Abstract

Joint density of states (JDoS), which depends both on energy and another variable like order parameter providesmore information than the conventional density of states (DoS) which depend only on energy. Calculation of JDoS requires huge computational time. In this paper we employ two level method to calculate JDoS which requires relatively much less computational time. We demonstrate this method on a two dimensional Ising spin system,lattice spin model of double strand DNA (dsDNA) and Heisenberg ferromagnet.
