Hair on non-extremal D1-D5 bound states [PDF]

Journal of High Energy Physics, 2016
A bstractWe consider a truncation of type IIB supergravity on four-torus where in addition to the Ramond-Ramond 2-form field, the Ramond-Ramond axion (w) and the NS-NS 2-form field (B) are also retained.

Nondimensional Characterization of the Operational Envelope of a Wet Friction Clutch

Computation, 2020
In recent years, multidisc wet friction clutches are used in demanding powertrains of automatic and dual clutch transmissions targeting high efficiency and smoothness during gearshift.

The post-collapse equilibrium structure of cosmological haloes in a low-density universe [PDF]

, 2001
An analytical model is presented for the postcollapse equilibrium structure of virialized objects which condense out of a low-density cosmological background universe, either matter-dominated or flat with a cosmological constant.

Driven neutron star collapse: Type I critical phenomena and the initial black hole mass distribution [PDF]

, 2015
We study the general relativistic collapse of neutron star (NS) models in spherical symmetry. Our initially stable models are driven to collapse by the addition of one of two things: an initially in-going velocity profile, or a shell of minimally coupled,

AdS_3 x S^3 (Un)twisted and Squashed, and an O(2,2;Z) Multiplet of Dyonic Strings [PDF]

, 1998
We consider type IIB configurations carrying both NS-NS and R-R electric and magnetic 3-form charges, and whose near horizon geometry contains AdS_3 x S^3. Noting that S^3 is a U(1) bundle over CP^1 \sim S^2, we construct the dual type IIA configurations

Effective actions and N=1 vacuum conditions from SU(3) x SU(3) compactifications [PDF]

, 2007
We consider compactifications of type II string theory on general SU(3) x SU(3) structure backgrounds allowing for a very large set of fluxes, possibly nongeometric ones. We study the effective 4d low energy theory which is a gauged N=2 supergravity, and

Cosmological Solutions in String Theories [PDF]

, 1996
We obtain a large class of cosmological solutions in the toroidally-compactified low energy limits of string theories in $D$ dimensions. We consider solutions where a $p$-dimensional subset of the spatial coordinates, parameterising a flat space, a ...

Brane-world Kaluza-Klein reductions and Branes on the Brane [PDF]

, 2000
We present a systematic study of a new type of consistent ``Brane-world Kaluza-Klein Reduction,'' which describe fully non-linear deformations of co-dimension one objects that arise as solutions of a large class of gauged supergravity theories in diverse

The alpha-prime stretched horizon in the Heterotic string [PDF]

, 2006
The linear alpha-prime corrections and the field redefinition ambiguities are studied for half-BPS singular backgrounds representing a wrapped fundamental string.

Classification of p-branes, NUTs, Waves and Intersections [PDF]

, 1997
We give a full classification of the multi-charge supersymmetric $p$-brane solutions in the massless and massive maximal supergravities in dimensions $D\ge2$ obtained from the toroidal reduction of eleven-dimensional supergravity.
