False-vacuum bubbles in sphaleron scattering
Manuel A. Martínez Sánchez, Christoph Adam, Danial Saadatmand
We investigate the collision dynamics of two bright sphalerons in a (1+1)-dimensional deformed scalar field theory with a symmetric potential possessing false vacua. Two one-…
Spinning boson stars in nonlinear sigma models and Universal Relations
Christoph Adam, Jorge Castelo Mourelle, Alberto García Martín-Caro +1
Boson stars are hypothetical compact objects derived from solutions of a self-gravitating complex scalar field. In this study, we extend the traditional models by generalizing the…
Universal Relations for Rotating Scalar and Vector Boson Stars
Christoph Adam, Jorge Castelo Mourelle, Etevaldo dos Santos Costa Filho +2
Bosonic stars represent a hypothetical exotic type of compact stellar objects that could be observed from the gravitational signal of coalescing binaries in current and future grav…
Galactic Halos and rotating bosonic dark matter
Jorge Castelo Mourelle, Christoph Adam
Rotating bosonic dark matter halos are considered as potential candidates for modeling dark matter in galactic halos. These bosonic dark matter halos can be viewed as a dilute and…
Rotating Fermion-Boson Stars
Jorge Castelo Mourelle, Christoph Adam, Juan Calderón Bustillo +1
Rotating fermion-boson stars are hypothetical celestial objects that consist of both fermionic and bosonic matter interacting exclusively through gravity. Bosonic fields are believ…
Moduli Space for Kink Collisions with Moving Center of Mass
Christoph Adam, Chris Halcrow, Katarzyna Oles +2
We apply the collective coordinate model framework to describe collisions of a kink and an antikink with nonzero total momentum, i.e., when the solitons possess different velocitie…
BPS soliton-impurity models and supersymmetry
C. Adam, Jose M. Queiruga, A. Wereszczynski
We find supersymmetric extensions of the half-BPS soliton-impurity models in (1+1) dimensions which preserve half of the supersymmetry. This is related to the fact…
Gauged BPS baby Skyrmions with quantised magnetic flux
C. Adam, A. Wereszczynski
A new type of gauged BPS baby Skyrme model is presented, where the derivative term is just the Schroers current (i.e., gauge invariant and conserved version of the topological curr…
The volume of a vortex and the Bradlow bound
C. Adam, J. M. Speight, A. Wereszczynski
We demonstrate that the geometric volume of a soliton coincides with the thermodynamical volume also for field theories with higher-dimensional vacuum manifolds (e.g., for gauged s…
Radial vibrations of BPS skyrmions
C. Adam, M. Haberichter, T. Romanczukiewicz +1
We study radial vibrations of spherically symmetric skyrmions in the BPS Skyrme model. Concretely, we numerically solve the linearised field equations for small fluctuations in a s…
The volume of a soliton
C. Adam, M. Haberichter, A. Wereszczynski
There exists, in general, no unique definition of the size (volume, area, etc., depending on dimension) of a soliton. Here we demonstrate that the geometric volume (area etc.) of a…
Topological energy bounds in generalized Skyrme models
C. Adam, A. Wereszczynski
The Skyrme model has a natural generalization amenable to a standard hamiltonian treatment, consisting of the standard sigma model and the Skyrme terms, a potential, and a certain…
Supersymmetric extensions of K field theories
C. Adam, J. M. Queiruga, J. Sanchez-Guillen +1
We review the recently developed supersymmetric extensions of field theories with non-standard kinetic terms (so-called K field theories) in two an three dimensions. Further, we st…
Twinlike models with identical linear fluctuation spectra
C. Adam, J. M. Queiruga
Recently, the possibility of so-called twinlike field theories has been demonstrated, that is, of different field theories which share the same topological defect solution with the…
An algebraic construction of twin-like models
C. Adam, J. M. Queiruga
If the generalized dynamics of K field theories (i.e., field theories with a non-standard kinetic term) is taken into account, then the possibility of so-called twin-like models op…
