CM Seminar: Complexity in Josephson Matter, Charles Marcus, University of Washington
April 3 @ 8:00 am - 5:00 pm
Speaker: Charles Marcus, University of Washington
Time: 10:00-11:00am
Location: BRIM 311
Abstract: Hybrid superconductors-semiconductor heterostructures allow voltage control of carrier density in superconducting systems. We use these materials to investigate novel gate-controlled arrays of Josephson junctions in a variety of geometries, examining the interplay of quantum coherence, Coulomb interaction, and frustration. Using the example of the dice lattice, I will draw connections between protected quantum information and quantum phase transitions in two dimensions.
