Lower and upper bounds of quantum battery power in multiple central spin systems
Li Peng, Wen-Bin He, Stefano Chesi +2
We study the energy transfer process in quantum battery systems consisting of multiple central spins and bath spins. Here with "quantum battery" we refer to the central spins, wher…

Exact quantum dynamics of XXZ central spin problems
Wen-Bin He, Stefano Chesi, Hai-Qing Lin +1
We obtain analytically close forms of benchmark quantum dynamics of the collapse and revival (CR), reduced density matrix, Von Neumann entropy, and fidelity for the XXZ central spi…
