Charge screening in the Abelian Higgs model
Péter Forgács, Árpád Lukács
In the Abelian Higgs model electric (and magnetic) fields of external charges (and currents) are screened by the scalar field. In this contribution, complementing recent investigat…
On non-topological solitons in Abelian gauge theories coupled to U(1)U(1) symmetric scalar fields
Péter Forgács, Árpád Lukács
In a series of recent works Ishihara and Ogawa have investigated non-topological solitons (Q-balls) in a spontaneously broken Abelian gauge theory coupled to two complex scalar fie…
Electroweak strings with dark scalar condensates and their (in)stability
Péter Forgács, Árpád Lukács
The stability of "visible" electroweak-type cosmic strings is investigated in an extension of the Standard Model (SM) by a minimal dark sector, consisting of a U(1) gauge field, br…
Canonical quantization and black hole perturbations
Zoltan Perjes, Arpad Lukacs
We examine the possibility of a constraint-free quantization of linearized gravity, based on the Teukolsky equation for black hole perturbations. We exhibit a simple quadratic (but…
