Testing machine-learned distributions against Monte Carlo data for the QCD chiral phase transition
Reinhold Kaiser, Frithjof Karsch, Jan Philipp Klinger +3
We demonstrate that conditional Masked Autoregressive Flows constitute a flexible interpolation tool for lattice QCD observables, conditioned on bare lattice parameters. As a bench…
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…
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 Lee-Yang and Fisher Zeros in the 2D Ising model through multipoint Padé approximants
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…
Lee-Yang and Langer edge singularities from analytic continuation of scaling functions
Frithjof Karsch, Christian Schmidt, Simran Singh
We discuss the analytic continuation of scaling function in the 3-dimensional Z(2),O(2) andO(4) universality classes using the Schofield representation of the magnetic equation of…
Determination of Lee-Yang edge singularities in QCD by rational approximations
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…
Multi-point Padè for the study of phase transitions: from the Ising model to lattice QCD
Francesco Di Renzo, Simran Singh
The Bielefeld Parma collaboration has recently put forward a method to investigate the QCD phase diagram based on the computation of Taylor series coefficients at both zero and ima…
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…
Thimble regularisation of YM fields: crunching a hard problem
Francesco Di Renzo, Simran Singh, Kevin Zambello
Thimble regularisation of Yang Mills theories is still to a very large extent terra incognita. We discuss a couple of topics related to this big issue. 2d YM theories are in princi…
Taylor expansions and Padé approximations for Lefschetz thimbles and beyond
Kevin Zambello, Francesco Di Renzo, Simran Singh
Deforming the domain of integration after complexification of the field variables is an intriguing idea to tackle the sign problem. In thimble regularization the domain of integrat…
Lee-Yang edge singularities in 2+1 flavor QCD with imaginary chemical potential
Guido Nicotra, Petros Dimopoulos, Lorenzo Dini +6
We present results of the location of the closest singularities in the complex chemical potential plane using a novel method. These results are obtained with (2+1)-flavor of highly…
Lee-Yang edge singularities in lattice QCD : A systematic study of singularities in the complex plane using rational approximations
Simran Singh, Petros Dimopoulos, Lorenzo Dini +6
A new approach is presented to explore the singularity structure of lattice QCD at imaginary chemical potential. Our method can be seen as a combination of the Taylor expansion and…
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…
One-thimble regularisation of lattice field theories: is it only a dream?
Francesco Di Renzo, Simran Singh, Kevin Zambello
Lefschetz thimbles regularisation of (lattice) field theories was put forward as a possible solution to the sign problem. Despite elegant and conceptually simple, it has many subtl…
