Tricritical Behavior of Two-Dimensional Scalar Field Theories
M. Asorey, J. G. Esteve, F. Falceto +1
We compute by Monte Carlo numerical simulations the critical exponents of two-dimensional scalar field theories at the tricritical point. The results are in agreement with t…

A Perturbative/Variational Approach to Quantum Lattice Hamiltonians
J. G. Esteve, Germán Sierra
We propose a method to construct the ground state of local lattice hamiltonians with the generic form , where is a coupling constant and is a hamiltoni…
