Landau-Zener tunneling problem for Bloch states
Ryuji Takahashi, Naoyuki Sugimoto
We study the Landau-Zener tunneling problem for particles bound in periodic lattice insulators. To this end, we construct the path integral based on the Bloch and Wannier functions…

Current control of systems with a Peierls distortion by magnetic field
Ryuji Takahashi, Naoyuki Sugimoto
We study the tunneling phenomenon of a ladder system with a Peierls distortion in a magnetic flux, and the response of electrons the insulator is investigated when the tunneling cu…

Semiclassical Lattice effects on interband tunneling of a two-state system
Ryuji Takahashi, Naoyuki Sugimoto
Previously, we have shown that the transition probability of the Landau-Zener problem in periodic lattice systems becomes large by taking into account the nonlinearity of the energ…
