With complex Langevin towards the QCD phase diagram

  • Event time: 2:00pm until 3:00pm
  • Event date: 30th March 2022
  • Speaker: Felix Ziegler (Formerly School of Physics & Astronomy, University of Edinburgh)
  • Location: Higgs Centre Seminar Room, Room 4305,

Event details

We explore the QCD phase diagram on the lattice over a large range of chemical potentials and temperatures using the complex Langevin method. For our simulations, we use two flavours of dynamical Wilson fermions with a pion mass of approximately 480 MeV. Here we report on consistency checks at zero chemical potential and present results for the fermion density, the deconfinement transition and the equation of state. We observe that at the lowest temperature the fermion density remains zero up to a third of the nucleon mass, in line with the expectations from the Silver Blaze phenomenon.
