Towards more accurate and form factors
Logan Roberts, Chris Bouchard, Olmo Francesconi +1
We present progress on the calculation of scalar, vector, and tensor form factors for the following meson decays: , , and $D_s\righ…
LapH interpolating fields with open boundary conditions
Michele Della Morte, Olmo Francesconi, Justus Tobias Tsang
The stochastic Laplacian Heaviside (LapH) method has proven to be successful in hadronic calculations. In this work, with charm-light spectroscopy in mind, we set up and optimise t…
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…
Calculation of the running coupling in non-Abelian gauge theories from Jarzynski's equality
Olmo Francesconi, Marco Panero, David Preti
We discuss the theoretical foundations of non-equilibrium Monte Carlo simulations based on Jarzynski's equality and present, as an example of application, the determination of the…
Strong coupling from non-equilibrium Monte Carlo simulations
Olmo Francesconi, Marco Panero, David Preti
We compute the running coupling of non-Abelian gauge theories in the Schrödinger-functional scheme, by means of non-equilibrium Monte Carlo simulations on the lattice.
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…
