✦ Synopsis

We investigate a first-order phase transition from a non-magnetic phase to a non-frustrated phase of a two-dimensional triangular lattice with antiferromagnetic bonds. A cellular automaton is defined, which chooses a magnetic state of subsequent lattice sites, where an interphase boundary arrives, as to minimise the local energy. The ground state magnetic state is found to be unstable with respect to the point defects of magnetic structure.

The interplay between antiferromagnetism (AF) and superconductivity (SC) in cuprates is studied for the two-dimensional Hubbard model with a diagonal transfer t 0 , using a variational Monte Carlo method. Optimizing an improved function for strongly correlated values of U/t, we construct phase diagr
