This paper establishes that the Kardar-Parisi-Zhang (KPZ) scaling observed in the phase dynamics of polariton condensate arrays originates from fluctuations in Goldstone modes resulting from spontaneous symmetry breaking, thereby linking microscopic system parameters to the coherent properties of emitted light.
This study investigates nonreciprocal spin waves in CoFeB/NiFe bilayers by extending the dynamic matrix formalism to reveal that interlayer exchange interactions, alongside dipolar forces, drive frequency shifts in helical magnetization states, offering tunable sub-100 nm wavelengths for potential magnonic applications.
This paper demonstrates the simultaneous initialization, control, and readout of an 18-qubit modular array in germanium with high-fidelity single-qubit gates and entangling operations, establishing a scalable architecture for utility-scale semiconductor quantum processors.
The paper proposes "FerBo," a novel superconducting qubit that achieves robustness against both relaxation and dephasing by hybridizing fermionic Andreev levels with a bosonic LC circuit mode while leveraging phase-space wavefunction delocalization similar to fluxonium.
This paper proposes a theoretical protocol for reconstructing the full density matrix of a single-electron spin qubit by utilizing spin-polarized transport through ferromagnetic reservoirs to measure tunneling probabilities, which are then processed via machine learning to infer both population and phase information.
This paper identifies the staggered dampinglike spin-orbit torque as the key mechanism for the deterministic electrical switching of the Néel vector in antiferromagnets with inversion+time reversal symmetry, demonstrating this effect through first-principles calculations and spin dynamics analysis in n-doped bilayer CrI.
This paper presents an all-dielectric silicon-integrated metasurface composed of Si/GeSn core/shell nanowire arrays that enables polarization-tuned Fano resonances in the short-wave infrared spectrum, facilitating efficient refractive index sensing with a detection limit of 10⁻².
This paper employs Markovian Lindblad quantum dynamics to model electron transport in incoherently-driven molecular nanojunctions, demonstrating that the theory successfully reproduces key experimental features like negative differential conductance and Coulomb blockade while predicting light-induced currents in specific two-site configurations.
This paper employs a time-dependent Newns-Anderson-Schmickler model with Keldysh Green's functions and semiclassical trajectories to demonstrate how adsorbate motion and solvent coupling non-adiabatically suppress electron transfer while facilitating energy dissipation into electron-hole pairs, ultimately deriving an analytical expression for the average energy transfer rate in the slow-motion limit.
This paper introduces a radiofrequency electron-cascade readout method for silicon spin qubits that utilizes alternating-current electron co-tunnelling to achieve a signal-to-noise ratio enhancement of over 35 dB, enabling fast, high-fidelity singlet-triplet readout and coherent spin control without the need for proximal charge sensors.
