This study demonstrates that coupling a topological insulator-based Josephson junction to a dissipative environment induces spectral bifurcation and finite lifetimes for Majorana bound states, ultimately driving an anomalous supercurrent with a non-vanishing value at zero phase difference.
This paper demonstrates that continuous observation of electrons tunneling through a triple quantum dot system fundamentally reshapes tunneling dynamics by increasing the average occupation of the classically forbidden central dot, thereby resolving the paradox of detecting particles in virtual states through the interplay of weak localization and strong measurement-induced jumps.
Using quantum Monte Carlo simulations, this paper demonstrates that a bilayer of antiparallel dipolar excitons with a 1:2 density ratio supports a trimer superfluid phase at low temperatures and densities, which undergoes a quantum phase transition to a two-superfluid state and exhibits distinct thermal disordering pathways, with potential realization in transition metal dichalcogenide heterostructures.
By combining lattice simulations with an extended field theory analysis that incorporates one-loop renormalization of weak topological terms, this study reveals that while weak topology induces an intermediate quasi-localized phase in chiral symmetry classes, the theoretically predicted stable strong-coupling fixed point and spatially anisotropic scaling suggest that the numerically observed quasi-localized phase may be an artifact of assuming isotropic scaling in finite-size analyses.
This study demonstrates room-temperature spin injection and preservation in exciton-polaritons within a monolithic Tamm-plasmon microcavity embedding 2D halide perovskites, where rapid polariton decay outcompetes spin relaxation mechanisms to enable potential applications in chiral lasers and switches.
This study demonstrates that identifying single-photon emitters in hexagonal boron nitride using atomic-resolution ADF-STEM is fundamentally limited by sample thickness (beyond ~17 layers) and susceptible to misidentification due to residual threefold astigmatism, rendering the technique unreliable for the thicker flakes typically used in photonic research.
This paper proposes a non-abelian geometric quantum energy pump that utilizes transitionless driving and a counterdiabatic term to coherently transport states within a degenerate subspace, where the net energy transfer is determined by the non-abelian Berry-curvature tensor and the Euler class, offering potential applications as a quantum transducer, charger, or metrological tool across various physical platforms.
This paper demonstrates a tunable double-junction transmon qubit featuring a Josephson potential with magnetic-flux-controlled harmonics, where spectroscopy reveals a second harmonic amplitude up to ~10% and identifies a flux sweet spot that eliminates dispersive shifts by balancing couplings to internal and qubit modes.
This paper introduces a new generation of quantum-enabled spintronic antennas that overcome the efficiency limitations of traditional miniaturized devices, enabling embedded applications, single-element beam steering, and stealth capabilities for secure communication.
This paper demonstrates that nonlinear magnon interactions, specifically pump-induced nondegenerate three-magnon splitting, dynamically generate double anticrossings by creating two distinct magnon populations that independently couple to the Kittel mode.
