Topology in 2D CP**(N-1) models on the lattice: a critical comparison of different cooling techniques
B. Alles, L. Cosmai, M. D'Elia +1
Two-dimensional CP**(N-1) models are used to compare the behavior of different cooling techniques on the lattice. Cooling is one of the most frequently used tools to study on the l…
Topology in CP(N-1) models: a critical comparison of different cooling techniques
B. Alles, L. Cosmai, M. D'Elia +1
Various cooling methods, including a recently introduced one which smoothes out only quantum fluctuations larger than a given threshold, are applied to the study of topology in 2d…
Fixed point actions and on-shell tree-level Symanzik improvement
A. Papa
In this paper it is argued that the properties of the fixed point action of a renormalization group transformation can be used to implement the on-shell tree-level Symanzik improve…
Instanton classical solutions of SU(3) fixed point actions on open lattices
F. Farchioni, A. Papa
We construct instanton-like classical solutions of the fixed point action of a suitable renormalization group transformation for the SU(3) lattice gauge theory. The problem of the…
SU(3) surface tension from the lattice with the fixed point action
A. Papa
The surface tension at the deconfinement transition of SU(3) is determined with a parametrized version of the fixed point action of a renormalization group transformation on lattic…
SU(3) Thermodynamics on Small Lattices
A. Papa
The free energy density of the SU(3) gauge theory at temperatures T/T_c = 4/3, 3/2 and 2 is calculated on lattices with temporal extent as small as N_t = 2, 3 and spatial extent N_…
