Electronic instabilities in Penrose quasi-crystals: competition, coexistence and collaboration of order
Jonas B. Profe, Carsten Honerkamp, Sebastian Achilles +1
Quasicrystals lack translational symmetry, but can still exhibit long-ranged order, promoting them to candidates for unconventional physics beyond the paradigm of crystals. Here, w…
Leveraging Machine Learning to Alleviate Hubbard Model Sign Problems
Jan-Lukas Wynen, Evan Berkowitz, Stefan Krieg +2
Lattice Monte Carlo calculations of interacting systems on non-bipartite lattices exhibit an oscillatory imaginary phase known as the phase or sign problem, even at zero chemical p…
Tracking the Footprints of Spin Fluctuations: A MultiMethod, MultiMessenger Study of the Two-Dimensional Hubbard Model
Thomas Schäfer, Nils Wentzell, Fedor Šimkovic +23
The Hubbard model represents the fundamental model for interacting quantum systems and electronic correlations. Using the two-dimensional half-filled Hubbard model at weak coupling…
The Semimetal-Mott Insulator Quantum Phase Transition of the Hubbard Model on the Honeycomb Lattice
Johann Ostmeyer, Evan Berkowitz, Stefan Krieg +3
We take advantage of recent improvements in the grand canonical Hybrid Monte Carlo algorithm, to perform a precision study of the single-particle gap in the hexagonal Hubbard model…
Pseudogap opening in the two-dimensional Hubbard model: A functional renormalization group analysis
Cornelia Hille, Daniel Rohe, Carsten Honerkamp +1
Using the recently introduced multiloop extension of the functional renormalization group, we compute the frequency- and momentum-dependent self-energy of the two-dimensional Hubba…
Accelerating Hybrid Monte Carlo simulations of the Hubbard model on the hexagonal lattice
Stefan Krieg, Thomas Luu, Johann Ostmeyer +2
We present different methods to increase the performance of Hybrid Monte Carlo simulations of the Hubbard model in two-dimensions. Our simulations concentrate on a hexagonal lattic…
Real-Time Dynamics of Typical and Untypical States in Non-Integrable Systems
Jonas Richter, Fengping Jin, Hans De Raedt +3
For a class of typical states, the real-time and real-space dynamics of non-equilibrium density profiles has been recently studied for integrable models, i.e. the spin-1/2 XXZ chai…
Charge diffusion in the one-dimensional Hubbard model
R. Steinigeweg, F. Jin, H. De Raedt +2
We study the real-time and real-space dynamics of charge in the one-dimensional Hubbard model in the limit of high temperatures. To this end, we prepare pure initial states with sh…
High-performance functional renormalization group calculations for interacting fermions
J. Lichtenstein, D. Sánchez de la Peña, D. Rohe +3
We derive a novel computational scheme for functional Renormalization Group (fRG) calculations for interacting fermions on 2D lattices. The scheme is based on the exchange parametr…
Finite-temperature charge transport in the one-dimensional Hubbard model
F. Jin, R. Steinigeweg, F. Heidrich-Meisner +2
We study the charge conductivity of the one-dimensional repulsive Hubbard model at finite temperature using the method of dynamical quantum typicality, focusing at half filling. Th…
