Dynamical fermion algorithm for variable actions

A new version of the two-step multi-boson algorithm is developed with different fermion actions in the multi-boson and noisy Metropolis steps.Comment: 8 pages, 2 figures, more discussion and references include

Embedding the N=2 Supersymmetric Yang-Mills Theory in the Adjoint Higgs-Yukawa Model on the Lattice

The N=2 supersymmetric Yang-Mills theory is formulated on the lattice. The feasibility of numerical simulations is discussed.Comment: 11 pages with 1 figure, CERN-TH.7479/9

Multi-bosonic algorithms for dynamical fermion simulations

Multi-bosonic fermion simulation algorithms are reviewed, with particular emphasis on a recent application in SU(2) Yang-Mills theory with light gluinos.Comment: latex, 14 pages; talk given at the workshop "Molecular Dynamics on Parallel Computers", February 1999, NIC, J\"ulic

Electroweak Phase Transition and Numerical Simulations in the SU(2) Higgs Model

Recent progress in non-perturbative investigations of the electroweak phase transition is reviewed, with special emphasis on numerical simulations in the four-dimen\-sional SU(2) Higgs model.Comment: 11 pages, latex, 2 figures. Lecture given at the $3^e$ Colloque Cosmologie, Paris, June 199
