 COMPLETE LIST 

DATE: 20-01-2011

LABORATORI NAZIONALI DI FRASCATI
Giovedi' 20 Gennaio, 2011 ore 15:00 Aula B. Touschek Laboratori Nazionali di Frascati Via Enrico Fermi 40, Frascati SEMINARIO PROF. VITTORIO PELLEGRINI (Scuola Normale Superiore Pisa) Abstract The ability to isolate Graphene, a one-atom-thick two-dimensional crystal made by carbon atoms arranged in a honeycomb pattern, and control its electrical properties [1] has led to a revolution in material science and condensed matter physics [2]. Electrons in graphene behave as massless Dirac fermions, the role of the speed of light c being played by the Fermi velocity vF ≈ c/300 [3]. This essential feature of electrons in graphene derives from its unusual linear band dispersion [4], ultimately stemming from the underlying honeycomb topology. This basic solid-state effect has led to the unique possibility to test quantum relativistic phenomena in table-top experiments [5]. In the first part of the talk I will review the salient properties of graphene, summarize the main directions of fundamental and applied research and present recent results obtained by our group [6,7]. In the second part of the talk I’ll focus on the issue of spontaneous symmetry breaking effects linked to lattice-scale order. These many-body phenomena yield unusual ground states where Dirac quasiparticles are non-uniformly distributed between the two triangular sub-lattices forming the honeycomb pattern [8]. I’ll show how these phenomena can be simulated in nanofabricated artificial lattices with honeycomb topology [9,10,11].
