The MgII Cross-section of Luminous Red Galaxies
David V. Bowen, Doron Chelouche
We describe a search for MgII(2796,2803) absorption lines in Sloan Digital Sky Survey (SDSS) spectra of QSOs whose lines of sight pass within impact parameters of 200 kpc of galaxi…
On Stably free modules over Laurent polynomial rings
Abed Abedelfatah
We prove constructively that for any finite-dimensional commu- tative ring R, every stably free module over R[X;X^{1}] of rank > dim R is free, i.e., R[X;X^{-1}] is (dimR)-Hermite.
p-wave Holographic Superconductors and five-dimensional gauged Supergravity
Francesco Aprile, Diego Rodriguez-Gomez, Jorge G. Russo
We explore five-dimensional and SO(6) gauged supergravities as frameworks for condensed matter applications. These theories contain cha…
Toric CFTs, Permutation Triples, and Belyi Pairs
Vishnu Jejjala, Sanjaye Ramgoolam, Diego Rodriguez-Gomez
Four-dimensional CFTs dual to branes transverse to toric Calabi-Yau threefolds have been described by bipartite graphs on a torus (dimer models). We use the theory of dessins d'enf…
Magneto-roton excitation in a holographic quantum Hall fluid
Niko Jokela, Gilad Lifschytz, Matthew Lippert
We compute the neutral bosonic excitation spectra of the holographic quantum Hall fluid described by the D3-D7' system. We find that the system is stable, gapped, and, in a range o…
Death of soliton trains in attractive Bose-Einstein condensates
Alexej I. Streltsov, Ofir. E. Alon, Lorenz S. Cederbaum
Experiments on ultra-cold attractive Bose-Einstein Condensates (BECs) have demonstrated that at low dimensions atomic clouds can form localized objects, propagating for long times…
