Open quantum systems (OQSs) cannot always be described with the Markov approximation,
which requires a large separation of system and environment time scales. An overview is …

Photosynthesis is a highly optimized process from which valuable lessons can be learned
about the operating principles in nature. Its primary steps involve energy transport operating …

Quantum‐classical formulations of reactive flux correlation functions require the partial Weyl–
Wigner transform of the thermalized flux operator, whose numerical evaluation is unstable …

We use the quantum–classical path integral (QCPI) methodology to report numerically exact,
fully quantum mechanical results for the exciton-vibration dynamics in the …

An open quantum system refers to a system that is further coupled to a bath system
consisting of surrounding radiation fields, atoms, molecules, or proteins. The bath system is …

A contemporary review on the behavior of driven tunneling in quantum systems is
presented. Diverse phenomena, such as control of tunneling, higher harmonic generation …

Studies of the dynamics of open quantum systems are limited by the large Hilbert space of
typical environments, which is too large to be treated exactly. In some cases, approximate …

The flux formulation of reaction rate theory is recast in terms of the expectation value of the
reactive flux with an initial condition that corresponds to a non-equilibrium, factorized …

Quantum biology is an emerging field of research that concerns itself with the experimental
and theoretical exploration of non-trivial quantum phenomena in biological systems. In this …

Discoveries in quantum materials, which are characterized by the strongly quantum-
mechanical nature of electrons and atoms, have revealed exotic properties that arise from …
