Environmental Quantum States Trigger Emission in Nonlinear Photonics
Jia-Qi Li, Xin Wang
Light-matter interactions are traditionally governed by two fundamental paradigms: spontaneous and stimulated radiation. However, in nonlinear multi-photon regimes, these classical…
Heat dissipation in marginally stable linear time-delayed Langevin systems
Xin Wang
The thermodynamic properties of time-delayed dynamics remain largely unexplored, especially for systems that exhibit asymptotically non-stationary behavior. Here, we investigate he…
Characteristic oscillations in frequency-resolved heat dissipation of linear time-delayed Langevin systems: Approach from the violation of the fluctuation-response relation
Xin Wang, Ruicheng Bao, Naruo Ohga
Time-delayed effects are widely present in nature, often accompanied by distinctive nonequilibrium features, such as negative apparent heat dissipation. To elucidate detailed struc…
Selective band interaction and long-range hopping in a structured environment with giant atoms
Ying Xia, Jia-Qi Li, Xin Wang
Giant atoms, which couple to the environment at multiple discrete points, exhibit various nontrivial phenomena in quantum optics due to their nonlocal couplings. In this study, we…
Supercorrelated decay in a quasiperiodic nonlinear waveguide: From Markovian to non-Markovian transitions
Jia-Qi Li, Tian-Yu Zhou, Xin Wang
Mobility edges (MEs) are critical boundaries in disordered quantum systems that separate localized from extended states, significantly affecting transport properties and phase tran…
