Metal-insulator transition and engineering of extended states in disordered systems beyond one dimension
Abstract
We shall discuss how to engineer wave function delocalization in disordered systemsmodeled by tight binding Hamiltonians in d > 1 dimensions. Exact analytical results willbe presented for the case of a two legged ladder network infinitely large along the x-axis,revealing how it can finally be used as a switching device. The results persist even whenthe ladder expands in the transverse direction, making a journey towards a real twodimensional system. The study gives rise to the possibility of designing disorderedpotentials that might work as band-pass filters for quantum waves, such as matter wavesin optical lattices.
Superconductivity centennial and 2011 APS march meeting
Abstract
The 2011 APS March meeting was held in Dallas, USA during 21-25 march. It commemorated 100 years of superconductivity. Observation of vortex lattice related anomalies in polycrystalline YBa2Cu3O7-x near Tc was presented in the meeting.
