Below are the most recent papers in this dynamic area of condensed matter physics, ready for you to explore.
This paper proposes a measurement protocol for the gauge-invariant Aharonov-Anandan geometric phases of Floquet states, demonstrating that their experimental requirements are comparable to those of previous adiabatic phase measurements.
This paper extends Polyakov's renormalization group method to systems with local anisotropies and non-local dipolar interactions by introducing "parallel transport of frames," demonstrating that integrating out short-wavelength fluctuations generates emergent local anisotropies essential for correctly describing the topology of the spin reorientation transition in ultrathin ferromagnetic slabs.
This paper presents microwave characterization of epitaxial Al-InAs Josephson junction arrays, demonstrating their tunability via out-of-plane magnetic fields to extract current-phase relations and effective transparency while highlighting their potential for high-inductance quantum circuits and the study of Andreev states.
This paper proposes a theoretical mechanism where a circularly polarized pump induces a giant Faraday and Kerr rotation in a lattice of conducting disks via a third-order nonlinear orbital response that generates a high-frequency Hall conductivity, significantly enhanced near plasmon resonance without relying on the inverse Faraday effect.
This paper presents a general non-Markovian framework for simulating nonequilibrium vibronic dynamics in molecule-metal systems that utilizes coordinate-dependent quantum colored noise via Markovian embedding, demonstrating superior accuracy and robustness over conventional Markovian approximations in modeling charge transport through vibrationally coupled molecular junctions.
This paper demonstrates that steady-state electrical current in single-molecule junctions serves as a robust, measurable fingerprint of strong light-matter coupling, offering a new transport-based method to probe and control polaritonic states beyond traditional optical spectroscopy.
This paper establishes global upper bounds and constructs explicit Hamiltonians for the maximal absolute Chern numbers of finite-range hopping extensions of the Qi–Wu–Zhang model, revealing that these limits are determined by both the maximum number of Dirac points and the specific mass-sign patterns assignable to them.
This paper investigates the interaction between Rydberg excitons in core-shell CuO nanostructures and surface plasmons, focusing on the enhancement of quadrupole transitions and the influence of nanostructure geometry on electric field amplification.
This paper presents a comprehensive theory for calculating the -factor in Si/SiGe quantum dots applicable to general heterostructures, revealing significant renormalization effects in "Wiggle Well" structures and a giant -factor suppression driven by spin-valley coupling at low valley splitting locations.
This paper demonstrates that a 1-degree twist in NbSe2 superconducting diodes achieves an optimal 27.6% rectification efficiency under magnetic fields, revealing that intermediate rather than maximal nonreciprocity is crucial for preserving qubit anharmonicity and enabling high-fidelity quantum circuits.
