This paper demonstrates that moiré-engineered graphene Josephson junctions can sustain phase-coherent superconductivity up to 6 Tesla by utilizing dispersive magnetic Bloch bands within the Hofstadter spectrum to overcome the magnetic field limitations that typically suppress conventional Josephson transport.
This paper proposes a buckled elemental silicon kagome lattice that exhibits strain-controlled tuning of electronic flat bands and a transition from crystalline order to amorphous disorder, suggesting its potential as a stable platform for studying correlated electron physics.
This study reveals that multi-tunneling interference in noncentrosymmetric insulators under strong DC electric fields generates a significantly amplified, oscillating nonreciprocal response driven by the shift vector, thereby advancing the systematic understanding of quantum geometric effects in the nonperturbative regime.
This paper extends a previously developed Redfield-equation-based approach to address the flaws of the relaxation time approximation in predicting nonlinear responses, offering a corrected framework for studying nonlinear and nonequilibrium phenomena in noncentrosymmetric insulators.
This paper investigates X-ray photoemission in simple metals within the time domain to reveal coherent interference effects and methodological advances, specifically comparing complementary time-dependent eNRG algorithms against analytical and numerical benchmarks to address strong core-hole potentials.
This paper introduces a second-quantized field theory for Chern insulators featuring a static, lattice-periodic vector potential that breaks time-reversal symmetry, enabling the derivation of globally defined expressions for topological invariants in two and three dimensions and generalizing the quantum anomalous Hall effect to the optical regime.
This study introduces an ancillary ligand engineering strategy using phosphoryl-functionalized ligands to synthesize uniform, ultrathin CsPbI3 nanoplatelets with controlled self-assembly, enabling the fabrication of highly efficient light-emitting diodes with a record 13.1% external quantum efficiency and enhanced polarization properties.
This paper investigates how high-order Van Hove singularities in the valence band of two-dimensional semiconductors dramatically enhance the density of states and reshape the energy dispersions of excitons and trions, offering a pathway to engineer specific bound states for novel optical applications in materials like monolayer -SnAs.
This paper theoretically proposes and analyzes a method for dispersively detecting single propagating microwave photons in a circuit quantum electrodynamics setup using a double quantum dot, demonstrating how a photon can induce measurable changes in electronic occupation while highlighting associated measurement-induced backaction effects.
This paper demonstrates that magnetic quantum oscillations in three-dimensional nodal-ring semimetals can directly detect the hidden monopole charge through a distinct topological phase shift in the oscillation harmonics when the magnetic field is aligned with the ring axis, a signature predicted to be observable in weakly doped ABC-stacked graphdiyne.
