This paper demonstrates that in non-Hermitian impurity scattering, late-time dynamics are governed by "dynamical poles" derived from the analytic continuation of the Green's function rather than static bound states, revealing a fundamental breakdown of the Hermitian correspondence where isolated exponential signals uniquely identify bound states.
This paper demonstrates a violation of the Wiedemann-Franz law in a GaAs hydrodynamic mesoscopic channel by using micrometer-resolution photoluminescence thermometry to observe the distinct relaxation of electric and thermal currents, particularly highlighting the critical role of narrow constrictions in this phenomenon.
This paper demonstrates that in hybrid systems of quantum dots coupled to a finite-length superconductor, the existence and number of Poor Man's Majorana modes are highly sensitive to the superconductor's length, oscillating with the Fermi wavelength and precluding the formation of perfectly localized end modes, thereby necessitating a redefined "sweet spot" for practical applications.
This study demonstrates that the honeycomb CuSe monolayer on Cu(111) undergoes a reversible structural transition between stripe and hole phases, which is driven by the interplay of selenium coverage and annealing temperature.
Using tensor network methods, this study demonstrates that bosonic topological edge modes persist in a ladder quantum paramagnet despite strong many-body interactions, resolving the discrepancy between theoretical predictions and experimental observations by showing these signatures survive even when non-interacting quasi-particle theories break down.
This paper proposes using optically hyperpolarized levitated solids, such as pentacene-doped naphthalene, to enable advanced applications like multi-spin matter-wave interferometry for testing objective collapse models and ultra-high-frequency magic angle spinning, while overcoming limitations inherent to traditional solid-state spin defect systems.
This paper demonstrates that the radiative and nonradiative decay rates of a fluorescent molecule can be continuously and reversibly tuned by up to two orders of magnitude through electrical shifting of a Fano resonance-induced transparency, offering significant potential for integrated quantum technologies and advanced imaging applications.
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 proposes rhombohedral graphite junctions as a tunable platform where sliding the crystals relative to one another enables a continuous transition between topologically trivial and non-trivial electronic phases by manipulating the interfacial atomic stacking symmetry.
