Energy Landscape of Charge Excitations in Boundary Region between Dimer-Mott and Charge Order State in Molecular Solids

Abstract

A possible theoretical scheme is proposed for the unified description of charge excitations with $10^{10}$ orders of magnitude difference in energy [from optical($\sim$eV) down to dielectric anomalies (10KHz$\sim 10^{-10}$eV)] based on a simple and single model.
