Lattice field theory is one of the most important methods to access non-perturbative property of quantum field theory. SU(2)+Higgs model, which describes several important phenomena of particle physics and condensed matter physics, has been investigated using Monte-Carlo simulation for many years. In this talk, we discuss phase structure of SU(2)+multiple Higgs model. Especially we show exploratory results for zero-temperature phase structure.

Keywords: Lattice field theory, two Higgs doublet models, superconductivity
