Numerical simulation of the Kardar-Parisi-Zhang equation
Matteo Beccaria, Giuseppe Curci
We simulate the Kardar-Parisi-Zhang equation in 2+1 dimensions. The Hopf-Cole transformation is used in order to obtain a stable numerical scheme. The two relevant critical exponen…

The Kramers equation simulation algorithm II. An application to the Gross-Neveu model
Matteo Beccaria, Giuseppe Curci, Luca Galli
We continue the investigation on the applications of the Kramers equation to the numerical simulation of field theoretic models. In a previous paper we have described the theory an…

The Kramers equation simulation algorithm I. Operator analysis
Matteo Beccaria, Giuseppe Curci
Using an operatorial formalism, we study the Kramers equation and its applications to numerical simulations. We obtain classes of algorithms which may be made precise at every desi…
