Charge ordering and correlation effects in the extended Hubbard model
Hanna Terletska, Tianran Chen, Emanuel Gull
We study the half filled extended Hubbard model on a two-dimensional square lattice using cluster dynamical mean field theory on clusters of size 8-20. We show that the model exhib…
Updated Core Libraries of the ALPS Project
A. Gaenko, A. E. Antipov, G. Carcassi +16
The open source ALPS (Algorithms and Libraries for Physics Simulations) project provides a collection of physics libraries and applications, with a focus on simulations of lattice…
Enhancement of hopping conductivity by spontaneous fractal ordering of low-energy sites
Tianran Chen, Brian Skinner
Variable-range hopping conductivity has long been understood in terms of a canonical prescription for relating the single-particle density of states to the temperature-dependent co…
Fixed Points of Belief Propagation -- An Analysis via Polynomial Homotopy Continuation
Christian Knoll, Franz Pernkopf, Dhagash Mehta +1
Belief propagation (BP) is an iterative method to perform approximate inference on arbitrary graphical models. Whether BP converges and if the solution is a unique fixed point depe…
Three Formulations of the Kuramoto Model as a System of Polynomial Equations
Tianran Chen, Jakub Marecek, Dhagash Mehta +1
We compare three formulations of stationary equations of the Kuramoto model as systems of polynomial equations. In the comparison, we present bounds on the numbers of real equilibr…
