A Tensor Train Continuous Time Solver for Quantum Impurity Models
A. Erpenbeck, W. -T. Lin, T. Blommel +8
The simulation of strongly correlated quantum impurity models is a significant challenge in modern condensed matter physics that has multiple important applications. Thus far, the…
Ensemble Optimization Techniques for the Simulation of Slowly Equilibrating Systems
S. Trebst, D. A. Huse, E. Gull +3
Competing phases or interactions in complex many-particle systems can result in free energy barriers that strongly suppress thermal equilibration. Here we discuss how extended ense…
Role of three-particle vertex within dual fermion calculations
T. Ribic, P. Gunacker, S. Iskakov +5
We investigate the influence of self-energy diagrams beyond the two-particle vertex level within dual fermion theory. Specifically, we calculate the local three-particle vertex and…
The ALPS project release 1.3: open source software for strongly correlated systems
A. F. Albuquerque, F. Alet, P. Corboz +25
We present release 1.3 of the ALPS (Algorithms and Libraries for Physics Simulations) project, an international open source software project to develop libraries and application pr…
Diagrammatic Monte Carlo for Correlated Fermions
E. Kozik, K. Van Houcke, E. Gull +4
We show that Monte Carlo sampling of the Feynman diagrammatic series (DiagMC) can be used for tackling hard fermionic quantum many-body problems in the thermodynamic limit by prese…
Magnetic susceptibility of Ce: an LDA+DMFT study
S. V. Streltsov, E. Gull, A. O. Shorikov +3
The magnetic properties of Ce in the and phase are calculated within the LDA+DMFT approach. The magnetic susceptibility in these two phases shows a similar behavior over…
Symmetry projection schemes for Gaussian Monte Carlo methods
F. F. Assaad, P. Werner, P. Corboz +2
A novel sign-free Monte Carlo method for the Hubbard model has recently been proposed by Corney and Drummond. High precision measurements on small clusters show that ground state c…
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…
Shaping electronic flows with strongly correlated physics
A. Erpenbeck, E. Gull, G. Cohen
Nonequilibrium quantum transport is of central importance in nanotechnology. Its description requires the understanding of strong electronic correlations, which couple atomic-scale…
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…
Thermodynamics of the 3D Hubbard model on approach to the Neel transition
S. Fuchs, E. Gull, L. Pollet +4
We study the thermodynamic properties of the 3D Hubbard model for temperatures down to the Neel temperature using cluster dynamical mean-field theory. In particular we calculate th…
Fluctuation diagnostics of the electron self-energy: Origin of the pseudogap physics
O. Gunnarsson, T. Schäfer, J. P. F. LeBlanc +5
We demonstrate how to identify which physical processes dominate the low-energy spectral functions of correlated electron systems. We obtain an unambiguous classification through a…
