Abstract:
We investigate the off-diagonal sector of eigenstate thermalization using
both local and non-local probes in 2-dimensional conformal field theories. A
novel analysis of the asymptotics of OPE coefficients via the modular bootstrap
is performed to extract the behaviour of the off-diagonal matrix elements. We
also probe this sector using semi-classical heavy-light Virasoro blocks. The
results demonstrate signatures of thermality and confirms the entropic
suppression of the off-diagonal elements as necessitated by the eigenstate
thermalization hypothesis.
