Eigenvalues of the QCD Dirac matrix with improved staggered quarks in the continuum limit

Olaf Kaczmarek, Ravi Shanker, Sayantan Sharma

We calculate the eigenmodes of the Highly Improved Staggered Quark (HISQ) matrix near the chiral crossover transition in QCD with $2+1$ flavors with the aim to gain more insights i…
