      Massano, William J.; Bowen, Samuel P.; Mancini, Jay D. (American Physical Society, 1989-04)
      We use the connected-moment expansion, recently developed by Cioslowski [Phys. Rev. Lett. 58, 83 (1987)], to investigate the ground-state energy of the single-impurity Anderson model. It is found that the moment expansion ...

    • B-branes and supersymmetric quivers in 2d 

      Closset, Cyril; Guo, Jirui; Sharpe, Eric R. (Springer, 2018-02-08)
      We study 2d N = (0, 2) supersymmetric quiver gauge theories that describe the low-energy dynamics of D1-branes at Calabi-Yau fourfold (CY4) singularities. On general grounds, the holomorphic sector of these theories - ...
    • Background independent quantum mechanics and gravity 

      Minic, D.; Tze, C. H. (American Physical Society, 2003-09-15)
      We argue that the demand of background independence in a quantum theory of gravity calls for an extension of standard geometric quantum mechanics. We discuss a possible kinematical and dynamical generalization of the latter ...

      Khorramzadeh, Y.; Lin, Fei; Scarola, Vito W. (American Physical Society, 2012-04-16)
      Strongly interacting atoms trapped in optical lattices can be used to explore phase diagrams of Hubbard models. Spatial inhomogeneity due to trapping typically obscures distinguishing observables. We propose that measures ...

      Slawny, Joseph A. (AIP Publishing, 2007-05)
      The following properties of bound states of hydrogen atom in a theory with noncommuting position operators are investigated: their number, multiplicities, accidental degeneracy, localization, and dependence on the values ...
