概要
- 論文の詳細を見る
Thermodynamics and transport properties or resistance-shunted Josephson junctions are studied theoretically in the tight binding limit E_C/E_J≪1, where E_C and E_J are a charging energy model, weak coupling region K=R_Q/R≪1 is analytically studied, where R and R_Q=h/(2e)^2 are a shunt resistance and the quantum resistance. In addition to an effective bandwidth 2hΔ_<eff> we find that this multi-level system genuinely has a novel crossover at lower energy KhΔ_<eff> below which the density of states becomes strongly degenerate. These two energy scales control the linear DC responses, optical response, and nonlinear I-V characteristics. The lower energy crossover indicates the existence of a new class of strongly-correlated phenomena beyond the framework of the Kondo problem.
