This paper demonstrates the generation of energy-time entangled photons from a single InGaAs/GaAs quantum dot monolithically grown on a silicon substrate, achieving coherent control via two-photon excitation and observing phase-dependent two-photon interference with visibilities approaching the threshold for Bell inequality violation.
This paper proposes a zero-field Hall drag effect as a direct transport signature of chiral superconductivity, where a finite quasiparticle current in an open-circuit chiral superconductor mediates a transverse voltage in an adjacent normal layer, abruptly appearing below the critical temperature with a sign determined by the order parameter's phase winding.
Using a quantum twisting microscope, researchers directly imaged the interacting energy bands of magic angle twisted bilayer graphene, revealing that its dual electronic nature arises from light and heavy components at different momenta within the same flat bands, thereby resolving long-standing puzzles about its quantum phases.
This study demonstrates high-performance, normally-off n- and p-type nanoribbon transistors with 25–30 nm channel dimensions fabricated from monolayer transition metal dichalcogenides using a multi-patterning process, achieving record-breaking on-state currents that validate top-down patterning as a viable strategy for future nanosheet transistors.
This study demonstrates time-resolved charge detection in molybdenum disulfide (MoS) quantum dots, enabling the observation of individual tunneling events and few-electron regimes to establish a promising platform for spin- and valley-to-charge conversion in quantum information applications.
Using determinant quantum Monte Carlo simulations, this study demonstrates that increasing electron-phonon coupling in the half-filled Haldane-Holstein model triggers a first-order transition from a Chern insulator to a staggered charge-density wave, leading to a discontinuous collapse of topological order characterized by the vanishing of many-body topological invariants and the loss of boundary spectral weight.
This paper argues that the reported phonon Tesla valve cannot achieve true two-terminal thermal rectification within the fixed-background linearized phonon Boltzmann transport equation framework, as such a model inherently yields equal thermal resistance in both forward and reverse directions for passive systems.
This paper demonstrates that a -symmetric quantum impurity model with complex-conjugate boundary Kondo interactions exhibits a monotonic decrease in impurity entropy from to $0$ as it flows from the ultraviolet to the infrared Kondo-screened regime, thereby extending the understanding of entropy flow beyond the standard assumptions of the -theorem in non-Hermitian many-body systems.
This paper proposes that the interplay between real-space crystalline defects and momentum-space optical vortices in disordered topological materials significantly enhances bulk photovoltaic currents through skew scattering, creating a unique sensitivity to material topology, defect symmetry, and light polarization that can be exploited via a targeted experimental program.
This paper introduces the position space Chern number () as a topological index for chiral magnetic systems that guarantees edge-localized in-gap states, generalizes the skyrmion winding number, and reveals a fundamental obstruction to simultaneously possessing both non-zero position and momentum space topological indices.
