This paper proposes and numerically validates a mechanism where impurities induce a thermal crossover from fractional to integer quantum anomalous Hall states in rhombohedral multilayer graphene, driven by the competition between thermal excitation energy penalties and entropy gains.
This paper demonstrates that the coexistence of upstream charge and neutral modes in the quantum Hall state leads to significantly enhanced electrical and thermal Hall conductances, providing a clear diagnostic signature for edge reconstruction.
This paper introduces a novel quantum platform utilizing unstrained germanium channels on lattice-matched strained SiGe barriers to eliminate metamorphic defects, demonstrating high-mobility hole gases and unique spin properties that make it a promising candidate for scalable, fast quantum hardware and hybrid systems.
This paper demonstrates that simple nanoscale thermoelectrics utilizing potential barriers or quantum point contacts (modeled as step transmissions) achieve near-ideal efficiency across all finite power outputs and in the presence of heat leaks, significantly outperforming double-barrier structures (modeled as Lorentzian transmissions) which only excel at vanishing power.
This paper presents a unified theoretical framework for thermalization and heat transport in a one-dimensional diatomic hard-point gas by mapping a phase diagram that reveals three universal dynamical regimes—kinetic, hydrodynamic, and intermediate—across the spectrum from near-integrable to far-from-integrable systems, thereby challenging conventional views on system-size dependence and establishing a consistent description of relaxation dynamics.
This paper derives a universal analytic formula for the tunneling magnetoresistance (TMR) in junctions of -wave magnets (including altermagnets), revealing that while their TMR ratio scales linearly with magnetization strength and is generally smaller than that of ferromagnets, their zero net magnetization makes them promising candidates for high-speed, ultra-dense memory applications.
This paper demonstrates a 2.2-fold acceleration in initializing SiGe quantum dots into the single-electron regime by combining a neural network-based autotuning algorithm with FPGA-accelerated RF-reflectometry measurements, which collectively reduced stability diagram acquisition time by a factor of 9.8.
This study demonstrates that dynamic dipolar coupling between a CoFeB artificial spin ice and an underlying NiFe film induces robust magnon-magnon interactions, resulting in a distinct triplet spectral feature and enabling the selective enhancement of specific spin-wave wavelengths for magnonic signal transport.
This paper analyzes a non-topological Majorana qubit protected by quantum frustration arising from distinct spatial profiles, demonstrating that while the mechanism effectively mitigates Ohmic and some sub-Ohmic noise, it fails against prevalent noise due to spontaneous symmetry breaking and catastrophic decoherence.
This paper demonstrates that field-free deterministic switching of perpendicular ferromagnets can be achieved in noncentrosymmetric Weyl semimetals, such as PrAlGe, by leveraging higher-order harmonics of spin-orbit torque to create new stable magnetization states, even in the presence of in-plane mirror symmetries.
