Strong coupling expansion for finite temperature Yang-Mills theory in the confined phase (2008)

Langelage, Jens, Münster, Gernot, Philipsen, Owe

We perform euclidean strong coupling expansions for Yang Mills theory on the lattice at finite temperature. After setting up the formalism for general SU(N), we compute the first few terms of the...

Interfacial roughening in field theory (2008)

Köpf, Michael H., Münster, Gernot

In the rough phase, the width of interfaces separating different phases of statistical systems increases logarithmically with the system size. This phenomenon is commonly described in terms of the...

The interfacial profile in two-loop order (2006)

Küster, Jens, Münster, Gernot

The profile of interfaces separating different phases of statistical systems is investigated in the framework of renormalized field theory. The profile function is calculated analytically in the...

Twisted mass lattice QCD with non-degenerate quark masses (2006)

Münster, Gernot, Sudmann, Tobias

Quantum Chromodynamics on a lattice with Wilson fermions and a chirally twisted mass term is considered in the framework of chiral perturbation theory. For two and three numbers of quark flavours,...

Dieses Lehrbuch für Studierende der Physik orientiert sich in der Stoffauswahl an den Inhalten einer zweisemestrigen Kursvorlesung über Quantentheorie. Die behandelten Themen wrden ausführlich und...

Chiral perturbation theory for twisted mass QCD (2004)

Münster, Gernot, Schmidt, Christian, Scholz, Enno E.

Quantum Chromodynamics on a lattice with Wilson fermions and a chirally twisted mass term for two degenerate quark flavours is considered in the framework of chiral perturbation theory. The pion...

On the phase structure of twisted mass lattice QCD (2004)

Münster, Gernot

The introduction of a chirally twisted mass term has been proposed as an attractive approach to O(a) improvement of Quantum Chromodynamics with Wilson fermions on a lattice. For numerical simulation...

Profile and width of rough interfaces (2004)

Müller, Melanie, Münster, Gernot

In the context of Landau theory and its field theoretical refinements, interfaces between coexisting phases are described by intrinsic profiles. These intrinsic interface profiles, however, are...

Chiral perturbation theory for partially quenched twisted mass lattice QCD (2004)

Münster, Gernot, Schmidt, Christian, Scholz, Enno E.

Partially quenched Quantum Chromodynamics with Wilson fermions on a lattice is considered in the framework of chiral perturbation theory. Two degenerate quark flavours are associated with a chirally...

Chiral perturbation theory for lattice QCD with a twisted mass term (2003)

Münster, Gernot, Schmidt, Christian

Quantum Chromodynamics on a lattice with Wilson fermions and a chirally twisted mass term for two degenerate quark flavours is considered in the framework of chiral perturbation theory. The pion mass...

Perturbation theory for the two-dimensional abelian Higgs model in the unitary gauge (2003)

Scholz, Enno E., Münster, Gernot

In the unitary gauge the unphysical degrees of freedom of spontaneously broken gauge theories are eliminated. The Feynman rules are simpler than in other gauges, but it is non-renormalizable by the...

The classical nucleation rate in two dimensions (2002)

Münster, Gernot, Rutkevich, Sergei B.

In many systems in condensed matter physics and quantum field theory, first order phase transitions are initiated by the nucleation of bubbles of the stable phase. In homogeneous nucleation theory...

Dynamical suppression of large instantons (2001)

Münster, Gernot, Kamp, Christel

We investigate the distribution of instanton sizes in the framework of a simplified model for ensembles of instantons. This model takes into account the non-diluteness of instantons. The infrared...

On the 1-loop lattice perturbation theory of the supersymmetric Ward identities (2000)

Farchioni, Federico, Feo, Alessandra, Galla, Tobias, Gebert, Claus, Kirchner, Robert, Montvay, István, ...

The one loop corrections to the supersymmetric Ward identities (WIs) in the discretized N=1 SU(2) supersymmetric Yang-Mills theory can be investigated by means of lattice perturbation theory. The...

Semiclassical calculation of the nucleation rate for first order phase transitions in the 2-dimensional phi^4-model beyond the thin wall approximation (2000)

Münster, Gernot, Rutkevich, Sergei B.

In many systems in condensed matter physics and quantum field theory, first order phase transitions are initiated by the nucleation of bubbles of the stable phase. Traditionally, this process is...

Distribution of instanton sizes in a simplified instanton gas model (2000)

Münster, Gernot, Kamp, Christel

We investigate the distribution of instanton sizes in the framework of a simplified model for ensembles of instantons. This model takes into account the non-diluteness of instantons. The infrared...

Numerical simulations of dynamical gluinos in SU(3) Yang-Mills theory: first results (1999)

Feo, Alessandra, Kirchner, Robert, Luckmann, Silke, Montvay, Istvan, Münster, Gernot

In a numerical Monte Carlo simulation of SU(3) Yang-Mills theory with dynamical gluinos we have investigated the behaviour of the expectation value of the scalar and pseudoscalar gluino condensates...

Analytical Calculation of the Nucleation Rate for First Order Phase Transitions beyond the Thin Wall Approximation (1999)

Münster, Gernot, Rotsch, Sabine

First order phase transitions in general proceed via nucleation of bubbles. A theoretical basis for the calculation of the nucleation rate is given by the homogeneous nucleation theory of Langer and...

Münster, Gernot

Some points concerning the relation of strings to interfaces in statistical systems are discussed.

The Interface Tension of the Three-dimensional Ising Model in Two-loop Order (1997)

Hoppe, Peter, Münster, Gernot

In liquid mixtures and other binary systems at low temperatures the pure phases may coexist, separated by an interface. The interface tension vanishes according to $\sigma = \sigma_0 (1 -...

Field Theory, Critical Phenomena and Interfaces (1996)

Münster, Gernot, Grießhammer, Harald, Lehmann, Dirk

These lecture notes want to illustrate the close connection between statistical mechanics and field theory not only on the formal level, i.e. that many concepts of one area can easily be taken over...
