Experimental observation of the tilting mode of an array of vortices in a dilute Bose-Einstein condensate.
We have measured the precession frequency of a vortex lattice in a Bose-Einstein condensate of Rb87 atoms. The observed mode corresponds to a collective motion in which all the vortices in the array are tilted by a small angle with respect to the z axis (the symmetry axis of the trapping potential)...
