We derive a formula that expresses the density of states of a system with continuous degrees of freedom as a function of microcanonical averages of squared gradient and Laplacian of the Hamiltonian. This result is then used to propose a novel flat-hi

We present a fast, hierarchical, and adaptive algorithm for Metropolis Monte Carlo simulations of systems with long-range interactions that reproduces the dynamics of a standard implementation exactly, i.e., the generated configurations and consequen

We show how polymer models with untruncated intra-molecular interactions and continuous degrees of freedom can be investigated by means of Monte Carlo techniques even for large systems. To this end we adapt Clisby’s method for the simulation of sel

We show how the well-known Wang-Landau method can be modified to produce non-flat distributions. Through the choice of a suitable profile this can lead to an increase in efficiency for some systems. Examples for such an enhancement are provided.

Abstract We describe how metastable states of Ising spin glasses can be counted by means of Monte Carlo computer simulations. The method is applied to systems defined on hypercubic lattices in one to six dimensions with up to about 103 spins. It is s

The complex behavior of systems like spin glasses, proteins or neural networks is typically explained in terms of a rugged energy or fitness landscape. Within the high-dimensional conformation space of these systems one finds features like barriers,

We show how a Monte Carlo method for generating self-avoiding walks on lattice geometries which employs a binary-tree data-structure can be adapted for hard-sphere polymers with continuous degrees of freedom. Data suggests that the time per Monte Car
