Effect of quantum coherence on Landauer's principle

Kazunari Hashimoto, Chikako Uchiyama

Quantum Landauer's principle provides a fundamental lower bound for energy dissipation occurred with information erasure in the quantum regime. While most studies have related the…

Lower bounds for the mean dissipated heat in an open quantum system

Kazunari Hashimoto, Bassano Vacchini, Chikako Uchiyama

Landauer's principle provides a perspective on the physical meaning of information as well as on the minimum working cost of information processing. Whereas most studies have relat…

Non-Markovian effect on quantum Otto engine: -Role of system--reservoir interaction-

Yuji Shirai, Kazunari Hashimoto, Ryuta Tezuka +2

We study a limit cycle of a quantum Otto engine whose each cycle consists of two finite-time quantum isochoric (heating or cooling) processes and two quantum adiabatic work-extract…

Nonadiabaticity in spin pumping under relaxation

Kazunari Hashimoto, Gen Tatara, Chikako Uchiyama

Using a minimum model consisting of a magnetic quantum dot and an electron lead, we investigate spin pumping by its precessing magnetization. Focusing on the "adiabaticity", which…
