Mean first passage times reconstruct the slowest relaxations in potential energy landscapes of nanoclusters
Teruaki Okushima, Tomoaki Niiyama, Kensuke S. Ikeda +1
Relaxation modes are the collective modes in which all probability deviations from equilibrium states decay with the same relaxation rates. In contrast, a first passage time is the…
Changes of graph structure of transition probability matrices indicate the slowest kinetic relaxations
Teruaki Okushima, Tomoaki Niiyama, Kensuke S. Ikeda +1
Graphs of the most probable transitions for a transition probability matrix, , i.e., the time evolution matrix of the transition rate matrix over a finite time interval…
Slowest kinetic modes revealed by metabasin renormalization
Teruaki Okushima, Tomoaki Niiyama, Kensuke S. Ikeda +1
Understanding the slowest relaxations of complex systems, such as relaxation of glass-forming materials, diffusion in nanoclusters, and folding of biomolecules, is important for ph…
Instanton-noninstanton transition in nonintegrable tunneling processes: A renormalized perturbation approach
Akira Shudo, Yasutaka Hanada, Teruaki Okushima +1
The instanton-noninstanton (I-NI) transition in the tunneling process, which has been numerically observed in classically nonintegrable quantum maps, can be described by a perturba…
DNA as a one-dimensional chiral material. II. Dynamics of the structural transition between B form and Z form
Teruaki Okushima, Hiroshi Kuratsuji
We analyze the dynamics of structural transitions between normal right-handed B form and unusual left-handed Z form for a linear DNA molecule. The dynamics under the external torqu…
DNA as a one-dimensional chiral material: Application to the structural transition between B form and Z form
Teruaki Okushima, Hiroshi Kuratsuji
A dynamical model is presented for chiral change in DNA molecules. The model is an extension of the conventional elastic model which incorporates the structure of base pairs and us…
Quantum Optics in Dispersive and Absorptive Media
Akira Shimizu, Teruaki Okushima, Kazuki Koshino
Using microscopic models in which both photons and excitons are treated as microscopic degrees of freedom, we discuss polaritons of two cases: One is the case when excitonic parame…
