Supersymmetry breaking and ghost Goldstino in modulated vacua
Sven Bjarke Gudnason, Muneto Nitta, Shin Sasaki +1
We discuss spontaneous supersymmetry (SUSY) breaking mechanisms by means of modulated vacua in four-dimensional supersymmetric field theories. The SUSY breaking due t…
Vibrational modes of Skyrmions
Sven Bjarke Gudnason, Chris Halcrow
We study the vibrational modes of Skyrmions with baryon numbers one through eight in the standard Skyrme model. The vibrational modes are found in the harmonic approximation around…
Temporally, Spatially or Light-like Modulated Vacua in Lorentz Invariant Theories
Sven Bjarke Gudnason, Muneto Nitta, Shin Sasaki +1
We study the vacuum structure of a class of Lorentz invariant field theories where the vacuum expectation values are not constant but are (phase) modulated. The vacua are classifie…
Baryonic handles: Skyrmions as open vortex strings on a domain wall
Sven Bjarke Gudnason, Muneto Nitta
We consider the BEC-Skyrme model which is based on a Skyrme-type model with a potential motivated by Bose-Einstein condensates (BECs) and, in particular, we study the Skyrmions in…
Exploring the generalized loosely bound Skyrme model
Sven Bjarke Gudnason
The Skyrme model is extended with a sextic derivative term - called the BPS-Skyrme term - and a repulsive potential term - called the loosely bound potential. A large part of the m…
Integer-Squared Laws for Global Vortices in the Born--Infeld Wave Equations
Zhifeng Gao, Sven Bjarke Gudnason, Yisong Yang
A series of quantization identities are established for static vortex solutions governed by the Born--Infeld type actions. These identities are of a universal nature which are indi…
Higher-order Skyrme hair of black holes
Sven Bjarke Gudnason, Muneto Nitta
Higher-order derivative terms are considered as replacement for the Skyrme term in an Einstein-Skyrme-like model in order to pinpoint which properties are necessary for a black hol…
Large- sigma model on a finite interval: general Dirichlet boundary conditions
Stefano Bolognesi, Sven Bjarke Gudnason, Kenichi Konishi +1
This is the third of the series of articles on the large- two-dimensional sigma model, defined on a finite space interval with Dirichlet boundary conditi…
The Skyrmion as a two-cluster system
Sven Bjarke Gudnason, Chris Halcrow
The classical Skyrmion can be approximated by a two-cluster system where a Skyrmion is attached to a core Skyrmion. We quantise this system, allowing the to…
