This paper analytically and numerically demonstrates that a quantum-dot-based Aharonov-Bohm interferometer with superconducting terminals is spectrally equivalent to a simpler side-coupled system, revealing how geometric factors and side-mode competition govern Andreev bound state spectra and induce a Josephson diode effect.
This study provides both theoretical and experimental evidence that polariton-like behavior can emerge in a two-dimensional exciton-cavity system by crossing an exceptional point, demonstrating that such effects occur even when the conventional strong coupling condition is not met.
This paper predicts that exciting magnons in a disordered antiferromagnetic Josephson junction significantly enhances the stationary supercurrent across long junctions, offering a promising mechanism for superconducting spintronics applications.
This paper demonstrates high-fidelity (99.8%) bucket-brigade spin shuttling in a silicon MOS device and reveals that residual errors are highly sensitive to the ratio between interdot tunnel coupling and Zeeman splitting, a relationship validated by a four-level Hamiltonian model to guide future quantum architecture optimization.
This paper investigates how a strong impurity coupled to the topological boundary of an infinite SSH heterojunction induces bonding and antibonding states within the bulk gap, resulting in a characteristic interference effect in the local density of states that manifests as a transition from a single peak to a double-peak structure.
This paper presents a dual-mode mechanical sensing method that utilizes Duffing coefficients and amplitude measurements to eliminate amplitude-to-frequency noise conversion, thereby achieving high stability in micromechanical sensors even when operating beyond the linear regime.
This paper theoretically demonstrates and simulates that an AC magnetic field induces unidirectional gliding motion in a cycloidal spin structure within a ferromagnetic thin film, generating a substantial DC voltage via spin motive forces that could be utilized for energy harvesting.
By combining Corbino-geometry transport experiments in ultraclean GaAs/AlGaAs quantum wells with Hartree--Fock elasticity and Kosterlitz--Thouless--Halperin--Nelson--Young melting theory, this study quantitatively predicts the melting temperatures of quantum Hall bubble crystals, thereby validating the defect-mediated melting framework for strongly interacting electronic solids.
This paper demonstrates the deterministic optical charging and electrical tuning of a quantum dot molecule to create spin-photon interfaces, revealing remarkably long spin-relaxation times and confirming the system's potential for generating multidimensional photonic cluster states.
This paper introduces RESOLUTE, a novel Ramsey correlation spectroscopy protocol utilizing phase cycling and population imbalance storage that extends effective coherence time beyond the standard limit, enabling the detection of low-frequency signals such as C nuclear spin precession in regimes previously inaccessible to single quantum sensors.
