This paper investigates the quantum mechanical version of the Prandtl-Tomlinson model for nanoscale friction, revealing that Landau-Zener tunneling significantly reduces frictional dissipation compared to classical motion and providing guidelines for interpreting experimental data by analyzing the interplay between velocity, interaction strength, and temperature.
This paper demonstrates that an asymmetrically driven hybrid magnon-photon system can function as a highly tunable quantum heat rectifier, where strong external driving of the magnonic subsystem in the weak hybridization regime enables precise control over both the magnitude and direction of thermal currents.
This paper demonstrates that waveguide quantum electrodynamics in aperiodic Fibonacci photonic arrays enables decoherence-free, coherent interactions between quantum emitters by engineering atom-photon bound states that inherit the deterministic complexity and multifractal properties of the underlying Fibonacci-Lucas structure.
This paper establishes a theoretical framework for one-dimensional nonsymmorphic Kramers degenerate systems with and topological classifications, extends winding-number invariants to these four-band models, and validates their topological phases and robust zero-energy modes through proposed topolectric circuit realizations and disorder analysis.
This paper predicts that superconductor/antiferromagnet/superconductor heterostructures enable ultrastrong magnon-photon coupling at terahertz frequencies, where magnetic fields tune the interaction between one or both magnon modes and photons to create highly tunable magnon-polaritons with group velocities reaching several tenths of the speed of light.
This study demonstrates that selective random defects on a honeycomb lattice can induce topological transitions or smoothly connect topological phases by modulating hopping amplitudes, offering a new strategy for controlling the spectral and topological properties of electronic systems.
This study reveals that while the body-centered tetragonal phase is thermodynamically stable for small zinc oxide nanoparticles, the atom-by-atom deposition process drives a phase transition to the more stable wurtzite structure through a specific ion redistribution that compensates for emerging polar facets.
This paper establishes a comprehensive group-theory framework for assigning symmetry labels and total crystal angular momentum to excitonic states, enabling the derivation of selection rules, conservation laws, and enhanced computational efficiency for the Bethe-Salpeter equation, as demonstrated through applications to LiF, monolayer MoSe2, and bulk hBN.
This paper establishes a unified framework connecting non-Hermitian Zeeman quantum geometry, local Dirac-node topology, and measurable transport signatures by demonstrating that the Zeeman quantum geometric tensor decomposes into normal and anomalous sectors, where the latter reveals a novel curvature-flux representation of local topology and distinct linear response scalings.
This paper establishes a geometric characterization of the non-Hermitian skin effect by demonstrating that the localization length scale is encoded in the quantum metric derived solely from right eigenstates, which exhibits power-law divergences at gapless points and discontinuities signaling generalized Brillouin zone cusps.
