Varró Sándor - The 110 Years of the Photon. From Einstein’s Light Quanta to Extreme Light

2015. november 17.
MTA Wigner FK SZFI, I. épület
We review the historical background and variants of the notion of light quanta since Einstein’s “heuristic viewpoint” on the photoelectric effect was published in 1905.

Halász Gábor - Hole dynamics in exactly solvable gapped and gapless spin liquids

2015. november 10
MTA Wigner FK SZFI, I. épület
We present a controlled microscopic study of hole dynamics in both a gapped and a gapless spin liquid. Our approach is complementary to previous phenomenological works as we introduce mobile holes into the spin liquid ground state of the exactly solvable Kitaev honeycomb model.

Ken Elder - Honeycomb and Triangular Domain Wall Networks in Heteroepitaxial Systems

2015. szeptember 15.
MTA Wigner FK, I. épület
In this talk I would like to present a  study of the influence of misfit strain, adhesion strength, and lattice symmetry on the complex Moire patterns that form in ultrathin films adsorbed on compact triangular surfaces, such as graphene on metals.
