Speeding up Fermionic Lattice Calculations with Photonic Accelerated Inverters
Felipe Attanasio, Marc Bauer, Jelle Dijkstra +3
Lattice field theory (LFT) is the standard non-perturbative method to perform numerical calculations of quantum field theory. However, the typical bottleneck of fermionic lattice c…
Harmonically trapped fermions in one dimension: A finite temperature lattice Monte Carlo study
Felipe Attanasio, Marc Bauer, Renzo Kapust +1
We study a one-dimensional two-component Fermi gas in a harmonic trapping potential using finite temperature lattice quantum Monte Carlo methods. We are able to compute observables…
Low energy effective theories on the lattice with coloured noise
Felipe Attanasio, Jan Philipp Klinger, Jan M. Pawlowski
Low energy effective theories give access to regimes of the QCD phase diagram that to date are hard to simulate directly with lattice QCD or with functional approaches. For lattice…
