2012-02-23, Dear Delia, ulsnes I am wrong, you have had given a seminar at Harvard about your well-known measure, too, didn't you? Do I remember that you were born in South Africa? You must have been hot as well, but the PC pressures and the evolution in time has transformed my memory into the word funny which is probably my mistake, sorry. By the way, I just looked at your arts, and especially the paintings of the bright men are very cool.Concering this tunneling, what you're saying about the actual dynamics seems to be a widely believed story, ulsnes I am misunderstanding some points, while the guessed consequences of the tunneling for the measures on the landscape will never be accepted. But I am still somewhat puzzled by your remarks about the localization of the domain walls in the extra dimensions. If a membrane is localized in the compact dimensions, its codimension is higher than one and it cannot really be a domain wall, can it?This issue doesn't seem to arise in the effective 4D description where the domain walls are always of codimension one and which should be OK as long as the instanton is much larger than the size of the compact manifold, shouldn't it?It's clear that there can be p-form fluxes with different p's, and they should correspondingly have different dimensionalities of the separating domain walls, too (depending on the number of compact dimensions extended within the relevant branes). But because the fluxes are spread over the compact manifold, I was expecting that the relevant branes would also be spread, and whether or not two of them can collide could be calculated from the 4D effective field theory, anyway.The lowest-dimensional analogy is Schwinger pair production which can occur anywhere in the electromagnetic field.Is this whole intuition wrong? I can imagine it is: the instantons and especially the branes that they create seem to be much more nonuniform or localized in the extra dimensions than the peaceful configurations at low energies, and even than the instantons themselves. If the relevant membranes' codimension is higher than one and the 4D effective QFT breaks down, the different bubbles really overlap with each other. Similar issues are really important for the long-term dynamics in the eternal inflation or whatever replaces it much like possible topological decay of the hidden manifolds into two, and similar qualitatively modifications of the naive picture.
