4-th year PhD student attestation: Transfer of linear and angular momentum to subwavelength scatterers in opto- and acoustomechanics

This is a pre-defence of a theoretical work. Thesis is devoted to the mechanical action of light and acoustic fields, in particular to the transver of linear and angular momenta (AM). Variuos systems are considered: optical binding next to a nanofiber, orbiting motion around nanofiber, analyses of the AM of eigen modes of a sphere, and torque generated via second harmonic generation.
