Dynamical Boson Stars [PDF]

Living Reviews in Relativity, 2012
AbstractThe idea of stable, localized bundles of energy has strong appeal as a model for particles. In the 1950s, John Wheeler envisioned such bundles as smooth configurations of electromagnetic energy that he called geons, but none were found. Instead, particle-like solutions were found in the late 1960s with the addition of a scalar field, and these ...

Quasi-bosons approximate bosons

Reports on Mathematical Physics, 1997
The authors consider the Kac bosons in an abstract version of the wedge algebra. For every \(n\) they cut the shift operator of a fixed orthonormal basis to make it act in a finite-dimensional subspace \({\mathcal H}_n\). This leads to a new set of commutation rules which are then used to define the quasi-bosons now existing in a finite-dimensional ...

When is a boson not a boson? [PDF]

Physics World, 1995
I have read with interest recent articles about quantum gases in Physics World (July pp37–41, August p2l). I would, however, like to issue a word of warning before the Orwellian chant "even number of fermions bosons, odd number of fermions fermion" becomes too ingrained in the physics folklore.

Boson Stars and Boson Shells

Few-Body Systems, 2018
In this work we present a broad formalism for a study of the models of black holes, boson stars, boson shells and wormholes. The studies of boson stars and boson shells in a theory involving Scalar field, U(1) gauge field and a shelf interacting scalar potential coupled to gravity in the presence of a cosmological constant

EWK Bosons and the Higgs Boson

2016
As discussed, in Chap. 2, the Higgs boson plays an important role in the process of electroweak symmetry breaking. Correspondingly, the couplings of the electroweak boson to the Higgs boson are noticeably different in structure and strength compared to the Yukawa couplings responsible for the fermion masses.

Inconsistency of Cubic Boson-Boson Interactions

Physical Review, 1960
It is shown that there does not exist a ground state for a system of spin zero bose fields coupled only by local interactions involving three powers of the fields. Thus these interactions alone are not suitable for a model of interacting fields.
