Crosscap States in Integrable Field Theories and Spin Chains
We study crosscap states in integrable field theories and spin chains in $1+1$ dimensions. We derive an exact formula for overlaps between the crosscap state and any excited state in integrable field theories with diagonal scattering. We then compute the crosscap entropy, i.e. the overlap for the gr...
