Fluctuating Fuzzy Funnels
It is well known that a D-string ending on a D3, D5 or D7 brane is described in terms of a non-commutative fuzzy funnel geometry. In this article, we give a numerical study of the fluctuations about this leading geometry. This allows us to investigate issues related to the stability and moduli space of these solutions. We comment on the comparison to the linearized fluctuations in supergravity.
متن کاملFive-brane Calibrations and Fuzzy Funnels
We present a generalisation of the Basu-Harvey equation that describes membranes ending on intersecting five-brane configurations corresponding to various calibrated geometries. email: [email protected] email: [email protected]
متن کاملElectrified Fuzzy Spheres and Funnels in Curved Backgrounds
We use the non-Abelian DBI action to study the dynamics of N coincident Dp-branes in an arbitrary curved background, with the presence of a homogenous world-volume electric field. The solutions are natural extensions of those without electric fields, and imply that the spheres will collapse toward zero size. We then go on to consider the D1−D3 intersection in a curved background and find variou...
متن کاملCombining Funnels
A new twist on an old tale.. . Abstract We enhance the well established software combining synchronization technique for shared memory multiprocessors to create combining funnels. Previous software combining methods used a statically assigned tree whose depth was logarithmic in the total number of processors in the system. The new method allows to dynamically build combining trees with depth lo...
متن کاملFunnels in Energy Landscapes
Local minima and the saddle points separating them in the energy landscape are known to dominate the dynamics of biopolymer folding. Here we introduce a notion of a “folding funnel” that is concisely defined in terms of energy minima and saddle points, while at the same time conforming to a notion of a “folding funnel” as it is discussed in the protein folding literature. PACS. 87.10.+e General...
