The finite-temperature chiral transition in QCD with adjoint fermions
Francesco Basile, Andrea Pelissetto, Ettore Vicari
We study the nature of the finite-temperature chiral transition in QCD with N_f light quarks in the adjoint representation (aQCD). Renormalization-group arguments show that the tra…
Interacting N-vector order parameters with O(N) symmetry
Andrea Pelissetto, Ettore Vicari
We consider the critical behavior of the most general system of two N-vector order parameters that is O(N) invariant. We show that it may a have a multicritical transition with enl…
Two-Dimensional Heisenberg Model with Nonlinear Interactions: 1/N Corrections
Sergio Caracciolo, Bortolo Matteo Mognetti, Andrea Pelissetto
We investigate a two-dimensional classical W(\bsigma_i\cdot \bsigma_j)$ in the large-N limit, focusing on the finite-tem…
The scaling equation of state of the three-dimensional O(N) universality class: N >= 4
Agostino Butti, Francesco Parisen Toldin, Andrea Pelissetto +1
We determine the critical equation of state of the three-dimensional O(N) universality class, for N=4, 5, 6, 32, 64. The N=4 is relevant for the chiral phase transition in QCD with…
Multicritical behavior in frustrated spin systems with noncollinear order
Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari
We investigate the phase diagram and, in particular, the nature of the the multicritical point in three-dimensional frustrated -component spin models with noncollinear order in…
Correction-to-scaling exponents for two-dimensional self-avoiding walks
Sergio Caracciolo, Anthony J. Guttmann, Iwan Jensen +3
We study the correction-to-scaling exponents for the two-dimensional self-avoiding walk, using a combination of series-extrapolation and Monte Carlo methods. We enumerate all self-…
Critical behavior of O(2)xO(N) symmetric models
Pasquale Calabrese, Pietro Parruccini, Andrea Pelissetto +1
We investigate the controversial issue of the existence of universality classes describing critical phenomena in three-dimensional statistical systems characterized by a matrix ord…
