    • 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, Djordje; 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 ...

      Dunn, Jay P.; Arav, Nahum; Aoki, Kentaro; Wilkins, Ashlee; Laughlin, Courtney; Edmonds, Douglas; Bautista, Manuel (IOP Publishing Ltd., 2012-05)
      We present a study of broad absorption line (BAL) quasar outflows that show S IV lambda 1063 and S IV* lambda 1073 troughs. The fractional abundances of S IV and C IV peak at similar value of the ionization parameter, ...
    • BAL phosphorus abundance and evidence for immense ionic column densities in quasar outflows: vlt/x-shooter observations of quasar SDSS J1512+1119

      We present spectroscopic analysis of the broad absorption line (BAL) outflow in quasar SDSS J1512+1119. In particular, we focus our attention on a kinematic component in which we identify P V and S IV/S IV* absorption ...

      Chang, Lay Nam; Lewis, Zachary; Minic, Djordje; Takeuchi, Tatsu; Tze, Chia-Hsiung (Hindawi Publishing Corporation, 2011)
      We offer an interpretation of superquantum correlations in terms of a “doubly” quantum theory.We argue that string theory, viewed as a quantum theory with two deformation parameters, the string tension α', and the string ...

      Chang, Lay Nam; Lewis, Zachary; Minic, Djordje; Takeuchi, Tatsu (Iop Publishing Ltd, 2013-12-06)
      We propose mutant versions of quantum mechanics constructed on vector spaces over the finite Galois fields GF(3) and GF(9). The mutation we consider here is distinct from what we proposed in previous papers on Galois field ...

    • Boson core compressibility 

      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 ...
    • Boundary Effects on Population Dynamics in Stochastic Lattice Lotka-Volterra Models 

      Heiba, B.; Chen, S.; Täuber, Uwe C.
      We investigate spatially inhomogeneous versions of the stochastic Lotka-Volterra model for predator-prey competition and coexistence by means of Monte Carlo simulations on a two-dimensional lattice with periodic boundary ...
    • Bounds on cosmic ray-boosted dark matter in simplified models and its corresponding neutrino-floor 

      Dent, James B.; Dutta, Bhaskar; Newstead, Jayden L.; Shoemaker, Ian M. (2020-06-15)
      We study direct detection bounds on cosmic ray-upscattered dark matter in simplified models including light mediators. We find that the energy dependence in the scattering cross section is significant, and produces stronger ...
    • Breathing dynamics in heteropolymer DNA 

      Ambjornsson, T.; Banik, S. K.; Krichevsky, O.; Metzler, R. (CELL PRESS, 2007-04)
      While the statistical mechanical description of DNA has a long tradition, renewed interest in DNA melting from a physics perspective is nourished by measurements of the fluctuation dynamics of local denaturation bubbles ...
    • A Calabi-Yau database: threefolds constructed from the Kreuzer-Skarke list
