The normal-to-planar superfluid transition in Helium 3
Martino De Prato, Andrea Pelissetto, Ettore Vicari
We study the nature of the Helium-3 superfluid transition from the normal to the planar phase, which is expected to be stabilized by the dipolar interactions. We determine the RG f…
Spin models with random anisotropy and reflection symmetry
Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari
We study the critical behavior of a general class of cubic-symmetric spin systems in which disorder preserves the reflection symmetry , for . Th…
Confining strings in representations with common -ality
Luigi Del Debbio, Haralambos Panagopoulos, Ettore Vicari
We study the spectrum of confining strings in SU(3) pure gauge theory, by means of lattice Monte Carlo simulations, using torelon operators in different representations of the gaug…
The three-dimensional randomly dilute Ising model: Monte Carlo results
P. Calabrese, V. Martin-Mayor, A. Pelissetto +1
We perform a high-statistics simulation of the three-dimensional randomly dilute Ising model on cubic lattices with . We choose a particular value of the density, x…
On the nature of the finite-temperature transition in QCD
Agostino Butti, Andrea Pelissetto, Ettore Vicari
We discuss the nature of the finite-temperature transition in QCD with N_f massless flavors. Universality arguments show that a continuous (second-order) transition must be related…
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…
