Rigorous arguments against current wisdoms in finite density QCD
R. Aloisio, V. Azcoiti, G. Di Carlo +2
QCD at finite chemical potential is analytically investigated in the region of large bare fermion masses. We show that, contrary to the general wisdom, the phase of the fermion det…
Finite density QCD with heavy quarks
R. Aloisio, V. Azcoiti, G. Di Carlo +2
In the large fermion mass limit of QCD at finite density the structure of the partition function greatly simplifies and can be studied analytically. We show that, contrary to gener…
Phase transition(s) in finite density QCD
R. Aloisio, V. Azcoiti, G. Di Carlo +2
The Grand Canonical formalism is generally used in numerical simulations of finite density QCD since it allows free mobility in the chemical potential . We show that special car…
Frustration in Finite Density QCD
R. Aloisio, V. Azcoiti, G. Di Carlo +2
We present a detailed analysis of the QCD partition function in the Grand Canonical formalism. Using the fugacity expansion we find evidence for numerical instabilities in the stan…
Investigation of a Toy Model for Frustration in Abelian Lattice Gauge Theory
V. Azcoiti, G. Di Carlo, E. Follana
We introduce a lattice model with local U(1) gauge symmetry which incorporates explicit frustration in d >2. The form of the action is inspired from the loop expansion of the fermi…
First Order Phase Transition in Finite Density QCD using the modulus of the Dirac Determinant
R. Aloisio, V. Azcoiti, G. Di Carlo +2
We report results of simulations of strong coupling, finite density QCD obtained within a MFA inspired approach where the fermion determinant in the integration measure is replaced…
