| 11:00 - 12:00 Wednesday Weekly Seminar-google meet What are the two major themes of theoretical high energy physics these days? School PARTICLES AND ACCELERATORS Abstract: In this talk, I will briefly describe what are the major hot topics in theoretical high energy physics these days, what questions are being answered, and what motivations are being pursued. Indico: https://indico.particles.ipm.ir/indico/event/423 https://meet.google.com/srb-pwrc-jwz ... 13:30 - 15:00 Weekly Seminar (Online) On Consistent Theories of Massive Spin-2 Fields https://www.skyroom.online/ch/soa/weekly-seminar School ASTRONOMY Abstract In this talk, I will review the recent results in Hamiltonian structure of Massive gravity and Bi gravity models in nonlinear level. Then, I will specifically focus on the Hamiltonian structure of three and four gravity. Finally, I present a perfect Hamiltonian structure for a multi-gravity model in the full phase space with deriving gauge generator. ... 14:00 - 15:00 Weekly Seminar Speckle Tweezers for Controlling Collective Motion of Micro-objects School NANO SCIENCES Speckle tweezers (ST) by incorporating randomly distributed light fields can be used to control micro-particles to perform manipulation tasks such as guiding and sorting. Indeed, compared to periodic potentials, ST represents a wider possibility to be operated for such tasks. In this talk, we will explore the usefulness of ST in collective motion control of an ensemble of micro-particles of high and low index with respect to the surrounding as well as nano-particle loaded low index vesicles. The potential applications toward controlling collective transportation of drug micro-containers and directed motion of a mixture of micro-objects will b ... |
