Particle-Time Duality in the Kicked Ising Chain II: Applications to the Spectrum
Particle-Time Duality in the Kicked Ising Chain II: Applications to the Spectrum
Previously, we demonstrated that the dynamics of kicked spin chains possess a remarkable duality property. The trace of the unitary evolution operator for $N$ spins at time $T$ is related to one of a non-unitary evolution operator for $T$ spins at time $N$. Using this duality relation we obtain the …
