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…
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…
Nuclear Liquid-Gas Transition in the Strong Coupling Regime of Lattice QCD
Jangho Kim, Pratitee Pattanaik, Wolfgang Unger
The nuclear liquid-gas transition from a gas of hadrons to a nuclear phase cannot be determined numerically from conventional lattice QCD due to the severe sign problem at large va…
Towards Quantum Monte Carlo Simulations at non-zero Baryon and Isospin Density in the Strong Coupling Regime
Pratitee Pattanaik, Wolfgang Unger
The Hamiltonian formulation of Lattice QCD with staggered fermions in the strong coupling limit has no sign problem at non-zero baryon density and allows for Quantum Monte Carlo si…
Nuclear Transition in the Strong Coupling Limit
Jangho Kim, Pratitee Pattanaik, Wolfgang Unger
Lattice QCD at finite baryon chemical potential has the infamous sign problem which hinders Monte Carlo simulations. This can be remedied by a dual representation that makes the si…
Hamiltonian Lattice QCD from Strong Coupling Expansion
Pratitee Pattanaik, Wolfgang Unger
We present generalizations of Hamiltonian Lattice QCD as derived from the continuous time limit of strong coupling lattice QCD: we discuss the flavor dependence and the effect of g…
