A comparison of spectral reconstruction methods applied to non-zero temperature NRQCD meson correlation functions
Thomas Spriggs, Gert Aarts, Chris Allton +9
We present results from the fastsum collaboration's programme to determine the spectrum of the bottomonium system as a function of temperature. Three different methods of extractin…
Sp(4) gauge theories and beyond the standard model physics
Biagio Lucini, Ed Bennett, Jack Holligan +7
We review numerical results for models with gauge group Sp(2N), discussing the glueball spectrum in the large-N limit, the quenched meson spectrum of Sp(4) with Dirac fermions in t…
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…
Efficient computations of continuous action densities of states for lattice models
Biagio Lucini, Olmo Francesconi, Markus Holzmann +2
The Logarithmic Linear Relaxation (LLR) algorithm is an efficient method for computing densities of states for systems with a continuous spectrum. A key feature of this method is e…
Inverse Renormalization Group in Quantum Field Theory
Dimitrios Bachtis, Gert Aarts, Francesco Di Renzo +1
We propose inverse renormalization group transformations within the context of quantum field theory that produce the appropriate critical fixed point structure, give rise to invers…
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…
