The chiral critical point from the strong coupling expansion
Jangho Kim, Pratitee Pattanaik, Wolfgang Unger
The strong coupling expansion for staggered fermions allows for Monte Carlo simulations using a dual representation. It has a mild sign problem for low values of the inverse gauge…
Quantum sampling on a quantum annealer for large volumes in the strong coupling limit for gauge group U(3)
Jangho Kim, Thomas Luu, Wolfgang Unger
In our previous studies [1, 2], we confirmed that a quantum annealer can be used for importance sampling of gauge theories. In this paper, we extend the previous results to larger…
Chiral Transition via Strong Coupling Expansion
Jangho Kim, Pratitee Pattanaik, Wolfgang Unger
We investigate the chiral transition of lattice gauge theory based on the strong coupling expansion. A generalized vertex model with vertices and weights derived from the te…
Testing importance sampling on a quantum annealer for strong coupling SU(3) gauge theory
Jangho Kim, Thomas Luu, Wolfgang Unger
gauge theories in the strong coupling limit can be described by integer variables representing monomers, dimers and baryon loops. We demonstrate how the D-wave quantum an…
