[OMC11-06] Levitation dynamics of mesoscopic absorbing particles in a 3D photophoretic trap

*Anita Pahi1, Ayan Banerjee1 (1. IISER KOLKATA)

Our study shows interesting dynamics of mesoscopic particles in a photophoretic trap formed by a Gaussian beam. Trapped particles rotate with their rotation frequency being proportional to the trapping force. Some exhibit axial orbital rotation inversely linked to rotation frequency, revealing intricate equilibrium dynamics with particle-morphology dependence.
