Quantifying nonuniversal corner free-energy contributions in weakly-anisotropic two-dimensional critical systems
Florian Kischel, Stefan Wessel
We derive an exact formula for the corner free-energy contribution of weakly-anisotropic two-dimensional critical systems in the Ising universality class on rectangular domains, ex…
Sublattice-selective percolation on bipartite planar lattices
Jonas Wattendorff, Stefan Wessel
In conventional site percolation, all lattice sites are occupied with the same probability. For a bipartite lattice, sublattice-selective percolation instead involves two independe…
Thermodynamics of the spin-1/2 Heisenberg antiferromagnet on the star lattice
Adrien Reingruber, Nils Caci, Stefan Wessel +1
Using a combination of quantum Monte Carlo simulations in adapted cluster bases, the finite temperature Lanczos method, and an effective Hamiltonian approach, we explore the thermo…
Excitation Gap Scaling near Quantum Critical Three-Dimensional Antiferromagnets
Maximilian Lohöfer, Stefan Wessel
By means of large-scale quantum Monte Carlo simulations, we examine the quantum critical scaling of the magnetic excitation gap (the triplon gap) in a three-dimensional dimerized q…
Finite-size effects in Luther-Emery phases of Holstein and Hubbard models
J. Greitemann, S. Hesselmann, S. Wessel +2
The one-dimensional Holstein model and its generalizations have been studied extensively to understand the effects of electron-phonon interaction. The half-filled case is of partic…
Dynamical structure factors and excitation modes of the bilayer Heisenberg model
M. Lohöfer, T. Coletta, D. G. Joshi +4
Using quantum Monte Carlo simulations along with higher-order spin-wave theory, bond-operator and strong-coupling expansions, we analyse the dynamical spin structure factor of the…
Anomalous Behavior of Spin Systems with Dipolar Interactions
David Peter, Steffen Müller, Stefan Wessel +1
We study the properties of spin systems realized by cold polar molecules interacting via dipole-dipole interactions in two dimensions. Using a spin wave theory, that allows for the…
The ALPS project release 2.0: Open source software for strongly correlated systems
B. Bauer, L. D. Carr, H. G. Evertz +29
We present release 2.0 of the ALPS (Algorithms and Libraries for Physics Simulations) project, an open source software project to develop libraries and application programs for the…
