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.
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 bilayers.
This paper introduces DSpinGNN, a physics-informed equivariant graph neural network that accurately predicts dynamic magnetic exchange couplings in strain-deformed monolayer CrI, enabling large-scale simulations that reveal mesoscopic exchange textures and domain wall behaviors inaccessible to traditional first-principles methods.
This paper establishes a universal framework for Berry-phase-based topological charges in two-dimensional quasicrystals, demonstrating a unique higher charge of in systems and revealing a corresponding -fold winding of electromagnetic field patterns in photonic quasicrystals as a direct experimental signature.
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 point, thereby enabling electric-field control of the Chern number and realizing a tunable Chern insulator with phases ranging from to .
This paper demonstrates that tuning the intrinsic momentum-dependent exchange field of a 3D -wave magnet against gate-induced Rashba spin-orbit coupling establishes a generalized symmetry, which protects a Persistent Spin Helix to enable robust, disorder-resilient spin-logic devices with high-visibility electrical conductance oscillations.
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.
This paper demonstrates that reversible uniaxial strain can precisely and elastically control the doping and bandgap of suspended single-wall carbon nanotube quantum dots through quantum transport straintronics, offering a capacitive-free mechanism for applications in qubits and molecular transistors.
This paper theoretically demonstrates that in monolayer WSe, spin- and valley-resolved quantum transport can be precisely controlled through the combined modulation of barrier velocity and scalar potential, revealing strong anisotropy, resonant tunneling, and tunable polarized currents via an effective massive Dirac Hamiltonian framework.
This paper introduces a systematic optimal control procedure to enhance the performance of non-adiabatic Thouless pumps by simultaneously optimizing average transport rates and minimizing noise, thereby enabling independent control over charge and spin currents and their fluctuations in quantum dot systems.
