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…
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…

Simran Singh, Massimo Cipressi, Francesco Di Renzo
We present a numerical calculation of the Lee-Yang and Fisher zeros of the 2D Ising model using multi-point Padé approximants. We perform simulations for the 2D Ising model with fe…

Kevin Zambello, David A. Clarke, Petros Dimopoulos +5
We report updated results on the determination of Lee-Yang edge (LYE) singularities in QCD using highly improved staggered quarks (HISQ) with physical masses on $N_τ= 4…
Phase Transitions in Particle Physics -- Results and Perspectives from Lattice Quantum Chromo-Dynamics
Gert Aarts, Joerg Aichelin, Chris Allton +38
Phase transitions in a non-perturbative regime can be studied by ab initio Lattice Field Theory methods. The status and future research directions for LFT investigations of Quantum…
Probing the energy-smeared R-ratio on the lattice
Constantia Alexandrou, Simone Bacchio, Alessandro De Santis +15
We present a first-principles lattice QCD investigation of the -ratio between the cross-section into hadrons and that into muons. By using the method of Ref.[1], that a…
Detecting critical points from Lee-Yang edge singularities in lattice QCD
Christian Schmidt, David A. Clarke, Petros Dimopoulos +5
A new approach is presented to explore the singularity structure of lattice QCD in the complex chemical potential plane. Our method can be seen as a combination of the Taylor expan…

We present a lattice determination of the leading-order hadronic vacuum polarization (HVP) contribution to the muon anomalous magnetic moment, , in the so-called sho…
First moments of the nucleon transverse quark spin densities using lattice QCD
C. Alexandrou, S. Bacchio, M. Constantinou +9
We present a calculation of the Mellin moments of the transverse quark spin densities in the nucleon using lattice QCD. The densities are extracted from the unpolarized and transve…
Contribution to understanding the phase structure of strong interaction matter: Lee-Yang edge singularities from lattice QCD
P. Dimopoulos, L. Dini, F. Di Renzo +6
We present a calculation of the net baryon number density as a function of imaginary baryon number chemical potential, obtained with highly improved staggered quarks (HISQ) at temp…
Settling an old story: solution of the Thirring model in thimble regularization
Francesco Di Renzo, Kevin Zambello
Thimble regularisation of lattice field theories has been proposed as a solution to the infamous sign problem. It is conceptually very clean and powerful, but it is in practice lim…

Dimitrios Bachtis, Gert Aarts, Francesco Di Renzo +1
We propose inverse renormalization group transformations within the context of quantum field theory that produce the appropriate critical fixed point structure, give rise to invers…

We present a determination of the ratio of kaon and pion leptonic decay constants in isosymmetric QCD (isoQCD), , making use of the gauge ensembles produced by the Exten…
Taylor expansions on Lefschetz thimbles (and not only that)
Francesco Di Renzo, Simran Singh, Kevin Zambello
Thimble regularisation is a possible solution to the sign problem, which is evaded by formulating quantum field theories on manifolds where the imaginary part of the action stays c…
