On DBI Textures with generalized Hopf fibration

Abstract

In this letter we show numerical existence of O(4) Dirac-Born-Infeld (DBI) Textures living in (N +1) dimensional spacetime. These defects are characterized by S N → S 3 mapping, generalizing the well-known Hopf fibration into π N (S 3 ), for all N > 3. The nonlinear nature of DBI kinetic term provides stability against size perturbation and thus renders the defects having natural scale. * Electronic address: ramadhan@teori.fisika.lipi.go.id arXiv:1205.6282v1 [hep-th]

More on Bogomol’nyi equations of three-dimensional generalized Maxwell-Higgs model using on-shell method

“…To have the Bogomol'nyi equations, the function f b must be of the form 10) where h b ≡ h b (r, φ). The Bogomol'nyi equations then are given by…”

“…This method may not always give the Bogomolnyi equations easily, especially when the Lagrangian contains noncanonical terms, as in the case of k-defects [4][5][6][7][8][9][10]. Recently, two of us proposed an alternative in obtaining the first-order equations by directly evaluating the Euler-Lagrange equations, later dubbed the on-shell method [1].…”

Chiral Dirac–Born–Infeld solitons with SDiff symmetry

“…For some generalizations see [10,11]. However, on the contrary to the standard skyrmions, little is known about DBI chiral solitons.…”

Some blackhole and compactification solutions of noncanonical global monopole in 4-dimensional spacetime

“…This model makes a stable theoretical model in N > 2 where N is the dimension [17]. It is used in many field in theoretical physics, such as global strings [18], cosmic strings [19], chiral theory [20], solitons [17], and textures [21].…”
