This paper demonstrates that reversible uniaxial strain can precisely and elastically control the doping and bandgap of suspended single-wall carbon nanotube quantum dots through quantum transport straintronics, offering a capacitive-free mechanism for applications in qubits and molecular transistors.
This paper theoretically demonstrates that in monolayer WSe, spin- and valley-resolved quantum transport can be precisely controlled through the combined modulation of barrier velocity and scalar potential, revealing strong anisotropy, resonant tunneling, and tunable polarized currents via an effective massive Dirac Hamiltonian framework.
This paper introduces a systematic optimal control procedure to enhance the performance of non-adiabatic Thouless pumps by simultaneously optimizing average transport rates and minimizing noise, thereby enabling independent control over charge and spin currents and their fluctuations in quantum dot systems.
This paper introduces a scalable framework combining diagrammatic formalism and numerical methods to model many-body interactions in surface-code quantum processors, revealing how residual crosstalk can invert interaction hierarchies and drive the system into distinct operational regimes to guide the optimization of next-generation hardware.
This paper proposes and theoretically validates the nonlinear magnetoelectric Edelstein effect, a novel mechanism that generates intrinsic spin magnetization in -invariant non-centrosymmetric insulators via interplaying magnetic and electric fields, while also offering an extrinsic route for detecting Néel vector reversal in antiferromagnetic materials.
This study demonstrates that in GdFeCo ferrimagnets, spin currents generated by the spin Hall effect (from Gd 5d electrons) and the spin anomalous Hall effect (from FeCo 3d electrons) maintain distinct signs and symmetries across the magnetization compensation temperature, revealing that these mechanisms originate from separate electronic subsystems and do not invert their torque signs despite changes in net magnetization.
This study demonstrates coherent micrometer-range spin-wave transport in a hybrid artificial spin ice system by leveraging exchange-mediated coupling and evanescent tunneling to overcome the limitations of weak dipolar interactions, thereby enabling the investigation of spin-wave phenomena in frustrated magnetic lattices for potential analog signal processing applications.
Using a large- renormalization group approach, this paper demonstrates that three-dimensional generalized Weyl semimetals with monopole charge exhibit an anisotropic marginal non-Fermi liquid phase driven by amplified Coulomb interactions, characterized by intrinsically anisotropic screening and power-law quasiparticle suppression, in contrast to the isotropic behavior found in systems with .
This study demonstrates that hydrothermally grown chiral tellurium nanowires exhibit phase-coherent quasi-ballistic transport, gate-tunable quantum dot formation, and highly anisotropic g-factors, establishing them as a versatile platform for spin qubits and Majorana zero mode research.
This paper demonstrates that the transconductance of multilayer WSe field-effect transistors can serve as a direct electrical spectrometer for measuring intervalley relaxation times, offering three distinct signatures—Lorentzian frequency response, two-stage current transients, and sweep-rate-proportional hysteresis—that provide quantitative access to this parameter using standard instrumentation.
