    • Algebraic Charge Liquids 

      Kaul, Ribhu; Kim, Yong; Sachdev, Subir; Senthil, T. (Nature Publishing Group, 2008)
      High temperature superconductivity emerges in the cuprate compounds upon changing the electron density of an insulator in which the electron spins are antiferromagnetically ordered. A key characteristic of the superconductor ...

    • Charge Fractionalization in Quantum Wires 

      Steinberg, Hadar; Barak, Gilad; Yacoby, Amir; Pfeiffer, Loren N.; West, Ken W.; Halperin, Bertrand; Le Hur, Karyn (Nature Publishing Group, 2008)
      Although the unit of charge in nature is a fundamental constant, the charge of individual quasiparticles in some low-dimensional systems may be fractionalized. Quantum one-dimensional (1D) systems, for instance, are ...

    • Mechanics of Individual, Isolated Vortices in a Cuprate Superconductor 

      Auslaender, Ophir M.; Luan, Lan; Straver, Eric W. J.; Hoffman, Jennifer; Koshnick, Nicholas C.; Zeldov, Eli; Bonn, Douglas A.; Liang, Ruixing; Hardy, Walter N.; Moler, Kathryn A. (Nature Publishing Group, 2009)
      Superconductors often contain quantized microscopic whirlpools of electrons, called vortices, that can be modelled as one-dimensional elastic objects1. Vortices are a diverse area of study for condensed matter because of ...

    • Quantum Magnetism and Criticality 

      Sachdev, Subir (Nature Publishing Group, 2008)
      Magnetic insulators have proved to be fertile ground for studying new types of quantum many body states, and I survey recent experimental and theoretical examples. The insights and methods transfer also to novel superconducting ...
