This paper demonstrates that release-free phononic crystal cavities fabricated on lithium niobate can achieve strong electromechanical coupling with high-impedance microwave resonators and high quality factors at millikelvin temperatures, overcoming previous limitations of suspended devices while enabling scalable interfaces for quantum information systems.
This study demonstrates that voltage-induced hysteresis in Ge/SiGe heterostructures stems from charge trapping at the semiconductor-oxide interface, which increases electrostatic disorder and charge noise, thereby highlighting the critical need for conservative device tuning to optimize spin qubit performance.
By utilizing spin-orbit torque as a proxy for orbital current transport in Cr/X/Ni trilayers and comparing them to Pt/X/Ni systems, this study demonstrates that the interface transparency for orbital currents across 12 different spacers is comparable to or greater than that for spin currents.
This paper demonstrates that in a two-dimensional magnetophotonic crystal with nonreciprocal local resonances, extreme nonreciprocal transmission can occur without spectral nonreciprocity, revealing that the imaginary part of the complex wavevector, rather than the real part, solely determines the isolation ratio in subwavelength lattices.
This paper demonstrates both experimentally and theoretically that controlled nonlinear friction in a micromechanical oscillator can induce the coexistence of two distinct pairs of period-two states, a multistable phenomenon governed by a swallowtail catastrophe that expands the understanding of parametric resonance and nonequilibrium dynamics.
This paper derives exact coordinate and momentum distributions for a small composite system of a movable shell and internal particles, demonstrating that their distinct dependencies on particle number and degrees of freedom allow for the inference of internal structure while revealing a unique form of chaotic motion driven solely by internal impacts.
This study demonstrates that in noisy, realistic feedback-controlled systems, trajectory-based information thermodynamic bounds deteriorate rapidly, causing a crossover where Markovian mutual-information bounds become tighter and more robust than those relying on detailed trajectory statistics.
This paper demonstrates that native oxidation of chromium in NiFe/Cr bilayers creates a self-contained, highly efficient orbital-current source driven by Cr-O hybridization, enabling giant damping-like torque and field-free magnetization switching that significantly outperforms conventional heavy-metal benchmarks.
This paper introduces and analyzes "Mott-Thouless pumps" that achieve quantized charge transport in highly entropic, spin-incoherent Mott states by identifying conditions where a gapped charge sector remains dynamically decoupled from thermal spin fluctuations, while also characterizing scenarios where such protection fails.
This paper demonstrates that circularly polarized light can Floquet-engineer nearly flat electronic bands on the surface of three-dimensional topological insulators, enabling chiral superconductivity driven by repulsive Coulomb interactions with a predicted critical temperature of approximately 7 K.
