چکیده
We discuss Bogomol'nyi equations for general gauge theories (depending on the two Maxwell invariants F µν F µν and˜F µν F µν) coupled to Higgs scalars. By analysing their supersymmetric extension, we explicitly show why the resulting BPS structure is insensitive to the particular form of the gauge Lagrangian: Maxwell, Born-Infeld or more complicated non-polynomial Lagrangians all satisfy the same Bogomol'nyi equations and bounds which are dictated by the underlying supersymmetry algebra.

We study N = 2 supersymmetric Born-Infeld-Higgs theory in 3 dimensions and derive Bogomol’nyi relations in its bosonic sector. A peculiar coupling between the Higgs and the gauge field (with dynamics determined by the Born-Infeld action) is forced by supersymmetry. The resulting equations coincide with those arising in the MaxwellHiggs model. Concerning Bogomol’nyi bounds for the vortex energy,...

Supersymmetric σ-models obtained by constraining linear supersymmetric field theories are ill defined. Well defined subsectors parametrising Kahler manifolds exist but are not believed to arise directly from constrained linear ones. A counterexample is offered using improved understanding of membranes in superstring theories leading to crucial central terms modifying the algebra of supercharge ...

We present some obvious physical requirements on gravitational avatars of non-linear elec-trodynamics and illustrate them with explicit determinantal Born–Infeld–Einstein models. A related procedure, using compensating Weyl scalars, permits us to formulate conformally invariant versions of these systems as well. Born–Infeld (BI) electrodynamics [1] has earned its longevity through its elegant, ...

The perspectives of numerical simulations in supersymmetric quantum field theories with vector-like gauge symmetries are discussed. A numerical simulation algorithm for SU(2) gauge theory with gluinos is studied and the first results on the glueball-gluinoball spectrum are presented.
