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 ...

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
