Dynamics of scalar fields in an expanding/contracting cosmos at finite temperature
Hui Xu, Lei Ming, Yeuk-Kwan E. Cheung
This paper extends the study of the quantum dissipative effects of a cosmological scalar field by taking into account the cosmic expansion and contraction. Cheung, Drewes, Kang and…
On-Shell Gauge Invariant Three-Point Amplitudes
Zhengdi Sun, Hui Xu, Yeuk-Kwan E. Cheung
Assuming locality, Lorentz invariance and parity conservation we obtain a set of differential equations governing the 3-point interactions of massless bosons, which in turn determi…
Signature of non-Markovianity in time-resolved energy transfer
Junjie Liu, Hui Xu, Changqin Wu
We explore signatures of the non-Markovianity in the time-resolved energy transfer processes for quantum open systems. Focusing on typical systems such as the exact solvable damped…
Nonequilibrium spin-boson model: from weak to strong coupling
Junjie Liu, Hui Xu, Baowen Li +1
We present a general theory to explore energy transfer in nonequilibrium spin-boson models within the framework of nonequilibrium Green's function (NEGF). In contrast to convention…
Green's functions for spin boson systems: Beyond conventional perturbation theories
Junjie Liu, Hui Xu, Changqin Wu
Unraveling general properties of Green's functions of quantum dissipative systems is of both experimental relevance and theoretical interest. Here, we study the spin-boson model as…
