This paper demonstrates an on-chip cavity electro-acoustic platform using lithium niobate phononic crystal resonators that leverages electrical modulation to emulate atomic-like transitions, enabling the observation of quantum phenomena such as Autler-Townes splitting and Rabi oscillations, as well as achieving tunable non-reciprocal frequency conversion.
This paper investigates the decay dynamics of a transmon qubit coupled to a broadband one-dimensional cavity, using resolvent formalism to identify a transition from Markovian to non-Markovian regimes based on coupling strength and demonstrating how two-photon decay channels significantly influence the system's energy-dependent resonance widths.
This study demonstrates the spectroscopy of up to eight interacting spins in a 2x4 germanium quantum dot array using Ramsey interferometry and adiabatic mapping, successfully reconstructing the many-body energy spectrum and observing the crossover from localization to a chaotic phase.
This paper introduces an efficient real-space formulation of the Chern number via a supercell framework that coincides with the Bott index, using it to demonstrate that topological phases in a disordered Chern insulator remain robust against polarized disorder but undergo a transition to a trivial phase under normal disorder.
This paper investigates ballistic electron transport in AB-stacked bilayer graphene, revealing that perfect transmission at discrete energies arises from mode-selective phase-matching cavity resonances within electrostatic barriers, a phenomenon distinct from Fabry-Perot interference and decoupled channel activation.
This paper establishes a direct analytical link between Raman circular dichroism and magnon Berry curvature by deriving the Fleury-Loudon Raman vertex from a light-matter coupling expansion, thereby providing a general route to experimentally probe the quantum geometry of charge-neutral magnons in topological systems like monolayer CrI.
This paper demonstrates that rhombohedral graphene serves as a promising platform for exploring rich nonlinear optical phenomena, specifically showing how the linear scaling of chiral Bloch state winding with layer number and interaction-induced valley splitting govern the system's high-harmonic generation and circular dichroism.
This study demonstrates that natural van der Waals oxide -VO enables tunable, unidirectional polariton canalization without complex fabrication, offering a promising platform for nanoscale light control through its intrinsic in-plane hyperbolicity.
This paper introduces a polymer-free method for assembling 2D material heterostructures using temperature-controlled muscovite crystals, which enables deterministic, contamination-free transfer and stacking to facilitate the automated fabrication of pristine van der Waals devices.
This paper theoretically demonstrates that strain-induced axial pseudomagnetic fields, by aligning with Berry curvature and orbital magnetic moments on gapped nodal ring Fermi surfaces, generate unique, angle-independent contributions to magnetoelectric conductivity, including a strain-insensitive component that serves as a robust internal reference for identifying topological transport signatures.
