Retrieving the optical potential from a Lattice simulation

We propose a method for the direct extraction of the complex 
hadron-hadron optical potential
(or, equivalently, the phase shift and inelasticity in a given channel) 
on the lattice, which does not require
the use of the multi-channel Luscher formalism, but the knowledge of a 
tower of energy levels only.
The approach works for any multi-particle states and tested explicitly 
on a set of synthetic data for the
pi eta/Kbar K system. Further, we show how a sufficiently large number 
of energy eigenvalues can be
obtained utilizing partial twisting.
