Description

The Hamiltonian formulation of Lattice QCD with staggered fermions
in the strong coupling limit has no sign problem at non-zero baryon density
and allows for Quantum Monte Carlo simulations.

We have extended this formalism to two flavors,
and after a resummation, there is no sign problem
both for non-zero baryon and isospin chemical potential.
We report on recent progress on the implementation
of the Quantum Monte Carlo simulations and present results
on the baryon and isospin densities in the chiral limit.
These will be compared with Meanfield theory.
