This paper demonstrates that while strong light-matter coupling can modify Hall conductivity, the quantized Hall resistivity remains completely robust against cavity-induced polariton broadening at zero temperature, thereby explaining the experimental absence of renormalization in the von Klitzing constant.
This paper establishes a multiband bulk-boundary correspondence for nonlinear systems by introducing an auxiliary-system formalism that enables the classification of hybrid-order topological phases, demonstrating how uniform and dimerized stacking of 2D nonlinear eigenvalue systems can engineer distinct 3D first-, second-, and third-order topological states.
This paper demonstrates a spin-orbit torque-driven synthetic antiferromagnetic oscillator in a nanoconstriction that exhibits both linear eigenmodes and complex nonlinear self-oscillatory dynamics near the spin-flop transition, establishing a promising platform for advanced spintronic signal processing and reservoir computing.
This study proposes the Janus MgAlB_2 MBene as a superior anode material that leverages intrinsic out-of-plane polarization to achieve ultrafast lithium diffusion, a high theoretical capacity of 1470.24 mAh/g, and minimal volume expansion, thereby demonstrating a novel design strategy for high-performance two-dimensional electrode materials.
This paper utilizes a reduced two-mode autoparametric resonance model to demonstrate that the nonlinear sensitivity of phononic frequency combs to physical perturbations is highly non-uniform and parameter-dependent, revealing distinct response mechanisms for detuning, drive amplitude, and damping that provide a coherent framework for engineering optimized nonlinear sensing platforms.
This paper investigates phase transitions in a non-Hermitian extended Su-Schrieffer-Heeger model by demonstrating that Krylov spread complexity and entanglement entropy effectively signal topological changes and dynamical phases under different evolution protocols, while momentum-resolved complexity further elucidates the underlying characteristic modes driving these transitions.
This paper demonstrates that a gate-tunable suspended graphene nanomechanical resonator can be dynamically switched between distinct nonlinear regimes—functioning as a frequency multiplier, a broadband phononic comb source, or a chaotic generator—by exploiting 1:2 internal resonance to control quadratic and cubic coupling coefficients.
This theoretical study demonstrates that the combined application of mechanical strain and external scalar potential provides independent, dual-knob control over spin and valley polarization in monolayer MoS, enabling highly tunable quantum transport and electrostatic spin inversion for advanced spintronic and valleytronic applications.
This paper investigates the interplay between local defects and topology in the Haldane model, demonstrating that vacancies with an odd sublattice imbalance host protected zero-energy modes characterized by a invariant and distinguished from trivial defects by unique wavefunction dislocations, fractional charge accumulation, and reversed probability currents.
This paper presents a unified, auditable analytical framework that links CMOS lithographic geometry to electrostatic confinement and many-electron spin observables in asymmetric multigate quantum devices, thereby enabling design-technology co-optimization for CMOS-based qubits.
