Improved lattice operators: the case of the topological charge density
C. Christou, A. Di Giacomo, H. Panagopoulos +1
We analyze the properties of a class of improved lattice topological charge density operators, constructed by a smearing-like procedure. By optimizing the choice of the parameters…
Improving the topological charge density operator on the lattice
C. Christou, A. Di Giacomo, H. Panagopoulos +1
We analyze the properties of a class of improved lattice topological charge density operators, constructed by a smearing-like procedure. By optimizing the choice of the parameters…
Topological charge density renormalization in the presence of dynamical fermions
B. Alles, A. Di Giacomo, H. Panagopoulos +1
We study the renormalization group behaviour of the topological charge density in full QCD on the lattice. We propose a way of extracting the necessary renormalization functions fr…
Fractal Behaviour in the O(3) Model
C. Christou, F. K. Diakonos, H. Panagopoulos
We study domain formation in the two-dimensional O(3) model near criticality. The fractal dimension of these domains is determined with good statistical accuracy.
