We measure the low lying eigenmodes of an overlap Dirac operator on 2–flavor staggered configurations. By comparing the eigenmode distribution to the predictions of Random Matrix Theory we test to what accuracy staggered configurations describe continuum QCD. The agreement between the numerical data and RMT implies that at our quark mass values the lattice artifacts of the staggered configurati...

The rooted staggered determinant in the Schwinger model

We investigate the continuum limit of the rooted staggered action in the 2-dimensional Schwinger model. We match both the unrooted and rooted staggered determinants with an overlap fermion determinant of two (one) flavors and a local pure gauge effective action by fitting the coefficients of the effective action and the mass of the overlap operator. The residue of this fit measures the differen...

Thermodynamics second law and ω = −1 crossing(s) in interacting holographic dark energy model Abstract By the assumption that the thermodynamics second law is valid, we study the possibility of ω = −1 crossing in an interacting holographic dark energy model. We show that this crossing is possible provided we choose appropriate parameters for the system.
