Conformality in many-flavour lattice QCD at strong coupling
Philippe de Forcrand, Seyong Kim, Wolfgang Unger
It is widely believed that chiral symmetry is spontaneously broken at zero temperature in the strong coupling limit of staggered fermions, for any number of colors and flavors. Usi…
Walking near a Conformal Fixed Point: the 2-d O(3) Model at theta near pi as a Test Case
Philippe de Forcrand, Michele Pepe, Uwe-Jens Wiese
Slowly walking technicolor models provide a mechanism for electroweak symmetry breaking whose nonperturbative lattice investigation is rather challenging. Here we demonstrate walki…
Numerical properties of staggered quarks with a taste-dependent mass term
Philippe de Forcrand, Aleksi Kurkela, Marco Panero
The numerical properties of staggered Dirac operators with a taste-dependent mass term proposed by Adams [1,2] and by Hoelbling [3] are compared with those of ordinary staggered an…
Constraints on the two-flavor QCD phase diagram from imaginary chemical potential
Claudio Bonati, Philippe de Forcrand, Massimo D'Elia +2
We review our knowledge of the phase diagram of QCD as a function of temperature, chemical potential and quark masses. The presence of tricritical lines at imaginary chemical poten…
