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…

Implications of spin symmetry for XYZ states

Q. Wang, V. Baru, E. Epelbaum +4

Numerous exotic candidates containing a heavy quark and anti-quark (the so-called states) have been reported since the observation of the in 2003. For these systems…

Avoiding Ergodicity Problems in Lattice Discretizations of the Hubbard Model

Jan-Lukas Wynen, Evan Berkowitz, Christopher Körber +2

The Hubbard model arises naturally when electron-electron interactions are added to the tight-binding descriptions of many condensed matter systems. For instance, the two-dimension…

Three neutrons from Lattice QCD

Jan-Lukas Wynen, Evan Berkowitz, Thomas Luu +2

We present a study on ab-initio calculations of three-neutron correlators from Lattice QCD. We extend the method of baryon blocks to systems of three spacially displaced baryons. T…

The line shapes of the and in the elastic and inelastic channels revisited

Q. Wang, V. Baru, A. A. Filin +3

The most recent experimental data for all measured production and decay channels of the bottomonium-like states and are analysed simultaneously using solu…

A primer to numerical simulations: The perihelion motion of Mercury

Christopher Körber, Inka Hammer, Jan-Lukas Wynen +3

Numerical simulations are playing an increasingly important role in modern science. In this work it is suggested to use a numerical study of the famous perihelion motion of the pla…

Interplay of quark and meson degrees of freedom in near-threshold states: A practical parametrisation for line shapes

F. -K. Guo, C. Hanhart, Yu. S. Kalashnikova +5

We propose a practical parametrisation for the line shapes of near-threshold states compatible with all requirements of unitarity and analyticity. The coupled-channel system underl…
