99 9 Broad Histogram Method for Multiparametric Hamiltonians
We extended the Broad Histogram Method in order to obtain spectral degeneracies for systems with multiparametric Hamiltonians. As examples we obtained the critical lines for the square lattice Ising model with nearest and next-nearest neighbor interactions and the antiferromagnetic Ising model in an external field. For each system, the entire critical line is obtained using data from a single c...
متن کاملComment on “ A Comparison Between Broad Histogram and Multicanonical Methods ”
, seems to contain at least two mistakes which deserve comment, one concerning the numerical data, the other being of a conceptual kind. The numerical data of the entropy, presented in Fig. 1 of the above mentioned paper, do not only show statistical errors but also systematic deviations from the exact result. These systematic deviations are apparent in the (physically relevant) gradient of the...

متن کاملA comparison between broad histogram and multicanonical methods
We discuss the conceptual differences between the Broad Histogram (BHM) and reweighting methods in general, and particularly the so-called Multicanonical (MUCA) approaches. The main difference is that BHM is based on microcanonical, fixed-energy averages which depends only on the good statistics taken inside each energy level. The detailed distribution of visits among different energy levels, d...
متن کامل2 2 O ct 1 99 8 Extending the Broad Histogram Method for Continuous Systems ∗
We propose a way of extending the Broad Histogram Monte Carlo method (BHMC) to systems with continuous degrees of freedom, and we apply these ideas to investigate the three-dimensional XY-model. Our method gives results in excellent agreement with Metropolis and Histogram Monte Carlo simulations and calculates for the whole temperature range 1.2 < T < 4.7 using only 2 times more computer effort...
