Interfaces of correlated electron systems: Proposed mechanism for colossal electroresistance
Takashi Oka, Naoto Nagaosa
Mott's metal-insulator transition at an interface due to band bending is studied by the density matrix renormalization group (DMRG). We show that the result can be recovered by a s…

Nonlinear Transport in One-Dimensional Mott Insulator in Strong Electric Fields
Takashi Oka, Ryotaro Arita, Hideo Aoki
Time-dependent Schroedinger's equation is integrated for a one-dimensional strongly-correlated electron system driven by large electric fields. For larger electric fields, many-bod…

Ground-State Decay Rate for the Zener Breakdown in Band and Mott Insulators
Takashi Oka, Hideo Aoki
Non-linear transport of electrons in strong electric fields, as typified by dielectric breakdown, is re-formulated in terms of the ground-state decay rate originally studied by Sch…
