Multi-Scale Physics from Multi-Braneworlds
S. Mouslopoulos
This Thesis presents a study of higher dimensional brane-world models with non-factorizable geometry. It is shown that in the context of multi-brane world constructions with locali…
D-Branes in Topological Membranes
P. Castelo Ferreira, I. I. Kogan, R. J. Szabo
It is shown how two-dimensional states corresponding to D-branes arise in orbifolds of topologically massive gauge and gravity theories. Brane vertex operators naturally appear in…
Hagedorn Inflation: Open Strings on Branes Can Drive Inflation
Steven Abel, Katherine Freese, Ian Kogan
We demonstrate an inflationary solution to the cosmological horizon problem during the Hagedorn regime in the early universe. Here the observable universe is confined to three spat…
Spherically symmetric spacetimes in massive gravity
Thibault Damour, Ian I. Kogan, Antonios Papazoglou
We explore spherically symmetric stationary solutions, generated by ``stars'' with regular interiors, in purely massive gravity. We reexamine the claim that the resummation of non-…
Ghost-Matter Mixing and Feigenbaum Universality in String Theory
Ian I. Kogan, Dimitri Polyakov
Brane-like vertex operators, defining backgrounds with the ghost-matter mixing in NSR superstring theory, play an important role in a world-sheet formulation of D-branes and M theo…
DBI Action from Closed Strings and D-brane second Quantization
Ian I. Kogan, Dimitri Polyakov
Brane-like vertex operators play an important role in a worldsheet formulation of D-branes and M-theory. In this paper we derive the DBI D-brane action from NSR closed string sigma…
