Open Quantum Systems Driven by Chirped Pulses: Quantized versus Semiclassical Fields and the Validity of the Rotating-Wave Approximation
Justin Zhengjie Tan, Frank GroÃmann, Yiying Yan +2
Population transfer via chirped rapid adiabatic passage is studied using open quantum and semiclassical models, with and without the rotating-wave approximation. A time-dependent v…
Dynamical multipartite entanglement in a generalized Tavis-Cummings model with XY spin interaction
Yuguo Su, Zhijie Sun, Yiying Yan +5
Multipartite entanglement is a long-term pursuit in the resource theory, offering a potential resource for quantum metrology. Here, we present the dynamical multipartite entangleme…
Hamiltonian non-Hermicity: accurate dynamics with the multiple Davydov D Ansätze
L. Zhang, K. Shen, Y. Yan +3
We examine the applicability of the numerically accurate method of time dependent variation with multiple Davydov Ansatze (mDA) to non-Hermitian systems. Three systems of interest…
Variational approach to light-matter interaction: Bridging quantum and semiclassical limits
Yiying Yan, Zhiguo Lü, JunYan Luo
We present a time-dependent variational approach with the multiple Davydov trial state to simulate the dynamics of light-matter systems when the field is in a coherent state…
