This paper demonstrates a compact RF gate-dispersive charge readout method for Ge/SiGe quantum dots, showing that integrating a single-hole box significantly enhances the signal-to-noise ratio and readout speed compared to direct detection, despite limitations imposed by dielectric loss.
This paper proposes a theoretical model demonstrating that defect pairs with strong local electron-phonon coupling generate coherent phonon interference patterns whose intensities and topological structures can be controlled by internal parameters and directly measured via the Huang-Rhys factor, offering a novel platform for exploring nonequilibrium quantum phenomena.
This perspective paper argues that the chirality-induced spin selectivity (CISS) effect can be understood through fundamental symmetry considerations, demonstrating that it does not violate parity or time-reversal symmetries and thereby providing a robust conceptual framework for interpreting experimental results and guiding future research.
This study investigates the impact of mass disorder on nearest-neighbor tight-binding models across three distinct hyperbolic lattices, revealing that while the Dirac liquid phase remains stable against weak disorder before undergoing sequential semimetal-to-metal and metal-to-insulator transitions, the other two systems exhibit only the latter transition, with critical exponents closely resembling those found in on-site potential disorder scenarios.
This paper presents a theoretical and numerical study of hydrodynamic electron flow in gated graphene, demonstrating that a non-linear boundary-layer model successfully explains the experimentally observed non-Poiseuille velocity profiles with maxima near the edges, offering insights into non-topological edge currents.
This study demonstrates that photoemission orbital tomography can experimentally identify all molecular orbitals of bisanthene on a Cu(110) surface across a 10 eV binding energy range, providing a rigorous benchmark that reveals the range-separated hybrid functional HSE performs best and suggests Kohn-Sham orbitals approximate Dyson orbitals more accurately than previously thought.
This paper proposes Zeeman quantum geometry as a novel diagnostic tool to detect unconventional magnets with momentum-dependent spin-splitting and zero net magnetization by identifying their unique intrinsic gyrotropic magnetic currents, which persist even when conventional quantum geometry responses vanish.
This paper resolves the Marcus-Rehm-Weller paradox by demonstrating that the contrasting predictions of rate decrease versus saturation in electron transfer arise from the same two-state quantum Hamiltonian, with the specific behavior determined by whether the system operates in the nonadiabatic or adiabatic limit.
This paper proposes that the displacement-field-driven hysteretic switching of superconductivity in ferroelectric bilayer T-MoTe arises from the suppression of intralayer - orbital pairing by ferroelectric polarization, establishing a specific condition for switching and predicting anisotropic pairing gaps and potential pair density wave transitions.
This paper proposes that the displacement component of the linear intrinsic gyrotropic magnetic response in magnetic topological insulator-unconventional magnet interfaces serves as a high-fidelity, experimentally measurable fingerprint for identifying and distinguishing the symmetry of unconventional magnetic orders through its unique angular harmonics and sign-reversal patterns.
