Self-trapped quantum balls in binary Bose-Einstein condensates
(2019-02-13)
We study the formation of a stable self-trapped spherical quantum ball in a binary Bose-Einstein condensate (BEC) with two-body inter-species attraction and intra-species repulsion employing the beyond-mean-field Lee-Huang-Yang ...
Binary-disk interaction. ii. Gap-opening criteria for unequal-mass binaries
(The American Astronomical Society, 2014)
We study the interaction of an unequal-mass binary with an isothermal circumbinary disk, motivated by the
theoretical and observational evidence that after a major merger of gas-rich galaxies, a massive gaseous disk with
a ...

CE 315: a new interacting double-degenerate binary star
(UNIV CHICAGO PRESS, 2001-05-10)
We present spectroscopic observations of object CE 315 revealing a blue continuum with strong emission lines. Most of the detected lines are identified with He I or He II in emission, with a handful of faint lines of ...
Limitation of the Lee–Huang–Yang interaction in forming a self-bound state in Bose–Einstein condensates
(2019-10-01)
The perturbative Lee–Huang–Yang (LHY) interaction proportional to n3∕2, where n is the density, creates an infinitely repulsive potential at the center of a Bose–Einstein condensate (BEC) with net attraction, which stops ...
