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…
Searching for the QCD critical endpoint using multi-point Padé approximations
David A. Clarke, Petros Dimopoulos, Francesco Di Renzo +4
Using the multi-point Padé approach, we locate Lee-Yang edge singularities of the QCD pressure in the complex baryon chemical potential plane. These singularities are extracted fro…
Searching for the QCD critical point using Lee-Yang edge singularities
D. A. Clarke, P. Dimopoulos, F. Di Renzo +4
Using QCD calculations at physical quark mass and purely imaginary baryon chemical potential, we locate Lee-Yang edge singularities in the complex chemical potential plan…
Detecting Lee-Yang/Fisher singularities by multi-point Padè
F. Di Renzo, D. A. Clarke, P. Dimopoulos +4
The Bielefeld Parma Collaboration has in recent years put forward a method to probe finite density QCD by the detection of Lee-Yang singularities. The location of the latter is obt…
Universal scaling and the asymptotic behaviour of Fourier coefficients of the baryon-number density in QCD
Christian Schmidt, David A. Clarke, Petros Dimopoulos +5
We discuss the scaling of the Yang-Lee singularity (YLs) and show how the universal scaling can be used to locate phase transitions in QCD. We describe two complementary methods to…
Exploring the Critical Points in QCD with Multi-Point Padé and Machine Learning Techniques in (2+1)-flavor QCD
Jishnu Goswami, D. A. Clarke, P. Dimopoulos +4
Using simulations at multiple imaginary chemical potentials for -flavor QCD, we construct multi-point Padé approximants. We determine the singularties of the Padé approximan…
