# Charged compact boson stars and shells in the presence of a cosmological constant

@article{Kumar2016ChargedCB, title={Charged compact boson stars and shells in the presence of a cosmological constant}, author={Sanjeev Kumar and Usha Kulshreshtha and Daya Shankar Kulshreshtha}, journal={Physical Review D}, year={2016}, volume={94}, pages={125023} }

In this work we study the boson stars and boson shells in a theory involving massive complex scalar fields coupled to the U(1) gauge field and gravity in a conical potential in the presence of a cosmological constant ${\Lambda}$ which we treat as a free parameter taking positive and negative values and thereby allowing us to study the theory in the de Sitter and Anti de Sitter spaces respectively. Boson stars are found to come in two types, having either ball-like or shell-like charge density…

There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
