This paper investigates the optical properties of CuO-metal core-shell nanostructures containing Rydberg excitons by employing the Real Density Matrix Approach to calculate exciton energies and their dependence on system geometry and dimensionality across various size limits.
This paper employs -convergence to demonstrate that rigid polycrystalline structures in charge-dependent hard-sphere ionic systems emerge as low-energy configurations, yielding a continuum theory where anisotropic interfacial energy concentrates at grain boundaries determined by misorientation, translation misfit, and interface normal.
This study demonstrates that epitaxial SrVO₃ thin films exhibit magnetoresistance signatures consistent with the orbital Hall effect, supported by density functional theory calculations and diffusive modeling that reveal a predominantly orbital response with a large orbital-to-spin Hall conductivity ratio, establishing narrow-band d¹ metallic oxides as a promising platform for orbital transport.
This paper investigates Floquet-spin-orbit compensation in the - lattice, revealing how tuning the interplay between circularly polarized light and intrinsic spin-orbit coupling induces distinct band-degeneracy conditions that enable the inverse determination of the lattice parameter through intrinsic transverse thermoelectric responses.
This paper utilizes non-equilibrium Green's functions to demonstrate that electrons tunneling through a square lattice in a magnetic field exhibit robust, unity transmission plateaus via topologically protected boundary modes, offering promising applications for current standards, clocks, and thermoelectric devices.
By representing the cavity field in a large-photon-number phase basis, this paper establishes a rigorous, gauge-invariant correspondence between fully quantized light-matter interactions and classical Floquet engineering, demonstrating that the latter emerges directly from the former without mean-field approximations while encoding entanglement in matter-harmonic correlations.
This paper develops a microscopic many-body theory demonstrating that the quasi-one-dimensional character of excitons in mono- and bilayer CrSBr leads to strongly anisotropic scattering and direction-dependent diffusion coefficients due to exciton-phonon and exciton-magnon interactions, while identifying distinct temperature dependencies arising from specific scattering processes.
This paper investigates charge and thermoelectric transport in monolayer graphene with dilute non-Hermitian impurities, demonstrating that while gain enhances carrier lifetime and thermoelectric performance, absorption suppresses them, thereby establishing non-Hermitian scattering as a tunable mechanism for controlling graphene's energy-dependent relaxation and thermoelectric response.
This paper establishes a universal duality between Hermitian level statistics and non-Hermitian eigenvector overlaps by deriving analytical expressions for these overlaps across ten symmetry classes using fermionic replica nonlinear models, a result supported by numerical calculations in various physical models.
This paper demonstrates the initialization of high-frequency mechanical modes in a high-overtone bulk acoustic wave resonator to near-quantum ground states with extremely low excited-state populations, thereby establishing a versatile platform for quantum sensing and placing stringent constraints on new physics phenomena such as high-frequency gravitational waves, ultra-light dark matter, and wavefunction collapse mechanisms.
