Mass gap in the 2D O(3) non-linear sigma model with a theta=pi term
B. Alles, A. Papa
By analytic continuation to real theta of data obtained from numerical simulation at imaginary theta we study the Haldane conjecture and show that the O(3) non-linear sigma model w…
Entanglement and correlation functions following a local quench: a conformal field theory approach
Pasquale Calabrese, John Cardy
We show that the dynamics resulting from preparing a one-dimensional quantum system in the ground state of two decoupled parts, then joined together and left to evolve unitarily wi…
Quantum Quenches in Extended Systems
Pasquale Calabrese, John Cardy
We study in general the time-evolution of correlation functions in a extended quantum system after the quench of a parameter in the hamiltonian. We show that correlation functions…
Correlation functions of one-dimensional anyonic fluids
Pasquale Calabrese, Mihail Mintchev
A universal description of correlation functions of one-dimensional anyonic gapless systems in the low-momentum regime is presented. We point out a number of interesting features,…
Renormalised four-point coupling constant in the three-dimensional O(N) model with N=0
Andrea Pelissetto, Ettore Vicari
We simulate self-avoiding walks on a cubic lattice and determine the second virial coefficient for walks of different lengths. This allows us to determine the critical value of the…
Multicritical behavior of two-dimensional anisotropic antiferromagnets in a magnetic field
Andrea Pelissetto, Ettore Vicari
We study the phase diagram and multicritical behavior of anisotropic Heisenberg antiferromagnets on a square lattice in the presence of a magnetic field along the easy axis. We arg…
Evidence for a floating phase of the transverse ANNNI model at high frustration
Matteo Beccaria, Massimo Campostrini, Alessandra Feo
We study the transverse quantum ANNNI model in the region of high frustration (k>0.5) using the DMRG algorithm. We obtain a precise determination of the phase diagram, showing clea…
