This paper proposes and numerically analyzes a transmon-based multilevel quantum battery that achieves remarkable energy storage and extraction control through sequential interactions with coherent ancillary two-level systems, demonstrating performance within the reach of current quantum circuit technology.
This paper proposes using nitrogen-vacancy center spin-qubit noise magnetometry to detect distinctive magnetic noise signatures that characterize the dynamical transition between algebraic spin correlations and vortex proliferation in two-dimensional XY magnets, thereby enabling the quantitative study of Berezinskii-Kosterlitz-Thouless physics.
This paper presents a combined time-dependent density functional theory and quantum electrodynamics model to accurately predict the optical response and population dynamics of hydrogen-saturated graphene quantum dots, demonstrating strong agreement with experimental results.
This paper pioneers the direct experimental measurement of the non-Abelian quantum geometric tensor in a six-band photonic lattice using a novel orbital-resolved polarimetry technique, thereby enabling the characterization of non-Abelian quaternion charges, Euler curvature, and quantum metrics to unlock the study of complex multi-gap topological phases.
This paper utilizes quantum kinetic and quasiclassical theories to demonstrate that the interplay between superconductivity and altermagnetism in disordered systems generates competing magnetoelectric effects and proximity-induced magnetization, leading to novel phenomena such as spin-texture induction and $0$- transitions in Josephson junctions.
This study presents experimental evidence of a unique spin-valley locked state in the bulk Dirac material BaMnBi2, characterized by a four-fold degeneracy and supported by observations of stacked quantum Hall and nonlinear Hall effects, thereby establishing a new platform for valleytronic applications distinct from its sister compound BaMnSb2.
This study establishes the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction as a sensitive magnetic probe capable of distinguishing between axion insulator and quantum anomalous Hall phases in MnBiTe films by analyzing distinct signatures arising from intrinsic magnetism, band properties, and light-induced phase transitions.
First-principles-based atomistic simulations reveal that ultrathin freestanding ferroelectric oxide layers host a diverse range of controllable topological polar textures, including liquid-like domains, helix-waves, and chiral bubbles, establishing them as promising platforms for future ferroic devices.
This paper presents a unified theoretical framework demonstrating that while quantum confinement alone can induce superconductivity in bulk non-superconducting metals only within extremely narrow, sub-nanometer thickness windows, combining confinement with proximity effects in heterostructures can substantially enhance critical temperatures even in materials that are non-superconducting in bulk form.
Using density functional theory with spin-orbit coupling, this study reveals strong nonparabolicity in the dispersion curves of charge carriers in orthorhombic CsPbI at specific energy thresholds and proposes a quadratic model to accurately describe these dependences across the Brillouin zone.
