Computing general observables in lattice models with complex actions
Olmo Francesconi, Markus Holzmann, Biagio Lucini +2
The study of QFTs at finite density is hindered by the presence of the so-called sign problem. The action definition of such systems is, in fact, complex-valued making standard imp…
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…
