# Program package for multicanonical simulations of U(1) lattice gauge theory—Second version

## Description

Abstract A new version STMCMUCA_V1_1 of our program package is available. It eliminates compatibility problems of our Fortran 77 code, originally developed for the g77 compiler, with Fortran 90 and 95 compilers. Title of program: STMC_U1MUCA_v1_02 Catalogue Id: AEET_v1_1 Nature of problem Efficient Markov chain Monte Carlo simulation of U(1) lattice gauge theory (or other continuous systems) close to its phase transition. Measurements and analysis of the action per plaquette, the specific heat, Polyakov loops and their structure factors.
