Query: Emptiness formation probability of the XXZ spin-1/2 Heisenberg chain at
  Delta=1/2   Using a multiple integral representation for the correlation functions, we
compute the emptiness formation probability of the XXZ spin-1/2 Heisenberg
chain at anisotropy Delta=1/2. We prove it is expressed in term of the number
of alternating sign matrices.
