General method to perform Microcanonical Monte Carlo Simulations
G. Palma, A. Riveros
Monte Carlo simulations have boosted the numerical study of several different physical systems and in particular, the canonical ensemble has been especially useful because of the e…
Finite-size corrections to scaling of the magnetization distribution in the -model at zero temperature
G. Palma, F. Niedermayer, Z. Rácz +2
The zero-temperature, classical -model on an square-lattice is studied by exploring the distribution of its centered and normalized magnetization in t…
Meron-cluster simulation of the quantum antiferromagnetic Heisenberg model in a magnetic field in one- and two-dimensions
G. Palma, A. Riveros
Motivated by the numerical simulation of systems which display quantum phase transitions, we present a novel application of the meron-cluster algorithm to simulate the quantum anti…
Cluster Algorithm Renormalization Group Study of Universal Fluctuations in the 2D Ising Model
G. Palma, D. Zambrano
In this paper we propose a novel method to study critical systems numerically by a combined collective-mode algorithm and Renormalization Group on the lattice. This method is an im…
Comment on "Temperature dependent fluctuations in the two-dimensional XY model"
G. Palma
We comment the recent published article entitled "Temperature dependent fluctuations in the two-dimensional XY model", appeared in J. Phys. A: Math.Gen. 38 (2005) 5603.
Finite size scaling in the 2D XY-model and generalized universality
G. Palma, T. Meyer, R. Labbé
In recent works (BHP), a generalized universality has been proposed, linking phenomena as dissimilar as 2D magnetism and turbulence. To test these ideas, we performed a MC study of…
