News from bottomonium spectral functions in thermal QCD
Sam Offler, Gert Aarts, Chris Allton +6
New results on bottomonium at nonzero temperature are presented, using the FASTSUM Generation 2L ensembles. Preliminary results for spectral function reconstruction using Kernel Ri…
Spectral quantities in thermal QCD: a progress report from the FASTSUM collaboration
Gert Aarts, Chris Allton, Jonas Glesaaen +8
In order to study spectral quantities in thermal QCD, the FASTSUM collaboration employs anisotropic lattice simulations with N_f=2+1 flavours of Wilson fermions. Here we discuss ou…
Meson spectrum of Sp(4) lattice gauge theory with two fundamental Dirac fermions
Ed Bennett, Deog Ki Hong, Jong-Wan Lee +4
We calculate the meson spectrum of the Sp(4) lattice gauge theory coupled to two fundamental flavours of dynamical Dirac fermions. We focus on some of the lightest (flavoured) spin…
Free energy of the self-interacting relativistic lattice Bose gas at finite density
Olmo Francesconi, Markus Holzmann, Biagio Lucini +1
The density of state approach has recently been proposed as a potential route to circumvent the sign problem in systems at finite density. In this study, using the Linear Logarithm…
The density of states approach to the sign problem
Biagio Lucini, Olmo Francesconi, Markus Holzmann +1
Approaches to the sign problem based on the density of states have been recently revived by the introduction of the LLR algorithm, which allows us to compute the density of states…
