On the rotator Hamiltonian for the SUSU sigma-model in the delta-regime
J. Balog, F. Niedermayer, P. Weisz
We investigate some properties of the standard rotator approximation of the SUSU sigma-model in the delta-regime. In particular we show that the isospin susceptib…
Finite volume mass gap and free energy of the SU(N)xSU(N) chiral sigma model
Ferenc Niedermayer, Peter Weisz
We compute the free energy in the presence of a chemical potential coupled to a conserved charge in the effective SU(N)xSU(N) scalar field theory to third order for asymmetric volu…
Casimir squared correction to the standard rotator Hamiltonian for the O() sigma-model in the delta-regime
Ferenc Niedermayer, Peter Weisz
In a previous paper we found that the isospin susceptibility of the O() sigma-model calculated in the standard rotator approximation differs from the next-to-next to leading ord…
Flow equation for the scalar model in the large expansion and its applications
Sinya Aoki, Janos Balog, Tetsuya Onogi +1
We study the flow equation of the O() model in dimensions at the next-to-leading order (NLO) in the expansion. Using the Schwinger-Dyson equation, we derive 2-pt…
Flow equation for the large scalar model and induced geometries
Sinya Aoki, Janos Balog, Tetsuya Onogi +1
We study the proposal that a dimensional induced metric is constructed from a dimensional field theory using gradient flow. Applying the idea to the O() model an…
Perturbative analysis of the gradient flow in non-abelian gauge theories
Martin Lüscher, Peter Weisz
The gradient flow in non-abelian gauge theories on R^4 is defined by a local diffusion equation that evolves the gauge field as a function of the flow time in a gauge-covariant man…
