Path integral approach to heat in quantum thermodynamics
Ken Funo, H. T. Quan
We study the heat statistics of a quantum Brownian motion described by the Caldeira-Leggett model. By using the path integral approach, we introduce a novel concept of the quantum…
Quantum Fluctuation Theorems
Ken Funo, Masahito Ueda, Takahiro Sagawa
Recent advances in experimental techniques allow one to measure and control systems at the level of single molecules and atoms. Here gaining information about fluctuating thermodyn…
Speed Limit for Classical Stochastic Processes
Naoto Shiraishi, Ken Funo, Keiji Saito
Speed limit for classical stochastic Markov processes with discrete states is studied. We find that a trade-off inequality exists between the speed of the state transformation and…
Path integral approach to quantum thermodynamics
Ken Funo, H. T. Quan
Work belongs to the most basic notions in thermodynamics but it is not well understood in quantum systems, especially in open quantum systems. By introducing a novel concept of wor…
Work fluctuation and total entropy production in nonequilibrium processes
Ken Funo, Tomohiro Shitara, Masahito Ueda
Work fluctuation and total entropy production play crucial roles in small thermodynamic systems subject to large thermal fluctuations. We investigate a trade-off relation between t…
