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 …

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

We propose a method to study the thermodynamic behaviour of small systems beyond the
weak coupling and Markovian approximation, which is different in spirit from conventional …

We present an overview of recent advances in the study of energy dynamics and
mechanisms for energy conversion in qubit systems with special focus on realizations in …

We consider a quantum system strongly coupled to multiple heat baths at different
temperatures. Quantum heat transport phenomena in this system are investigated using two …

We use the fundamental nonequilibrium steady-state fluctuation symmetry and derive a
condition on the validity of the thermodynamic uncertainty relation (TUR) in thermal transport …

Entropy production plays a fundamental role in nonequilibrium thermodynamics to quantify
the irreversibility of open systems. Its positivity can be ensured for a wide class of setups, but …

We review studies of vibrational energy transfer in a molecular junction geometry, consisting
of a molecule bridging two heat reservoirs, solids or large chemical compounds. This setup …

We review a theory for coupled many-nonlinear oscillator systems that describes quantum
ergodicity and energy flow in molecules. The theory exploits the isomorphism between …
