Time-Reversal Symmetry Breaking in Semiclassical Two-Point Level Correlator

抄録

We apply the semiclassical theory to the two-point level correlator in the crossover regime between time-reversal and non-time-reversal symmetry for a system which exhibits chaos in the classical limit. The diffuson and Cooperon contributions are explicitly derived semiclassically. The expression of the off-diagonal part is different from the previous results by several authors.
