High-precision estimates of critical quantities by means of improved Hamiltonians
M. Campostrini, M. Hasenbusch, A. Pelissetto +2
Three-dimensional spin models of the Ising and XY universality classes are studied by a combination of high-temperature expansions and Monte Carlo simulations applied to improved H…
Critical exponents and equation of state of three-dimensional spin models
M. Campostrini, M. Hasenbusch, A. Pelissetto +2
Three-dimensional spin models of the Ising and XY universality classes are studied by a combination of high-temperature expansions and Monte Carlo simulations. Critical exponents a…
Critical behavior of the three-dimensional XY universality class
Massimo Campostrini, Martin Hasenbusch, Andrea Pelissetto +2
We improve the theoretical estimates of the critical exponents for the three-dimensional XY universality class. We find alpha=-0.0146(8), gamma=1.3177(5), nu=0.67155(27), eta=0.038…
Linked-Cluster Expansion of the Ising Model
Massimo Campostrini
The linked-cluster expansion technique for the high-temperature expansion of spin model is reviewed. A new algorithm for the computation of three-point and higher Green's functions…
The critical equation of state of three-dimensional XY systems
Massimo Campostrini, Andrea Pelissetto, Paolo Rossi +1
We address the problem of determining the critical equation of state of three-dimensional XY systems. For this purpose we first consider the small-field expansion of the effective…
