Critical limit and anisotropy in the two-point correlation function of three-dimensional O(N) models
Massimo Campostrini, Andrea Pelissetto, Paolo Rossi +1
In three-dimensional O(N) models, we investigate the low-momentum behavior of the two-point Green's function G(x) in the critical region of the symmetric phase. We consider physica…
The large-N expansion of unitary-matrix models
Paolo Rossi, Massimo Campostrini, Ettore Vicari
The general features of the 1/N expansion in statistical mechanics and quantum field theory are briefly reviewed both from the theoretical and from the phenomenological point of vi…
Critical behavior of the correlation function of three-dimensional O(N) models in the symmetric phase
Massimo Campostrini, Paolo Rossi, Andrea Pelissetto +1
We present new strong-coupling series for O(N) spin models in three dimensions, on the cubic and diamond lattices. We analyze these series to investigate the two-point Green's func…
A strong-coupling analysis of two-dimensional O(N) sigma models with N<=2 on square, triangular and honeycomb lattices
Massimo Campostrini, Andrea Pelissetto, Paolo Rossi +1
The critical behavior of two-dimensional models with on the square, triangular, and honeycomb lattices is investigated by an analysis of the strong-coupl…
A strong-coupling analysis of two-dimensional O(N) sigma models with on square, triangular and honeycomb lattices
Massimo Campostrini, Andrea Pelissetto, Paolo Rossi +1
Recently-generated long strong-coupling series for the two-point Green's functions of asymptotically free lattice models are analyzed, focusing on the evaluation o…
