Getting even with CLE
Gert Aarts, Kirill Boguslavski, Manuel Scherzer +3
In the landscape of approaches toward the simulation of Lattice Models with complex action the Complex Langevin (CL) appears as a straightforward method with a simple, well defined…
Beyond Complex Langevin Equations: positive representation of a class of complex measures
Erhard Seiler, Jacek Wosiek
A positive representation for a set of complex densities is constructed. In particular, complex measures on a direct product of U(1) groups are studied. After identifying general c…
Status of Complex Langevin
Erhard Seiler
I review the status of the Complex Langevin method, which was invented to make simulations of models with complex action feasible. I discuss the mathematical justification of the p…
Isospin susceptibility in the O() sigma-model in the delta-regime
Ferenc Niedermayer, Peter Weisz
We compute the isospin susceptibility in an effective O() scalar field theory (in dimensions), to third order in chiral perturbation theory (PT) in the delta--regime us…
Positive Representations of a Class of Complex Measures
Erhard Seiler, Jacek Wosiek
We study the problem of constructing positive representations of complex measures. In this paper we consider complex densities on a direct product of groups and look for rep…
Complex Langevin dynamics and zeroes of the fermion determinant
Gert Aarts, Erhard Seiler, Denes Sexty +1
QCD at nonzero baryon chemical potential suffers from the sign problem, due to the complex quark determinant. Complex Langevin dynamics can provide a solution, provided certain con…
