Cosmological simulations of self-interacting Bose-Einstein condensate dark matter
S. T. H. Hartman, H. A. Winther, D. F. Mota
Fully 3D cosmological simulations of scalar field dark matter with self-interactions, also known as Bose-Einstein condensate dark matter, are performed using a set of effective hyd…
Constraints on self-interacting Bose-Einstein condensate dark matter using large-scale observables
S. T. H. Hartman, H. A. Winther, D. F. Mota
Constraints on the cosmic history of self-interacting Bose-Einstein condensed (SIBEC) dark matter (DM) are obtained using the cosmic microwave background (CMB), baryonic acoustic o…
Dynamical friction in Bose-Einstein condensed self-interacting dark matter at finite temperatures, and the Fornax dwarf spheroidal
S. T. H. Hartman, H. A. Winther, D. F. Mota
The aim of the present work is to better understand the gravitational drag forces, i.e. dynamical friction, acting on massive objects moving through a self-interacting Bose-Einstei…
Collapse of spherical overdensities in superfluid models of dark matter
S. T. H. Hartman, H. A. Winther, D. F. Mota
We intend to understand cosmological structure formation within the framework of superfluid models of dark matter with finite temperatures. Of particular interest is the evolution…
Superfluid Drag in Multicomponent Bose-Einstein Condensates on a Square Optical Lattice
Stian Hartman, Eirik Erlandsen, Asle Sudbø
The superfluid drag-coefficient of a weakly interacting three-component Bose-Einstein condensate is computed deep into the superfluid phase, starting from a Bose-Hubbard model with…
