Direct regular-to-chaotic tunneling rates using the fictitious integrable system approach
Direct regular-to-chaotic tunneling rates fictitious integrable system approach
2010/10/21
We review the fictitious integrable system approach which predicts dynamical tunneling rates
from regular states to the chaotic region in systems with a mixed phase space. It is based on the introduc...
Efficient creation of maximally entangled states by modulation of tunneling rates
entangled states modulation of tunneling rates
2010/4/16
For systems described by the two-site Bose-Hubbard Hamiltonian, we show that a sinusoidal modulation of the tunneling matrix element assists higher-order co-tunneling processes. Using this mechanism, ...
