This paper demonstrates the first application of THz near-field photovoltage nanoscopy to image nanoscopic weak spots in superconductors with 300 nm resolution, revealing how defects enhance vortex-antivortex pair nucleation and influence light-matter interactions.
This paper investigates electron scattering from chiral spin textures like skyrmions across all coupling strengths, revealing new features such as Ramsauer-Townsend minima and resonances that significantly influence topological and spin Hall conductivities, particularly in the strong-coupling regime relevant to real materials.
This study develops a ReaxFF reactive force field for GaN to demonstrate that externally applied electric fields non-linearly and anisotropically modulate defect migration barriers through charge-lattice coupling, offering critical insights for device reliability in high-field environments.
This paper theoretically demonstrates that a localized magnetic field effectively confines massive Dirac fermions in monolayer WSe quantum dots by suppressing Klein tunneling and generating tunable quasibound states, offering a promising mechanism for controlling spin-valley transport in transition metal dichalcogenide nanostructures.
This paper demonstrates that chemically treating tungsten disulfide (WS) with a super-acid to passivate sulfur vacancies effectively eliminates hysteresis and enables the use of WS as a scalable, high-performance encapsulant for graphene, achieving room-temperature mobilities comparable to state-of-the-art hexagonal boron nitride devices.
This paper presents a novel non-classical micro-antenna that utilizes spin-momentum locking in a three-dimensional topological insulator to generate highly efficient, anisotropic electromagnetic radiation from a sub-wavelength source, enabling beam steering without a phased array.
This study reports the discovery of a diverse family of unconventional superconductivities in clean rhombohedral tetralayer and pentalayer graphene, characterized by magnetic-field-induced enhancements and robustness far exceeding the Pauli limit, while demonstrating that proximitized spin-orbit coupling further expands this phase diagram to enable the engineering of non-Abelian quasiparticles.
This paper presents a Hamiltonian-independent framework based on the one-particle density matrix that extends the mode-shell correspondence to characterize higher-order topological phases, including fractional shell indices and robustness against structural disorder in amorphous systems.
This paper proposes that canted antiferromagnetic order in two-dimensional -electron kagome systems can generate a quantum anomalous Hall effect with potentially maximal Chern numbers () via intrinsic Berry curvature and scalar spin chirality, even in the absence of external magnetic fields or spin-orbit coupling.
This paper establishes that perfect equilibrium superconducting diodes are thermodynamically forbidden due to free energy continuity constraints, explaining why high rectification efficiencies in real devices typically rely on non-equilibrium conditions, metastability, or external drives rather than intrinsic equilibrium properties.
