Below are the most recent papers in this dynamic area of condensed matter physics, ready for you to explore.
This study demonstrates that while quantum dot superlattices exhibit delocalized excitonic states, electronic delocalization does not necessarily lead to cooperative emission due to disorder-induced inhomogeneous broadening and exciton-state mixing that prevent macroscopic phase coherence.
This tutorial paper elucidates how relative motion between interacting magnonic systems generates an emergent Doppler energy scale that drives nonequilibrium phenomena, ranging from motion-induced magnon transport to parametric instabilities and spontaneous pair creation, thereby providing a unifying framework for understanding dynamics in moving quantum systems.
This paper proposes and validates a geometric approach to reservoir computing that engineers extrinsic memory in zero-memory quantum dot systems by utilizing multidimensional input nodes to create spatial degrees of freedom, thereby enabling high-performance chaotic prediction and nonlinear transformation tasks through the formation of topologically stable hysteresis loops in quantum Hilbert space.
This paper resolves the conceptual ambiguity regarding intrinsic second-order dc nonlinear conductivity by establishing a gauge-consistent density-matrix theory that proves the equivalence of length and velocity gauges, demonstrating that the adiabatic response is a purely Fermi-surface quantum geometric contribution determined by the band-normalized quantum metric, which vanishes in fully gapped insulators.
This paper investigates heat rectification in an asymmetrically coupled quantum two-level system using a tensor-network approach, revealing a universal power-law scaling of the rectification ratio in the strongly correlated infrared regime below the Kondo temperature.
This paper introduces a novel, scalable method using a conventional Atomic Force Microscope (AFM) with indentation and "hard tapping" to efficiently nucleate, manipulate, and dynamically image graphene auto-kirigami ribbons, overcoming the limitations of specialized multi-axial systems and enabling their potential application in NEMS devices.
This review summarizes recent advances establishing GaAs/AlAs acoustic nanocavities, particularly DBR-based micropillar resonators, as a versatile and scalable platform for coherent GHz-THz phonon engineering by leveraging their mature growth, strong optophononic coupling, and 3D confinement capabilities for applications in hybrid quantum systems and integrated phononic circuits.
This study reports the discovery of exceptionally large anisotropic magnetoresistance and a pronounced planar Hall effect in YBa2Cu3O7-x near its superconducting transition, providing clear evidence of strong spin-orbit coupling in a material class previously thought to lack such interactions.
This study identifies a new plasmon-like mode in PdTe below 100 K through temperature-dependent Raman scattering, confirming its electronic origin via congruent theoretical modeling and phenomenological analysis of the linear frequency dependence of the Raman relaxation rate.
The paper predicts that adding extra terminals to photovoltaic cells to selectively extract "hot" carriers before they relax can boost power output by 20–40% compared to optimal two-terminal designs, a principle also applicable to multi-terminal thermoelectrics.
