The geometry of flat spacetime modded out by a null rotation (boost + rotation) is analysed. When embedding this quotient spacetime in String/M-theory, it still preserves one half of the original supersymmetries. Its connection with the BTZ black hole, supersymmetric dilatonic waves and one possible resolution of its singularity in terms of nullbranes are also discussed.

Flow of geometries and instantons on the null orbifold
We study condensation of twisted sector states in the null orbifold geometry. As the singularity is time-dependent, we probe it using D-Instantons. We present evidence that the null-orbifold flows toExpand
A Matrix Model for the Null-Brane
The null-brane background is a simple smooth 1/2 BPS solution of string theory. By tuning a parameter, this background develops a big crunch/big bang type singularity. We construct the DLCQExpand
Strings in the Extended BTZ Spacetime
We study string theory on the extended spacetime of the BTZ black hole, as described by an orbifold of the SL(2,) WZW model. The full spacetime has an infinite number of disconnected boundaryExpand
Instability of spacelike and null orbifold singularities
Time dependent orbifolds with spacelike or null singularities have recently been studied as simple models of cosmological singularities. We show that their apparent simplicity is an illusion: theExpand
Causal structure of d = 5 vacua and axisymmetric spacetimes
We study the structure of closed timelike curves (CTCs) for the near horizon limit of the five dimensional BMPV black hole, in its overrotating regime. We argue that Bousso's holographic screens areExpand
Time-dependent backgrounds in supergravity and string theory
Time-dependent solutions of supergravity and string theory are studied. The examples are obtained from de Sitter deformation of gauge-gravity dualities, analytical continuation of static solutions,Expand
Stringy Resolutions of Null Singularities
We study string theory in supersymmetric time-dependent backgrounds. In the framework of general relativity, supersymmetry for spacetimes without flux implies the existence of a covariantly constantExpand
Strings in extremal BTZ black holes
We study the spectrum of the worldsheet theory of the bosonic closed string in the massless and extremal rotating BTZ black holes. We use a hyperbolic Wakimoto representation of the SL(2,) currentsExpand
Null orbifolds in AdS, Time Dependence and Holography
We study M/D-branes in a null-brane background. By taking a near horizon limit, one is left with cosmological models in the corresponding Poincarpatches. To deal with their usual horizons, we eitherExpand
Twisting S-branes
Smooth time dependent supergravity solutions corresponding to analytic continuations of Kerr black holes are constructed and limits with a local de Sitter phase are found. These solutions areExpand


Fluxbranes in String Theory
A flux p-brane in D dimensions has (p+1)-dimensional Poincare invariance and a nonzero rank (D-p-1) field strength tangent to the transverse dimensions. We find a family of such solutions in stringExpand
Singular string solutions with nonsingular initial data
Abstract We consider a class of solutions to string theory obtained by identifying Minkowski space under a discrete subgroup of the Lorentz group. These lorentzian orbifolds have singularities whichExpand
Generalised supersymmetric fluxbranes
We classify generalised supersymmetric fluxbranes in type II string theory obtained as Kaluza-Klein reductions of the Minkowski space vacuum of eleven-dimensional supergravity. We obtain two familiesExpand
Geometry of the 2+1 black hole.
The geometry of the spinning black holes of standard Einstein theory in 2+1 dimensions, with a negative cosmological constant, and without couplings to matter, is analyzed in detail. It is shown thatExpand
Homogeneous fluxes, branes and a maximally supersymmetric solution of M-theory
We find M-theory solutions with homogeneous fluxes for which the spacetime is a lorentzian symmetric space. We show that generic solutions preserve sixteen supersymmetries and that there are twoExpand
Milne universe, tachyons, and quantum group
We analyze the spectrum of the bosonic and superstring on the orbifold of the space-time by a boost, leading to the cosmological singularity. We show that the modular invariance leads to the spectrumExpand
Supersymmetric Kaluza-Klein reductions of M2 and M5-branes
We classify and construct all the smooth Kaluza–Klein reductions to ten dimensions of the M2- and M5-brane configurations which preserve some of the supersymmetry. In this way we obtain a wealth ofExpand
Black hole in three-dimensional spacetime.
The standard Einstein-Maxwell equations in 2+1 spacetime dimensions, with a negative cosmological constant, admit a black hole solution that appears as a negative energy state separated by a mass gap from the continuous black hole spectrum. Expand
A New cosmological scenario in string theory
We consider new cosmological solutions with a collapsing, an intermediate and an expanding phase. The boundary between the expanding (collapsing) phase and the intermediate phase is seen by comovingExpand
A space-time orbifold: A toy model for a cosmological singularity
We explore bosonic strings and Type II superstrings in the simplest time dependent backgrounds, namely orbifolds of Minkowski space by time reversal and some spatial reflections. We show that thereExpand
