   Dynamics of the Scalar Condensate in thermal 4D self-interacting Scalar Field Theory on the Lattice

   P. Cea🇮🇹 · M. Consoli🇮🇹 · L. Cosmai🇮🇹

   We simulate a four dimensional self-interacting scalar field theory on the lattice at finite temperature. By varying temperature, the system undergoes a phase transition from broken phase to symmetric phase. Our data show that the zero-momentum field renormalization increases by approaching critical temperature. On the other hand, finite-momentum wave-function renormalization remains remarkably constant.

   A new fermion Hamiltonian for lattice gauge theory

   Michael Creutz (Brookhaven)🇺🇸 · Ivan Horváth (Kentucky)🇺🇸 · Herbert Neuberger (Rutgers)🇺🇸

   We formulate Hamiltonian vector-like lattice gauge theory using the overlap formula for the spatial fermionic part, $H_f$. We define a chiral charge, $Q_5$ which commutes with $H_f$, but not with the electric field term. There is an interesting relation between the chiral charge and the fermion energy with consequences for chiral anomalies.
