This paper demonstrates that the common assumption of local heat generation in semiconductor devices breaks down on micrometer scales due to ballistic phonon transport, causing non-local heating that can exceed local heating and contradict Fourier's law even at temperatures far above cryogenic levels.
This paper establishes a discrete-to-continuum limit via -convergence for atomistic systems with rigid interactions, demonstrating that the resulting continuum energy concentrates on grain boundaries and decomposes into twice the solid-vacuum transition energy due to the energetic unfavorability of solid-solid interpolating layers.
This study employs a transfer-matrix approach to demonstrate how uniaxial zigzag strain, energy gaps, and laser-modulated electrostatic barriers collectively govern electron transmission in gapped graphene, revealing strain-induced Fano oscillations and tunable transport properties that could advance optoelectronic device applications.
This Perspective article outlines the potential of magnetic domain walls as a scalable platform for universal quantum computing, highlighting their dual role as stationary and flying qubits, identifying promising material platforms, and discussing the key requirements, challenges, and future experiments needed to advance this emerging field at the intersection of magnetism and quantum information science.
This paper theoretically investigates how interactions between a near-resonant two-level system and thermally activated two-level fluctuators degrade the coherence of a coupled oscillator, revealing distinct regimes of coherence oscillations and non-exponential decay that depend on coupling strengths and fluctuator transition rates.
This paper presents a magnonic true random number generator that leverages stochastic switching in the bistable regime of spin-wave dynamics on a yttrium iron garnet microstrip to produce high-quality random bitstreams at 20 Mb/s, demonstrating both NIST compliance and scalability to nanoscale dimensions.
This study demonstrates that inter-subband coupling in multichannel Rashba nanowire Josephson junctions qualitatively alters the topological phase diagram and significantly enhances the Josephson diode effect, enabling nonreciprocal supercurrents even under Zeeman fields aligned with the spin-orbit direction—a mechanism absent in single-channel systems.
This paper demonstrates the successful in-situ monitoring of short-lived radical species in liquid-phase chemical reactions by utilizing nitrogen-vacancy (NV) centers in nanodiamonds to detect concentration-dependent changes in spin relaxation time, achieving sensitive detection of TEMPO radicals in the nanomolar range.
This paper proposes a cavity-based scheme that utilizes photonic chirality to control the braiding and readout of non-Abelian anyons in fractional quantum Hall systems by creating a rotating pinning landscape that maps braid operations onto measurable cavity intermode coherence, offering a robust alternative to fragile electronic interference methods.
The study reports the observation of spatially-resolved, opposite-sign longitudinal voltage reversals along the edges of BiSrCaCuO Hall bar devices above the critical current, attributing this phenomenon to particle-hole symmetry breaking in moving vortices and the formation of opposing Bernoulli potentials driven by invasive voltage contacts.
