Einstein's summary of orbital and boson stars
WebBoson stars are often described as macroscopic Bose-Einstein condensates. By accommodating large numbers of bosons in the same quantum state, they materialize macroscopically the intangible probability density cloud of a single particle in the quantum world. We take this interpretation of boson stars one step further. WebSep 11, 2024 · Abstract. In this paper, we study circular orbits of spinning test particles in the background of a rotating boson star. Using the pole-dipole approximation and …

WebJun 19, 2007 · Due to the lack of Lorentz covariance, such travelling solitary waves cannot be obtained by applying a Lorentz boost to a solitary wave at rest (with v = 0). To overcome this difficulty, we introduce and study an appropriate variational problem that yields the functions \varphi_v \in {\bf H}^ {1/2} ( {\mathbb {R}}^3) as minimizers, which we ...

WebSep 23, 2013 · Compact bosonic field configurations, or boson stars, are promising dark matter candidates which have been invoked as an alternative description for the supermassive compact objects in active galactic nuclei. Boson stars can be comparable in size and mass to supermassive objects, and they might be hard to distinguish by … WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract Bound states of complex scalar fields (boson stars) have long been proposed as possible candidates for the dark matter in the universe. Considerable work has already been done to study various aspects of boson stars.
WebMay 8, 2012 · They can thus be considered a Bose-Einstein condensate (BEC), although boson stars can also exist in an excited state as well. Indeed, applying the uncertainty principle to a boson star by assuming it to be a macroscopic quantum state results in an excellent estimate for the maximum mass of a BS.
