Abstract The phase diagram for staggered fermions is discussed in the context of the staggered chiral Lagrangian, extending previous work on the subject. When the discretization errors are significant, there may be an Aoki-like phase for staggered fermions, where the remnant SO(4) taste symmetry is broken down to SO(3). We solve explicitly for the mass spectrum in the 3-flavor degenerate mass c...

In studies of chiral symmetry breaking it is desirable to start from an (almost) chirally invariant formulation of lattice fermions. At present this is best realized by using fermions satisfying the Ginsparg-Wilson relation, e.g. using the overlap operator, or by working with the domain wall framework [1]. In such approaches Wilson fermions are still important as an input. For the Wilson-Dirac ...

We discuss the phase diagram of Wilson fermions in the m0–g 2 plane for twoflavor QCD. We argue that, as originally suggested by Aoki, there is a phase in which flavor and parity are spontaneously broken. Recent numerical results on the spectrum of the overlap Hamiltonian have been interpreted as evidence against Aoki’s conjecture. We show that they are in fact consistent with the presence of a...

A new oribatid mite genus, Chistyakovella gen. nov. (Carabodidae), with type species C. insolita sp. nov., is proposed and described from Southern Vietnam. It is clearly distinguished from other carabodid genera by the lamellae, which are touching medially. The new genus is most similar morphologically to Gibbicepheus Balogh, 1958 and Diplobodes Aoki, 1958, however it can be clearly distinguish...

1 Evaluation of security 1.1. Differential cryptanalysis In extending differential cryptanalysis, Aoki , Kobayashi, and Moriai [1] greatly reduced the computational amount needed [2]. They determined that differential cryptanalysis could not be applied to FEAL with more than 32 rounds. Biham et al. [3] proposed a new cyptanalysis of Skipjack [4] using impossible differentials. Although regular ...
