This paper demonstrates that mobile electron architectures utilizing large spin shuttling oscillations can achieve high-fidelity single-qubit gates with superior Rabi frequencies and reduced charge noise compared to static methods, provided that spin-valley physics bottlenecks are mitigated through quantum optimal control.
This paper proposes a strategy for designing two-dimensional conducting organic ferrimagnets by combining Aza-3-Triangulene and 2-Triangulene molecules in a honeycomb lattice, which exhibits half-metallicity, strong magnetic exchange couplings, and a topological gap leading to quantized Hall conductance at ultra-low temperatures.
This paper investigates superconductors coupled with various -wave magnets (), revealing that altermagnets stabilize chiral topological superconductors with Majorana chiral edge states characterized by Chern numbers, while odd-parity magnets induce topological superconductors with Majorana flat bands characterized by winding numbers.
This study demonstrates quantum-projection-noise-resolved readout of a strongly-interacting 2D ensemble of nitrogen-vacancy centers in diamond, enabling the direct observation of how intrinsic dipolar interactions transform isotropic quantum noise into an anisotropic profile and paving the way for entanglement-enhanced solid-state sensing.
This paper proposes that entropy from Goldstone or soft gapped modes drives finite-temperature transitions between competing extended integer and fractional quantum Hall regimes, offering a bulk mechanism to explain the thermal evolution observed in moiré rhombohedral graphene.
This study utilizes large-scale reactive molecular dynamics to demonstrate that coercive fields in ZnO-based wurtzite ferroelectrics are governed by unscreened local polar order at the advancing inversion-boundary filament head, revealing that charge redistribution and heterostructuring can effectively suppress this barrier to reduce the coercive field by approximately 50%.
This paper demonstrates that the quantum Mpemba effect in a linearly coupled quantum harmonic oscillator arises from initial-slip dynamics caused by the sudden switch-on of system-bath interactions, which generate transient correlations essential for enabling a system initially farther from equilibrium to relax faster than one closer to it, even beyond weak-coupling and Markovian approximations.
This paper demonstrates that the universal 1/3 suppression of diffusive shot noise, previously observed only at cryogenic temperatures, can be realized at room temperature using ferrocene redox cycling in a microfluidic gap, thereby bridging mesoscopic physics and electrochemistry.
This study demonstrates that nonadiabatic quantum pumping in an antiferromagnetic chain driven by time-dependent potentials can generate and control pure spin currents with negligible net charge transfer by exploiting frequency-dependent spin-channel separation and chemical potential tuning.
This study utilizes the self-consistent Bogoliubov-de Gennes formalism to demonstrate that in a one-dimensional hybrid ring, quasiperiodicity (via the AAH model) suppresses the magnitude of proximity-induced superconductivity and enhances spatial fluctuations, while hopping dimerization (via the SSH model) governs the oscillatory behavior and penetration depth of the induced pairing, with their combined interplay offering a versatile mechanism for controlling superconducting correlations in quasiperiodic systems.
