A novel framework for spectral density reconstruction via quadrature-based Laplace inversion
Marco Aliberti, Francesco Di Renzo, Petros Dimopoulos +1
In this work, we explore a numerical approach for performing the inverse Laplace transformation, with an emphasis on achieving stability and robustness under noisy conditions. Our…

On analytic continuation from imaginary to real chemical potential in Lattice QCD
Francesco Di Renzo, Marco Aliberti, Petros Dimopoulos
Imaginary baryon number chemical potential simulations are a popular workaround for the (in)famous sign problem plaguing finite density QCD studies on the lattice. One is necessari…
