Exponential reduction of the sign problem at finite density in the 2+1D XY model via contour deformations
Matteo Giordano, Kornel Kapas, Sandor D Katz +2
We study the 2+1 dimensional XY model at nonzero chemical potential on deformed integration manifolds, with the aim of alleviating its sign problem. We investigate several prop…
New approach to lattice QCD at finite density: reweighting without an overlap problem
Attila Pasztor, Szabolcs Borsanyi, Zoltan Fodor +5
Approaches to finite baryon density lattice QCD usually suffer from uncontrolled systematic uncertainties in addition to the well-known sign problem. We test a method - sign reweig…
New approach to lattice QCD at finite density; results for the critical end point on coarse lattices
Matteo Giordano, Kornel Kapas, Sandor D. Katz +2
All approaches currently used to study finite baryon density lattice QCD suffer from uncontrolled systematic uncertainties in addition to the well-known sign problem. We formulate…
The effect of stout smearing on the phase diagram from multiparameter reweigthing in lattice QCD
Matteo Giordano, Kornel Kapas, Sandor D. Katz +2
The phase diagram and the location of the critical endpoint (CEP) of lattice QCD with unimproved staggered fermions on a lattice was determined fifteen years ago with the m…
Radius of convergence in lattice QCD at finite with rooted staggered fermions
Matteo Giordano, Kornel Kapas, Sandor D. Katz +2
In typical statistical mechanical systems the grand canonical partition function at finite volume is proportional to a polynomial of the fugacity . The zero of this Lee-Ya…
Searching for a CEP signal with lattice QCD simulations
Zoltan Fodor, Matteo Giordano, Jana N. Guenther +7
We discuss the reliability of available methods to constrain the location of the QCD critical endpoint with lattice simulations. In particular we calculate the baryon fluctuations…
