Fast-forward approach to adiabatic quantum dynamics of regular spin clusters: nature of geometry-dependent driving interactions

Autor: Iwan Setiawan, S. Avazbaev, Katsuhiro Nakamura, Bobby E. Gunara

The fast forward scheme of adiabatic quantum dynamics is applied to finite regular spin clusters with various geometries and the nature of driving interactions is elucidated. The fast forward is the quasi-adiabatic dynamics guaranteed by regularizati

Fast forward of adiabatic control of tunneling states

Autor: S. Avazbaev, Shumpei Masuda, Katsuhiro Nakamura, Anvar Khujakulov

By developing the preceding work on the fast forward of transient phenomena of quantum tunneling by Khujakulov and Nakamura (Phys. Rev. {\bf A 93}, 022101 (2016) ), we propose a scheme of the exact fast forward of adiabatic control of stationary tunn

Publikováno v: Physical Review A. 93

The semiclassical convergent close-coupling approach to ion-atom collisions has been extended to include electron-transfer channels. The approach has been applied to study the excitation and the electron-capture processes in proton-hydrogen collision

Publikováno v: Наносистемы: физика, химия, математика.

The motion of a quantum particle in a time-dependent circular billiard is studied on the basis of the Schrodinger equation with time-dependent boundary conditions. The cases of monotonically expanding (contracting), non-harmonically, harmonically bre

We show, using quasi-exact numerical simulations, that Anderson localization of one-dimensional particles in a disordered potential survives in the presence of attractive interaction between particles. The localization length of the composite particl
