Structure Formation With a Long-Range Scalar Dark Matter Interaction
Adi Nusser, S. S. Gubser, P. J. E. Peebles
Numerical simulations show that a long-range scalar interaction in a single species of massive dark matter particles causes voids between the concentrations of large galaxies to be…
Thermodynamics of R-charged Black Holes in AdS(5) From Effective Strings
Steven S. Gubser, Jonathan J. Heckman
It is well known that the thermodynamics of certain near-extremal black holes in asymptotically flat space can be lifted to an effective string description created from the interse…
The Gregory-Laflamme instability for the D2-D0 bound state
Steven S. Gubser
The D2-D0 bound state exhibits a Gregory-Laflamme instability when it is sufficiently non-extremal. If there are no D0-branes, the requisite non-extremality is finite. When most of…
Variations on the Warped Deformed Conifold
Steven S. Gubser, Christopher P. Herzog, Igor R. Klebanov
The warped deformed conifold background of type IIB theory is dual to the cascading gauge theory. We show that this background realizes the (super-)Goldst…
Cosmology with a dynamically screened scalar interaction in the dark sector
Steven S. Gubser, P. J. E. Peebles
Motivated in part by string theory, we consider a modification of the LambdaCDM cosmological model in which the dark matter has a long-range scalar force screened by light particle…
Symmetry Breaking and Axionic Strings in the Warped Deformed Conifold
Steven S. Gubser, Christopher P. Herzog, Igor R. Klebanov
We interpret D-strings at the bottom of the warped deformed conifold as axionic strings in the dual cascading SU(N+M) x SU(N) gauge theory. The axion is a massless pseudo-scalar gl…
