This study demonstrates that spin-to-charge conversion in sputtered MoTe/Py heterostructures is predominantly governed by the interfacial Rashba-Edelstein effect rather than bulk transport, as evidenced by thickness-independent spin-torque efficiencies observed via spin-pumping and spin-torque ferromagnetic resonance measurements.
This paper demonstrates that intrinsic magnetic-field gradients from residual nuclear spins in Si/SiGe double quantum dots can be utilized to perform exchange oscillations and characterize device parameters at zero applied magnetic field, offering a simple, high-throughput diagnostic tool for hybrid semiconductor-superconductor qubits without the need for micromagnets or complex calibration.
This paper demonstrates that a dc-voltage-biased SQUID can engineer multi-photon dissipation (converting one, two, or four photons into a single lossy photon) while suppressing parasitic nonlinearities, offering a viable route for stabilizing cat qubits and reservoir engineering.
Using exact diagonalization of Dirac fermions on a sphere to leverage full symmetry and circumvent the parity anomaly, this study demonstrates that the interaction-driven multicritical point of the two-dimensional Chern insulator transition belongs to the Gross-Neveu-Yukawa universality class, with extracted operator scaling dimensions showing strong agreement with conformal bootstrap predictions.
This paper establishes that spin-orientation correlations arising from spin-orbit coupling in chiral molecules constitute the microscopic origin of chirality-induced spin selectivity, effectively defining an "enantio-sensitive molecular compass" that links photoelectron spin polarization to molecular orientation.
This paper demonstrates that incorporating projective measurements to enable transitions between qubit encodings overcomes the limitations of pure braiding in topological quantum computing, thereby restoring computational universality and achieving high-fidelity, fault-tolerant operations on systems with up to ten qubits.
This paper establishes a unified theoretical framework for topological charge-$2ne$ superconductors by deriving them from charge- ingredients and quantum Hall states, characterizing their bulk and edge properties through field theories that predict fermionic non-abelian topological orders.
This paper presents an efficient, expandable kinetic Monte Carlo platform that models electron transport through chiral molecules by independently treating spin channels, thereby quantifying spin filtering and reproducing the voltage-dependent asymmetry characteristic of electric Magnetochiral Anisotropy (eMChA) to help elucidate the microscopic origins of chiral-induced spin phenomena.
This paper presents and experimentally validates a unified compact model that accurately simulates the electrical characteristics of diverse emerging transistor technologies—including OSFETs, 2DFETs, CNFETs, and cryogenic MOSFETs—by integrating quantum confinement, trap charges, band-tail states, and temperature-dependent transport mechanisms across various operating regimes.
This paper demonstrates that collinear altermagnetism provides a viable route to realize elusive three-dimensional chiral higher-order topological insulators protected by symmetry by gapping surface Dirac cones to generate chiral hinge channels, and identifies promising material classes for their experimental realization.
