Calculation of CP Violation in Non-leptonic Kaon Decay on the Lattice
We give a progress report of our lattice calculation of direct and indirect
CP violation in kaon decays, parametrized as and ,
which require non-perturbative calculation of the matrix elements of the
Standard Model effective Hamiltonian.Comment: Talk presented at CIPANP2003, New York City, May 19-24, 2003, 4

Two-dimensional Lattice Gross-Neveu Model with Wilson Fermion Action at Finite Temperature and Chemical Potential
We investigate the phase structure of the two-dimensional lattice Gross-Neveu
model formulated with the Wilson fermion action to leading order of 1/N
expansion. Structural change of the parity-broken phase under the influence of
finite temperature and chemical potential is studied. The connection between
the lattice phase structure and the chiral phase transition of the continuum
theory is clarified.Comment: 42 pages, 20 EPS figures, using REVTe
