Quantum evolution speed in the finite-temperature bosonic environment
Jun-Qing Cheng, Guo-Qing Zhang, Jing-Bo Xu
We investigate the quantum evolution speed of a qubit in two kinds of finite-temperature environments. The first environment is a bosonic bath with Ohmic-like spectrum. It is found…

Coherent dynamics of a qubit-oscillator system in a noisy environment
Wei Wu, Jun-Qing Cheng
We investigate the non-Markovian dynamics of a qubit-oscillator system embedded in a noisy environment by employing the hierarchical equations of motion approach. It is found that…
