Recent years have seen tremendous progress in the theoretical understanding of quantum
systems driven dissipatively by coupling to different baths at their edges. This was possible …

Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

While several numerical techniques are available for predicting the dynamics of non-
Markovian open quantum systems, most struggle with simulations for very long memory and …

The simulations of spectroscopy and quantum dynamics are of vital importance to the
understanding of the electronic processes in complex systems, including the …

We present the reaction-coordinate polaron-transform (RCPT) framework for generating
effective-Hamiltonian models to treat nonequilibrium open quantum systems at strong …

Quantum systems are inherently open and susceptible to environmental noise, which can
have both detrimental and beneficial effects on their dynamics. This phenomenon has been …

Electron transfer is at the heart of many fundamental physical, chemical, and biochemical
processes essential for life. The exact simulation of these reactions is often hindered by the …

When a quantum system couples strongly to multiple baths, then it is generally no longer
possible to describe the resulting system dynamics by simply adding the individual effects of …

A general thermodynamic framework is presented for open quantum systems in fixed contact
with a thermal reservoir. The first and second law are obtained for arbitrary system-reservoir …

A quantum system weakly coupled to a zero-temperature environment will relax, via
spontaneous emission, to its ground-state. However, when the coupling to the environment …
