We present preliminary results of B K calculated using improved staggered fermions with the mixed action (valence quarks = HYP staggered fermions and sea quarks = AsqTad staggered fermions). We analyze the data based upon the prediction by Van de Water and Sharpe. A hint of consistency with the prediction is observed. We also present preliminary results of B ¡ 3¢ 2£ 8 and B ¡ 3¢ 2£ 7 .

Majorana fermions are quasiparticle excitations which are features of a two-dimensional quantum system in a so-called topological phase. Majorana fermions are non-Abelian anyons and the system therefore has a degenerate groundstate protected by a gap to the other excitations. It has been proposed that a system with Majorana fermions can be utilized for performing fault-tolerant quantum computat...

1. Abstract We analyse − within the hamiltonian formalism with staggered fermions − the patterns of chiral symmetry breaking for the strongly coupled Schwinger and U (N c)-color 't Hooft models with one and two flavor of fermions. Using the correspondence between these strongly coupled gauge models and antiferromagnetic spin chains, we provide a rather intuitive picture of their ground states, ...

We introduce an index indicating the occurrence of chiral fermions at the intersection of branes in matrix models. This allows to discuss the stability of chiral fermions under perturbations of the branes.

A bstract Celestial diamonds encode the global conformal multiplets of conformally soft sector, elucidating role theorems, symmetry generators and Goldstone modes. Upon adding supersymmetry they stack into a pyramid. Here we treat charges associated to fermionic layers that tie this structure together. This extends analysis currents for photons gravitons which have been shown generate asymptoti...
