Numerical methods for the sign problem in Lattice Field Theory
Lorenzo Bongiovanni
The great majority of algorithms employed in the study of lattice field theory are based on Monte Carlo's importance sampling method, i.e. on probability interpretation of the Bolt…
The density of states approach at finite chemical potential: a numerical study of the Bose gas
L. Bongiovanni, K. Langfeld, B. Lucini +2
Recently, a novel algorithm for computing the density of states in statistical systems and quantum field theories has been proposed. The same method can be applied to theories at f…
The density of states approach for the simulation of finite density quantum field theories
K. Langfeld, B. Lucini, A. Rago +2
Finite density quantum field theories have evaded first principle Monte-Carlo simulations due to the notorious sign-problem. The partition function of such theories appears as the…
Complex Langevin dynamics for SU(3) gauge theory in the presence of a theta term
Lorenzo Bongiovanni, Gert Aarts, Erhard Seiler +1
One of the yet unsolved questions of QCD in the context of the Standard Model is to explain the strong CP problem. A way to look for a better understanding of it is to investigate…
Some remarks on Lefschetz thimbles and complex Langevin dynamics
Gert Aarts, Lorenzo Bongiovanni, Erhard Seiler +1
Lefschetz thimbles and complex Langevin dynamics both provide a means to tackle the numerical sign problem prevalent in theories with a complex weight in the partition function, e.…
Adaptive gauge cooling for complex Langevin dynamics
Lorenzo Bongiovanni, Gert Aarts, Erhard Seiler +2
In the case of nonabelian gauge theories with a complex weight, a controlled exploration of the complexified configuration space during a complex Langevin process requires the use…
