Exact dynamics of first-order system-bath coherence in bilinear bosonic models
Yang-Yang Xie, Song-Lin Wu, Paul Brumer +2
We investigate the exact dynamics of first-order system--bath coherence induced by excitation exchange in bilinear bosonic models. By solving the linear Heisenberg equations, we ob…
Coherent Control of Energy Transport at Room Temperature in a Noisy Bath
Davinder Singh, Paul Brumer
Coherent control of energy transport in a non-equilibrium steady-state (NESS) in a reaction-center-connected donor-acceptor pair is proposed. The pigments are considered to be cont…
Steady-State Coherences under Partial Collective non-Markovian Decoherence
S. L. Wu, W. Ma, Zhao-Ming Wang +2
Steady-state coherence in open quantum systems is crucial for quantum technologies, yet its behavior is not fully understood due to the interplay between collective and individual…
Mixed State Entanglement Via the Cauchy-Schwarz Inequality
Nishaant Jacobus, Paul Brumer, Chern Chuang
The entanglement properties of mixed states are of great importance in the study of open quantum systems and quantum information science, but commonly used entanglement measures, s…
Parametric Hypersensitivity and Transport in the Steady-State Open-System Holstein Model
Nishaant Jacobus, Paul Brumer, Chern Chuang
We demonstrate that the nonequilibrium steady state (NESS) of an open-system Holstein model with linear bias displays extreme sensitivity to the closed system parameters. This sens…
