The Complex Langevin method: When can it be trusted?

Gert Aarts, Erhard Seiler, Ion-Olimpiu Stamatescu

We analyze to what extent the complex Langevin method, which is in principle capable of solving the so-called sign problems, can be considered as reliable. We give a formal derivat…

Adaptive stepsize and instabilities in complex Langevin dynamics

Gert Aarts, Frank A. James, Erhard Seiler +1

Stochastic quantization offers the opportunity to simulate field theories with a complex action. In some theories unstable trajectories are prevalent when a constant stepsize is em…

The repulsive core of the NN potential and the operator product expansion

Sinya Aoki, Janos Balog, Peter Weisz

We investigate the short distance behavior of the nucleon--nucleon (NN) potential defined through the Bethe-Salpeter wave function, by perturbatively calculating anomalous dimensio…

The puzzle of apparent linear lattice artifacts in the 2d non-linear sigma-model and Symanzik's solution

Janos Balog, Ferenc Niedermayer, Peter Weisz

Lattice artifacts in the 2d O(n) non-linear sigma-model are expected to be of the form O(a^2), and hence it was (when first observed) disturbing that some quantities in the O(3) mo…

Logarithmic corrections to O(a^2) lattice artifacts

Janos Balog, Ferenc Niedermayer, Peter Weisz

We compute logarithmic corrections to the O(a^2) lattice artifacts for a class of lattice actions for the non-linear O(n) sigma-model in two dimensions. The generic leading artifac…
