Open quantum dynamics theory on the basis of periodical system-bath model for discrete Wigner function
Yuki Iwamoto, Yoshitaka Tanimura
Discretizing a distribution function in a phase space for an efficient quantum dynamics simulation is a non-trivial challenge, in particular for a case that a system is further cou…

Open Quantum Dynamics of a Three-Dimensional Rotor Calculated Using a Rotationally Invariant System-Bath Hamiltonian: Linear and Two-Dimensional Rotational Spectra
Yuki Iwamoto, Yoshitaka Tanimura
We consider a rotationally invariant system-bath (RISB) model in three-dimensional space that is described by a linear-rigid rotor independently coupled to three sets of harmonic-o…

Linear Absorption Spectrum of a Quantum Two-Dimensional Rotator Calculated Using a Rotationally Invariant System-Bath Hamiltonian
Yuki Iwamoto, Yoshitaka Tanimura
We consider a two-dimensional rigid rotator system coupled to a two-dimensional heat bath. The Caldeira-Leggett (Brownian) model for the rotator and the spin-Boson model have been…
