Simultaneous measurement of mass and rotation of trapped absorbing particles in air
Sudipta K. Bera, Avinash Kumar, Souvik Sil +3
We trap absorbing micro-particles in air by photophoretic forces generated using a single loosely focused Gaussian trapping beam. We measure a component of the radial Brownian moti…

Temperature induced decay of persistent currents in a superfluid ultracold gas
Avinash Kumar, Stephen Eckel, Fred Jendrzejewski +1
We study how temperature affects the lifetime of a quantized, persistent current state in a toroidal Bose-Einstein condensate (BEC). When the temperature is increased, we find a de…
