Electronic properties of alkali-metal loaded zeolites -- a "supercrystal" Mott insulator
Ryotaro Arita, Takashi Miyake, Takao Kotani +5
First-principles band calculations are performed for the first time for an open-structured zeolite (LTA) with guest atoms (potassium) introduced in their cages. A surprisingly simp…

Breakdown of a Mott insulator -- non-adiabatic tunneling mechanism
Takashi Oka, Ryotaro Arita, Hideo Aoki
Time-dependent nonequilibrium properties of a strongly correlated electron system driven by large electric fields is obtained by means of solving the time-dependent Schrödinger equ…
