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…
In the search for the low-complexity sequences in prokaryotic and eukaryotic genomes: how to derive a coherent picture from global and local entropy measures
Claudia Acquisti, Paolo Allegrini, Patrizia Bogani +6
We investigate on a possible way to connect the presence of Low-Complexity Sequences (LCS) in DNA genomes and the nonstationary properties of base correlations. Under the hypothesi…
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…
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…
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 equation of state of randomly dilute Ising systems
P. Calabrese, M. De Prato, A. Pelissetto +1
We determine the critical equation of state of three-dimensional randomly dilute Ising systems, i.e. of the random-exchange Ising universality class. We first consider the small-ma…
Crossover from random-exchange to random-field critical behavior in Ising models
Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari
We compute the crossover exponent describing the crossover from the random-exchange to the random-field critical behavior in Ising systems. For this purpose, we consider the fi…
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…
Transmittivity of a Bose-Einstein condensate on a lattice: interference from period doubling and the effect of disorder
P. Vignolo, Z. Akdeniz, M. P. Tosi
We evaluate the particle current flowing in steady state through a Bose-Einstein condensate subject to a constant force in a quasi-onedimensional lattice and to attractive interact…
Collective dynamics of fermion clouds in cigar-shaped traps
Z. Akdeniz, P. Vignolo, M. P. Tosi
The propagation of zero sound in a spin-polarized Fermi gas under harmonic confinement is studied as a function of the mean-field interactions with a second Fermi gas. A local-dens…
Dynamic structure factor of the Ising model with purely relaxational dynamics
P. Calabrese, V. Martin-Mayor, A. Pelissetto +1
We compute the dynamic structure factor for the Ising model with a purely relaxational dynamics (model A). We perform a perturbative calculation in the expansion, at two loops…
