A Morphological-type dependence in the mu_0-log(h) plane of Spiral galaxy disks [PDF]

open access: yes, 2001
We present observational evidence for a galaxy `Type' dependence to the location of a spiral galaxy's disk parameters in the mu_0-log(h) (central disk surface-brightness - disk scale-length) plane.

Bright solitons in spin-orbit-coupled Bose-Einstein condensates [PDF]

open access: yesPhysical Review A 87, 013614 (2013), 2012
We study bright solitons in a Bose-Einstein condensate with a spin-orbit coupling that has been realized experimentally. Both stationary bright solitons and moving bright solitons are found. The stationary bright solitons are the ground states and possess well-defined spin-parity, a symmetry involving both spatial and spin degrees of freedom; these ...
