“…Turning on the gauge fields, we have (2.36) Since now the worldvolume is the Euclidean 3 dimensional space, the gauge field strength was arranged into a magnetic field. As mentioned before, the symmetry ansatz adopted here 5 Although this funnel looks similar to what has been investigated in [6,7] which is called "spherical bulge", the crucial difference from ours is the dimensionality and the branes considered. In those papers, the decay of a fundamental string into a toroidal D2-brane with gauge flux was considered.…”

“…It is well known that D-branes and strings can decay via the tunnel effect in the background of the constant R-R field strength [5,6,7]. Along similar argument, one can find that the Myers' dielectric brane can decay via the tunnel effect.…”

“…) This was explicitly constructed in [12,13], and called sphaleron solutions. 7 These sphalerons were solutions in the Born-InfeldHiggs system on a single D-brane. The scalar field configuration of their solution shows a shape of a volcano, a "half" of the throat attached to the body of the flat D-brane.…”

Using D-brane effective field theories, we study dynamical decay of unstable brane systems : (i) a parallel brane-antibrane pair with separation l and (ii) a dielectric brane. In particular we give explicitly the decay width of these unstable systems, and describe how the decay proceeds after the tunnel effect. The decay (i) is analysed by the use of a tachyon effective action on the Dp-Dp. A pair annihilation starts by nucleation of a bubble of a tachyon domain wall which represents a throat connecting these branes, and the tunneling decay width Γ is found to be proportional to ∼ exp(−l p+1 T Dp ). We study also the decay leaving topological defects corresponding to lower-dimensional branes, which may be relevant for recent inflationary braneworld scenario. As for the decay (ii), first we observe that Dp-branes generically "curl up" in a nontrivial RR field strength. Using this viewpoint, we compute the decay width of the dielectric D2-branes by constructing relevant Euclidean bounce solutions in the shape of a funnel. We also give new solutions in doughnut shape which are involved with nucleation of dielectric branes from nothing.

“…We now estimate the decay rate of the false vacuum, basically along the lines of [47][48][49][50]. The transition proceeds via a domain wall D5-brane wrapping over the A 1 , A 2 and C cycles at the same point of our spacetime.…”

We consider a decay of a false vacuum in flux compactifications of type IIB string theory and study a catalytic effect for a phase transition induced by a new type of impurities. We concentrate on the large N dual of a D5-brane/anti-D5-brane system which has a rich vacuum structure. We show that D3-branes wrapping the 3-cycles can form a baryon bound state with a monopole. We find that these baryon-like objects can make the lifetime of the metastable vacuum shorter.

“…We consider here the cylindrical D2-brane with magnetic field in a purely timedependent case and demonstrate an analogy with the static, purely electric case [2,3]. This permits the consideration of quantum classical transitions in the magnetic case to be taken over from the electric case.…”

D2-branes with magnetic flux in the presence of RR fields

D2-branes are studied in the context of Born-Infeld theory as a source of the 3-form RR gauge potential. Considering the static case with only a radial magnetic field it is shown that a locally stable hemispherical deformation of the brane exists which minimises the energy locally. Since the D2-brane carries also the charge of D0-branes, and the RR spacetime potential is unbounded from below, these can tunnel to condense on the D2-brane. The corresponding instanton-like configuration and the tunneling rate are derived and discussed.
