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…
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…
On the generalised eigenvalue method and its relation to Prony and generalised pencil of function methods
Matthias Fischer, Bartosz Kostrzewa, Johann Ostmeyer +3
We discuss the relation of three methods to determine energy levels in lattice QCD simulations: the generalised eigenvalue, the Prony and the generalised pencil of function methods…
Physics of Beer Tapping -- Lower vs. Upper Bottle
Johann Ostmeyer
"Beer tapping" is a well known prank where a bottle of carbonised liquid strikes another bottle of carbonised liquid from above, with the usual result that the lower bottle foams o…
