Taming the dynamical sign problem in real-time evolution of quantum many-body problems
Guy Cohen, Emanuel Gull, David. R. Reichman +1
Current nonequilibrium Monte Carlo methods suffer from a dynamical sign problem that makes simulating real-time dynamics for long times exponentially hard. We propose a new `Inchwo…
Thermodynamics of the Hubbard model on stacked honeycomb and square lattices
Jakub Imriška, Emanuel Gull, Matthias Troyer
We present a numerical study of the Hubbard model on simply stacked honeycomb and square lattices, motivated by a recent experimental realization of such models with ultracold atom…
Voltage quench dynamics of a Kondo system
Andrey E. Antipov, Qiaoyuan Dong, Emanuel Gull
We examine the dynamics of a correlated quantum dot in the mixed valence regime. We perform numerically exact calculations of the current after a quantum quench from equilibrium by…
opendf - an implementation of the dual fermion method for strongly correlated systems
Andrey E. Antipov, James P. F. LeBlanc, Emanuel Gull
The dual fermion method is a multiscale approach for solving lattice problems of interacting strongly correlated systems. In this paper, we present the \texttt{opendf} code, an ope…
Superconducting Fluctuations in the Normal State of the Two-Dimensional Hubbard Model
Xi Chen, J. P. F. LeBlanc, Emanuel Gull
We compute the two-particle quantities relevant for superconducting correlations in the two-dimensional Hubbard model within the dynamical cluster approximation. In the normal stat…
Mechanisms of finite temperature magnetism in the three-dimensional Hubbard model
Daniel Hirschmeier, Hartmut Hafermann, Emanuel Gull +2
We examine the nature of the transition to the antiferromagnetically ordered state in the half-filled three-dimensional Hubbard model using the dual-fermion multiscale approach. Co…
