Time-dependent approaches to open quantum systems
M. Tokieda, K. Hagino
Couplings of a system to other degrees of freedom (that is, environmental degrees of freedom) lead to energy dissipation when the number of environmental degrees of freedom is larg…

A new approach for open quantum systems based on a phonon number representation of a harmonic oscillator bath
M. Tokieda, K. Hagino
To investigate a system coupled to a harmonic oscillator bath, we propose a new approach based on a phonon number representation of the bath. Compared to the method of the hierarch…
