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…
