Most General Spherically Symmetric M2-branes and Type IIB Strings
نویسنده
چکیده
We obtain the most general spherically symmetric M2-branes and type IIB strings, with R 1,2 × SO(8) and R 1,1 × SO(8) isometries, respectively. We find that there are 12 different classes of M2-branes, and we study their curvature properties. In particular, we obtain new smooth M2-brane wormholes that connect two asymptotic regions: one is flat and the other can be either flat or AdS 4 × S 7. We find that these wormholes are traversable with certain timelike trajectories. We also obtain the most general Ricci-flat solutions in five dimensions with R 1,1 × SO(3) isometries.

Brane Resolution Through Transgression
Modifications to the singularity structure of D3-branes that result from turning on a flux for the R-R and NS-NS 3-forms (fractional D3-branes) provide important gravity duals of four-dimensional N = 1 super-Yang-Mills theories. We construct generalisations of these modified p-brane solutions in a variety of other cases, including heterotic 5-branes, dyonic strings, M2-branes, D2-branes, D4-bra...
متن کاملGeneralized Hot Enhançons
We review what has been learnt and what remains unknown about the physics of hot enhançons following studies in supergravity. We recall a rather general family of static, spherically symmetric, non-extremal enhançon solutions describing D4 branes wrapped on K3 and discuss physical aspects of the solutions. We embed these solutions in the six dimensional supergravity describing type IIA strings ...
متن کاملHawking radiation of black p-branes via gauge and gravitational anomalies
We investigate the Hawking radiation of black p-branes in superstring theories through the method of anomaly cancelation proposed by Robinson andWilczec et al. The metrics of black p-branes are spherically symmetric, but not the Schwarzschild type generally. We find that in order to make the method of Robinson and Wilczec et al. effective for the calculation of Hawking fluxes for general non-Sc...
متن کاملOn the correspondence between D-branes and stationary supergravity solutions of type II Calabi-Yau compactifications.∗
In this talk, I review how four dimensional stationary supergravity solutions that are more general than spherically symmetric black holes emerge naturally in the low energy description of BPS states in type II Calabi-Yau compactifications. An explicit construction of multicenter solutions using single center attractor flows as building blocks is presented, and some interesting properties of th...
متن کاملSolitons on the Supermembrane
Energy bounds are derived for planar and compactified M2-branes in a hyper-Kähler background. These bounds are saturated, respectively, by lump and Q-kink solitons, which are shown to preserve half the worldvolume supersymmetry. The Q-kinks have a dual IIB interpretation as strings that migrate between fivebranes.
