In this work we introduce the dual boson diagrammatic Monte Carlo technique for strongly interacting electronic systems. This method combines the strength of dynamical mean-filed theory for nonperturbative description of local correlations with the s

Publikováno v: Computer Physics Communications. 213:235-251
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 models and strongly correlated systems. The libraries provide a conven

Repairing the surface of InAs-based topological heterostructures
Autor: Michael J. Manfra, A. Jouan, T. Wang, S. J. Pauka, B. Harlech-Jones, David J. Reilly, Jan Gukelberger, C. N. Allen, John King Gamble, J. D. S. Witt, Sergei Gronin, Geoffrey C. Gardner, Maja C. Cassidy, Candice Thomas
Publikováno v: Journal of Applied Physics. 128:114301
Candidate systems for topologically-protected qubits include two-dimensional electron gases (2DEGs) based on heterostructures exhibiting a strong spin–orbit interaction and superconductivity via the proximity effect. For InAs- or InSb-based materia

Diagrammatic Monte Carlo approach for diagrammatic extensions of dynamical mean-field theory: Convergence analysis of the dual fermion technique
Autor: Jan Gukelberger, Hartmut Hafermann, Evgeny Kozik
Publikováno v: Physical Review B. 96
The dual-fermion approach provides a formally exact prescription for calculating properties of a correlated electron system in terms of a diagrammatic expansion around dynamical mean-field theory (DMFT). Most practical implementations, however, negle

Ising antiferromagnet in the two-dimensional Hubbard model with mismatched Fermi surfaces
Autor: Jan Gukelberger, Lei Wang, Lode Pollet
Publikováno v: Physical Review B. 95
We study the phase diagram of the two-dimensional repulsive Hubbard model with spin-dependent anisotropic hopping at half filling. The system develops Ising antiferromagnetic long-range order already at infinitesimal repulsive interaction strength in

Fulde-Ferrell-Larkin-Ovchinnikov pairing as leading instability on the square lattice
Autor: Jan Gukelberger, Sebastian Lienert, Matthias Troyer, Evgeny Kozik, Lode Pollet
Publikováno v: Physical Review B. 94
We study attractively interacting spin-1/2 fermions on the square lattice subject to a spin population imbalance. Using unbiased diagrammatic Monte Carlo simulations we find an extended region in the parameter space where the Fermi liquid is unstable

p-Wave Superfluidity by Spin-Nematic Fermi Surface Deformation
Autor: Matthias Troyer, Evgeny Kozik, Jan Gukelberger, Manfred Sigrist, Lode Pollet, Boris Svistunov, Nikolay Prokof'ev
Publikováno v: Physical Review Letters
We study attractively interacting fermions on a square lattice with dispersion relations exhibiting strong spin-dependent anisotropy. The resulting Fermi surface mismatch suppresses the s-wave BCS-type instability, clearing the way for unconventional
