    • Fractional and integer quantum Hall effects in the zeroth Landau level in graphene 

      Abanin, Dmitry A.; Feldman, Benjamin E.; Yacoby, Amir; Halperin, Bertrand I. (American Physical Society, 2013)
      Experiments on the fractional quantized Hall effect in the zeroth Landau level of graphene have revealed some striking differences between filling factors in the ranges 0 < vertical bar nu vertical bar < 1 and 1 < ...

    • Measuring Entanglement Entropy of a Generic Many-Body System with a Quantum Switch 

      Abanin, Dmitry A.; Demler, Eugene (American Physical Society, 2012)
      Entanglement entropy has become an important theoretical concept in condensed matter physics because it provides a unique tool for characterizing quantum mechanical many-body phases and new kinds of quantum order. However, ...

    • Quantum Hall Conductance of Two-Terminal Graphene Devices 

      Williams, James R.; Abanin, Dmitry A.; DiCarlo, Leonardo; Levitov, Leonid S.; Marcus, Charles Masamed (American Physical Society, 2009)
      Measurement and theory of the two-terminal conductance of monolayer and bilayer graphene in the quantum Hall regime are compared. We examine features of conductance as a function of gate voltage that allow monolayer, ...

    • Time-Dependent Impurity in Ultracold Fermions: Orthogonality Catastrophe and Beyond 

      Knap, Michael; Shashi, Aditya; Nishida, Yusuke; Imambekov, Adilet; Abanin, Dmitry A.; Demler, Eugene (American Physical Society, 2012)
      The recent experimental realization of strongly imbalanced mixtures of ultracold atoms opens new possibilities for studying impurity dynamics in a controlled setting. In this paper, we discuss how the techniques of atomic ...
