Wave packet landscape in open quantum systems
Kang Xu, Miao-Miao Yi, Zi-Hong Yan +1
We formulate a landscape theory for the long-time wave packet spreading of free and harmonically trapped particles with quantum fluctuations and its related dissipation. We show th…

Third Quantization for Order Parameters (II): Local Field Quantization in Superconducting Quantum Circuits
Miao-Miao Yi, Guo-Jian Qiao, Xin Yue +1
The quantization of superconducting transmission-line resonators is usually introduced phenomenologically by modeling the resonator as an effective LC circuit and imposing canonica…

Third Quantization for Order Parameter (I): BCS-BEC crossover with macroscopically coherent state
Guo-Jian Qiao, Miao-Miao Yi, Xin Yue +1
We revisit the quantization of the order parameter, which we refer to as third quantization, from the perspective of the commutation relation between the phase operator of the orde…
