Polynomial complexity of open quantum system problems
Chong Chen, Ren-Bao Liu
Open quantum systems (OQS's) are ubiquitous in non-equilibrium quantum dynamics and in quantum science and technology. Solving the dynamics of an OQS in a quantum many-body bath ha…

Structures in higher-order quantum correlations due to non-spatial symmetries
Li Sun, Chong Chen, Ren-Bao Liu
Quantum nonlinear spectroscopy (QNS) via a quantum sensor can access types of -th order contour-time-ordered correlations (CTOCs) arising from different orderings of q…
