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…
