Query: Corrections to scaling for block entanglement in massive spin-chains   We consider the Renyi entropies S_n in one-dimensional massive integrable
models diagonalizable by means of corner transfer matrices (as Heisenberg and
Ising spin chains). By means of explicit examples and using the relation of
corner transfer matrix with the Virasoro algebra, we show that close to a
conformal invariant critical point, when the correlation length xi is finite
but large, the corrections to the scaling are of the unusual form xi^(-x/n),
with x the dimension of a relevant operator in the conformal theory. This is
reminiscent of the results for gapless chains and should be valid for any
massive one-dimensional model close to a conformal critical point.
