We introduce a new domain wall operator that represents a full (real) Möbius transformation of a given non-chiral Dirac kernel. Shamir's and Chiu/Boriçi's domain wall fermions are special cases of this new class. By tuning the parameters of the Möbius operator and by introducing a new Red/Black preconditioning, we are able to reduce the computational effort substantially.

We discuss the adaptation of the Hybrid Monte Carlo algorithm to overlap fermions. We derive a method which can be used to account for the delta function in the fermionic force caused by the differential of the sign function. We discuss the algoritmic difficulties that have been overcome, and mention those that still need to be solved.

We have studied the 3-flavor, finite temperature, QCD phase transition with staggred fermions on an Nt = 4 lattice. By studying a variety of quark masses we have located the critical point, mc, where the first order 3-flavor transition ends as lying in the region 0.32 ≤ mc ≤ 0.35 in lattice units.
