Lian-suo Wei,Long-yu Ma,Shen-hao Huangimpossible to give a comprehensive review of all relevant publications. This is particularly the case for the dynamics of multilevel quantum systems, which usually is just a technical aspect and not the main concern of research papers and textbooks dedicated mostly to physical phenomena, rather than to the technical details of their description.

Siyu Wang,Bo Yang,Zhiwen Yu,Shuaibing LuThe most studied manifestation of entanglement is mixing of quantum states, which results from interaction of an open quantum system with the environment. The quantum state of the open system is a statistical mixture of pure quantum states characterized by the density matrix.

Soluble Time-Dependent Systems,We now consider quantum systems with time-dependent Hamiltonians. The formal expression for the evolution operator for such systems is given by the time-ordered exponent of the integral of the corresponding Hamiltonian, . which simply involves the sequential application of infinitesimal evolution operators . with instantaneous Hamiltonians.
