confinement.

Extrinsic quantum geometry in the quadrupolar bulk photovoltaic effect

This paper identifies a previously neglected electric quadrupole contribution to the photon drag effect in centrosymmetric crystals, framing it as an extrinsic multiband metric tensor that predicts anomalously large bulk photovoltaic responses in systems with strong multi-band admixing, such as twisted MoTe $_2$ bilayers.

DSpinGNN: A Physics-Informed Equivariant Graph Neural Network for Dynamic Magnetic Exchange Prediction in Strain-Deformed Monolayer CrI $_3$

This paper introduces DSpinGNN, a physics-informed equivariant graph neural network that accurately predicts dynamic magnetic exchange couplings in strain-deformed monolayer CrI $_3$ , enabling large-scale simulations that reveal mesoscopic exchange textures and domain wall behaviors inaccessible to traditional first-principles methods.

Berry-phase-based Topological Charge in Quasicrystals and their Observable Features in Photonic System

This paper establishes a universal framework for Berry-phase-based topological charges in two-dimensional quasicrystals, demonstrating a unique higher charge of $C=4$ in $C_{8v}$ systems and revealing a corresponding $C$ -fold winding of electromagnetic field patterns in photonic quasicrystals as a direct experimental signature.

Ferroelectric Altermagnetic Chern Insulator in magnetic field: electrical control of the Chern number

This paper proposes a theoretical model demonstrating that combining an external magnetic field, spin canting, and ferroelectric orbital hybridization in a d-wave altermagnet lifts degeneracy at the $\Gamma$ point, thereby enabling electric-field control of the Chern number and realizing a tunable Chern insulator with phases ranging from $C = \pm 1$ to $C = \pm 2$ .

Robust Spin Logic Enabled by Generalized $\mathrm{SU}(2)$ Symmetry in $p$ -Wave Magnets

This paper demonstrates that tuning the intrinsic momentum-dependent exchange field of a 3D $p$ -wave magnet against gate-induced Rashba spin-orbit coupling establishes a generalized $\mathrm{SU}(2)$ symmetry, which protects a Persistent Spin Helix to enable robust, disorder-resilient spin-logic devices with high-visibility electrical conductance oscillations.

Interfacial Coupling and Sparse Intercalation of 7-Atom-Wide Armchair Graphene Nanoribbons by N-Heterocyclic Carbene Monolayers

This study demonstrates that the intercalation efficiency of N-heterocyclic carbene monolayers beneath 7-atom-wide armchair graphene nanoribbons on Au(111) is critically governed by the molecular adsorption geometry, where flat-lying methyl-substituted dimers enable partial decoupling while bulky isopropyl-substituted monomers prevent intercalation.
