Glueball wavefunctions
Philippe de Forcrand, Keh-Fei Liu
We measure Coulomb-gauge wavefunctions of the scalar and tensor glueballs in SU(2) Yang-Mills. The problem of contamination by flux states is discussed, and a new analysis method d…
The fermion sign problem: A new decoupling transformation, and a new simulation algorithm
Ghassan George Batrouni, Philippe de Forcrand
We discuss the Fermion sign problem and, by examining a very general Hubbard-Stratonovich (HS) transformation, argue that the sign problem cannot be solved with such methods. We pr…
Nonperturbative evaluation of the diffusion rate in field theory at high temperatures
Alexander Bochkarev, Philippe de Forcrand
Kramer's approach to the rate of the thermally activated escape from a metastable state is extended to field theory. Diffusion rate in the 1+1-dimensional Sine-Gordon model as a fu…
