Zero-brane approach to quantization of biscalar field theory about topological kink-bell solution
نویسنده
چکیده
We study the properties of the topologically nontrivial doublet solution arisen in the biscalar theory with a fourth-power potential introducing an example of the spontaneous breaking of symmetry. We rule out the zero-brane (non-minimal point particle) action for this doublet as a particle with curvature. When quantizing it as the theory with higher derivatives, we calculate the quantum corrections to the mass of the doublet which could not be obtained by means of the perturbation theory. PACS number(s): 11.10.Lm, 11.15.Ex, 11.27.+d

So(32) Spinors of Type I and Other Solitons on Brane-antibrane Pair
We construct the SO(32) spinor state in weakly coupled type I string theory as a kink solution of the tachyon field on the D-string − anti-D-string pair and calculate its mass. We also give a description of this system in terms of an exact boundary conformal field theory and show that in this description this state can be regarded as a non-supersymmetric D0-brane in type I string theory. This c...
متن کاملZero-brane approach to quantization of multiscalar field theories and its application for fixed-gauge Jackiw-Teitelboim gravity about instanton-dilaton black hole solution
The effective zero-brane action approach is generalized for arbitrary multiscalar fields. As an example, by virtue of this method we derive the nonminimal particle action for the Jackiw-Teitelboim gravity at fixed gauge in the vicinity of the black hole solution as an instanton-dilaton doublet. When quantizing it as the theory with higher derivatives, it is shown that the appearing quantum equa...
متن کاملDirac-Born-Infeld Action on the Tachyon Kink and Vortex
The tachyon effective field theory describing the dynamics of a non-BPS D-brane in superstring theory has an infinitely thin but finite tension kink solution describing a codimension one BPS D-brane. We study the world-volume theory of massless modes on the kink, and show that the world volume action has precisely the Dirac-Born-Infeld (DBI) form without any higher derivative corrections. We ge...
متن کاملNoncommutative Tachyon Kinks as D(p− 1)-branes from Unstable Dp-brane
We study noncommutative (NC) field theory of a real NC tachyon and NC U(1) gauge field, describing the dynamics of an unstable Dp-brane. For every given set of diagonal component of open string metric G0, NC parameter θ0, and interpolating electric field Ê, we find all possible static NC kinks as exact solutions, in spite of complicated NC terms, which are classified by an array of NC kink-anti...
متن کاملRemarks on bell-shaped lumps: stability and fermionic modes
We consider non-topological, ”bell-shaped” localized and regular solutions available in some 1+1 dimensional scalar field theories. Several properties of such solutions are studied, namely their stability and the occurence of fermion bound states in the background of a kink and a kink-anti-kink solutions of the sine-Gordon model.
