New Dirac Point Created in Graphene

Graphene, a two-dimensional lattice of hexagonally bonded carbon atoms, continues to be a hot topic in condensed matter physics. The LeRoy and Jacquod research groups have discovered that when graphene is placed on boron nitride, six new Dirac cones are created. The interaction between the graphene and boron nitride leads to the emergence of new quasiparticles with significantly reduced and anisotropic velocities. The research has been recently published in Nature Physics.

Higgs Boson Update

The search for the Higgs boson, which has spanned decades and continents, may be coming to an end. Results from the Large Hadron Collider at CERN and the Tevatron at Fermilab indicate that if the Higgs exists, it must have a mass near 125 GeV. Among the contributors to the Tevatron results were postdoc Xiaowen Lei and professor Erich Varnes. Continued analysis and further data from the LHC should settle the issue of the Higgs' existence by the end of the year.
