Lattice Field Theory Analysis of the Chiral Heisenberg Model
Simon Hands, Johann Ostmeyer
Motivated by ongoing interest in the universal behaviour of the Hubbard model of spinning electrons on honeycomb and -flux lattices at the semi-metal -- Mott insulator phase tra…
Recent Results from the FASTSUM Collaboration
Chris Allton, Gert Aarts, Ryan Bignell +10
The FASTSUM Collaboration has developed a comprehensive research programme in thermal QCD using 2+1 flavour, anisotropic ensembles. In this talk, we summarise some of our recent re…
Spectroscopy in the 2+1 Thirring Model with Domain Wall Fermions
Simon Hands, Johann Ostmeyer
We employ the domain wall fermion (DWF) formulation of the Thirring model on a lattice in 2+1+1 dimensions and perform flavor Monte Carlo simulations. At a critical interacti…
Hadrons at high temperature: an update from the FASTSUM collaboration
Jon-Ivar Skullerud, Gert Aarts, Chris Allton +16
We present the most recent results from the FASTSUM collaboration for hadron properties at high temperature. This includes the temperature dependence of the light and charmed meson…
Thermal Transitions in Dense Two-Colour QCD
Dale Lawlor, Simon Hands, Seyong Kim +1
The infamous sign problem makes it impossible to probe dense (baryon density ) QCD at temperatures near or below the deconfinement threshold. As a workaround, one can explor…
Open charm mesons at nonzero temperature: results in the hadronic phase from lattice QCD
Gert Aarts, Chris Allton, Ryan Bignell +7
We study what happens to D and D_s mesons as the temperature increases, using lattice QCD simulations with N_f=2+1 dynamical flavours on anistropic lattices. We have access to five…
Properties of Overlap and Domain Wall Fermions in the 2+1D Thirring Model
Jude Worthy, Simon Hands
We present some results pertaining to partially quenched formulations of the overlap/domain wall operator with the Thirring model in 2+1D. Auxiliary fields are generated with a Sha…
Lattice QCD at nonzero temperature and density
G. Aarts, C. Allton, S. Hands +6
We discuss some selected recent developments in the field of lattice QCD at nonzero temperature and density, describing in particular the transition from the hadronic gas to the qu…
Meson thermal masses at different temperatures
Sergio Chaves García-Mascaraque, Gert Aarts, Chris Allton +3
We determine the ground state meson masses at low temperature using simulations with flavours of improved Wilson-clover fermions. Subsequently we study the effect of increasi…
Critical Behaviour in the Single Flavor Planar Thirring Model
Simon Hands, Michele Mesiti, Jude Worthy
We report results of simulations of the Thirring model with fermion flavors, defined on a lattice using domain wall fermions. This approach is devised to respect as far…
The Planar Thirring Model with Kähler-Dirac Fermions
Simon Hands
Kähler's geometric approach in which relativistic fermion fields are treated as differential forms is applied in three spacetime dimensions. It is shown that the resulting continuu…
Planar Thirring Model in the U(2)-symmetric limit
Simon Hands
I review the Thirring model in 2+1 dimensions, focussing in particular on possible strongly-interacting UV-stable fixed points of the renormalisation group, corresponding to a c…
Critical Behaviour in the Single Flavor Thirring Model in 2+1d
Simon Hands, Michele Mesiti, Jude Worthy
Results of a lattice field theory simulation of the single-flavor Thirring model in 2+1 spacetime dimensions are presented. The lattice model is formulated using domain wall fermio…
Mesonic correlators at non-zero baryon chemical potential

In order to study the fate of mesons in thermal QCD at finite baryon chemical potential, we consider light mesonic correlation functions using the Taylor expansion to ${\cal O}((μ/…
