Entanglement Hamiltonian and effective temperature of non-Hermitian quantum spin ladders
Pei-Yun Yang, Yu-Chin Tzeng
Quantum entanglement plays a crucial role not only in understanding Hermitian many-body systems but also in offering valuable insights into non-Hermitian quantum systems. In this p…

Quantum Effects in Chemical Reactions under Polaritonic Vibrational Strong Coupling
Peiyun Yang, Jianshu Cao
The electromagnetic field in an optical cavity can dramatically modify and even control chemical reactivity via vibrational strong coupling (VSC). Since the typical vibration and c…

Exact dynamics of the homogeneous two-qubit central spin model with the spin bath prepared in superpositions of symmetric Dicke states
Zejiang Li, Pei Yang, Wen-Long You +1
We obtain exact dynamics of a two-qubit central spin model (CSM) consisting of two interacting qubits homogeneously coupled to a spin bath via the -type coupling, with the bat…
