This paper proposes a microscopic model for surface roughness scattering in MOSFET inversion layers that accounts for the stochastic nature of roughness position, revealing that the scattering rate is intrinsically nonlocal and that conventional Fermi's golden rule approaches tend to underestimate SR-limited mobility under strong fields and low electron energies.
This paper demonstrates that helium focused ion beam irradiation can create tunable nanoscale potential barriers at oxide interfaces, allowing a single device to transition between thermionic emission, direct tunneling, and Fowler-Nordheim tunneling regimes via electrostatic gating.
This paper derives fundamental quantum limits on the total achievable steady-state squeezing in bosonic networks based on canonical commutation relations and stability, demonstrating how different driving schemes and mode counts affect these bounds.
This paper theoretically investigates how magnetic dipolar interactions mediate coupling between magnetostatic and Lamb waves in ferromagnetic thin films, predicting the emergence of hybridization gaps in their dispersion relations.
The paper reports that electron spin resonance in a planar Si-MOS quantum dot exhibits an enhanced Rabi frequency near a valley level anti-crossing due to electric-dipole transitions activated by inter-valley spin coupling, offering a potential mechanism for fast all-electrical spin control.
This paper proposes a theoretical framework for realizing robust, tunable Majorana bound states at the corners of a two-dimensional semi-Dirac system by inducing effective p-wave pairing in its anisotropic edge states through the interplay of Rashba spin-orbit coupling, a Zeeman field, and s-wave superconductivity.
This paper investigates how combining spin-orbit and spin-transfer torques in top-pinned SOT-MRAM devices causes reliability issues like backhopping and switching asymmetry, and proposes using STT pulse shaping as a strategy to mitigate these errors and improve switching robustness.
This paper analyzes how residual Casimir and magnetic-dipole interactions between particles and their shields, exacerbated by mechanical fluctuations and thermal vibrations, can create decoherence or false signals that threaten the detection of gravitationally induced entanglement.
This paper presents exact mathematical identities that allow the density-density correlation functions of all states within a spin multiplet to be derived from the highest-weight state, a method the authors use to analytically and numerically calculate the energies of various fractional quantum Hall states.
The paper proposes that applying tensile or unstrained engineering to germanium heterostructures can overcome the suppression of spin splitting caused by compressive strain, thereby enabling the realization of Andreev spin qubits with GHz-range spin splittings and fast all-electric quantum gates.
