Fermions on Thick Branes in Background of Sine-Gordon Kinks
A class of thick branes in background of Sine-Gordon kinks had been constructed in hep-th/0407158 (Ref. [1]). In the background of the warped geometry and the kink, the localization problem of massive fermions on the branes had also been discussed, and discrete massive fermion states on the branes were obtained. In this paper, we reinvestigate the issue of localization of spin half fermions on ...
متن کاملBlack Holes on Thick Branes
The interplay between topological defects (branes) and black holes has been a subject of recent study, motivated in part by interest in brane-world scenarios. In this paper we analyze in detail the description of a black hole bound to a domain wall (a two-brane in four dimensions), for which an exact description in the limit of zero wall thickness has been given recently. We show how to smooth ...
متن کاملFermions on Thick Branes in the Background of Sine-Gordon Kinks
A class of thick branes in the background of sine-Gordon kinks with a scalar potential V (φ) = p(1 + cos 2φ q ) had been constructed in hep-th/0407158 (Ref. [1]). In this paper, in the background of the warped geometry, we investigate the issue of localization of spin half fermions on these branes in the presence of two types of scalar-fermion couplings: ηΨ̄φΨ and ηΨ̄ sinφΨ. By presenting the mas...
متن کاملThick branes and 4D gravity
The induced 4d gravity on a brane world is analyzed. The case of a thick brane is considered and the unexpected appearance of a new threshold scale, much larger than the thickness scale is found. In cases of phenomenological interest, this new length scale turns out to be in the submillimeter range. The effect of R corrections, both in the bulk and on the brane, is also studied. It is shown tha...
متن کاملq-Deformed Oscillators and D-branes on Conifold
We study the q-deformed oscillator algebra acting on the wavefunctions of non-compact D-branes in the topological string on conifold. We find that the mirror B-model curve of conifold appears from the commutation relation of the q-deformed oscillators.
