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…
Stabilisation of semilocal strings by dark scalar condensates
Péter Forgács, Árpád Lukács
Semilocal and electroweak strings are well-known to be unstable against unwinding by the condensation of the second Higgs component in their cores. A large class of current models…
Vortices and magnetic bags in Abelian models with extended scalar sectors and some of their applications
Péter Forgács, Árpád Lukács
A detailed study of vortices is presented in Ginzburg-Landau (or Abelian Higgs) models with two complex scalars (order parameters) assuming a general U(1)U(1) symmetric pot…
Vortices with scalar condensates in two-component Ginzburg-Landau systems
Peter Forgacs, Árpád Lukács
In a class of two-component Ginzburg-Landau models (TCGL) with a U(1)U(1) symmetric potential, vortices with a condensate at their core may have significantly lower energie…
"Half a proton" in the Bogomol'nyi-Prasad-Sommerfield Skyrme model
Árpád Lukács
The BPS Skyrme model is a model containing an -valued scalar field, in which a Bogomol'nyi-type inequality can be satisfied by soliton solutions. In this model, the energy d…
Time-Dependent BPS Skyrmions
Theodora Ioannidou, Arpad Lukacs
An extended version of the BPS Skyrme model that admits time-dependent solutions is discussed. Initially, by introducing a power law at the original potential term of the BPS Skyrm…
Non-Abelian Vortices with a Twist
Peter Forgacs, Arpad Lukacs, Fidel A. Schaposnik
Non-Abelian flux-tube (string) solutions carrying global currents are found in the bosonic sector of 4-dimensional N=2 super-symmetric gauge theories. The specific model considered…
Plane waves as tractor beams
Péter Forgács, Árpád Lukács, Tomasz Romańczukiewicz
It is shown that in a large class of systems plane waves can act as tractor beams: i.e., an incident plane wave can exert a pulling force on the scatterer. The underlying physical…
Instabilities of Twisted Strings
Peter Forgacs, Arpad Lukacs
A linear stability analysis of twisted flux-tubes (strings) in an SU(2) semilocal theory -- an Abelian-Higgs model with two charged scalar fields with a global SU(2) symmetry -- is…
