Five-loop epsilon expansion for O(n)xO(m) spin models
Pasquale Calabrese, Pietro Parruccini
We compute the Renormalization Group functions of a Landau-Ginzburg-Wilson Hamiltonian with O(n)x O(m) symmetry up to five-loop in Minimal Subtraction scheme. The line n^+(m,d), wh…
Crossover behavior in three-dimensional dilute spin systems
Pasquale Calabrese, Pietro Parruccini, Andrea Pelissetto +1
We study the crossover behaviors that can be observed in the high-temperature phase of three-dimensional dilute spin systems, using a field-theoretical approach. In particular, for…
Critical behavior of frustrated spin systems with nonplanar orderings
Pietro Parruccini
The critical behavior of frustrated spin systems with nonplanar orderings is analyzed by a six-loop study in fixed dimension of an effective OO Landau-Ginzburg-Wi…
Critical thermodynamics of three-dimensional chiral model for N > 3
P. Calabrese, P. Parruccini, A. I. Sokolov
The critical behavior of the three-dimensional -vector chiral model is studied for arbitrary . The known six-loop renormalization-group (RG) expansions are resummed using the…
