Please join us tomorrow, August 10th , at 11:00 AM in BRK 1001 for the seminar: Professor Debabrata Goswami, Indian Institute of Technology, Kanpur Host: Prof. Zubin Jacob On using "Shaped" light for understanding molecular length scale events of biological importance Abstract: Understanding molecular length-scale light-matter interactions through superresolution microscopy is of immense interest in modern biology. In this regard, shaping lasers is of utmost importance to provide the maximum spatial resolution at nanometer scales and temporal control and interactions. This presentation will discuss concepts relating to shaping lasers for their specific applications pedagogically. Based on our recent research, we will focus on measurement and confinement at molecular scale resolutions. This is drawn from our recent indigenous research of femtosecond optical tweezers and the superresolution microscopic studies performed at the minimum photon flux instrument, commercially known as MINFLUX. In particular, the discussions will focus on the recent localization studies with both these instruments, though they encompass significantly distinct ranges of light-matter interactions. Thank you, Pronoy Das Graduate Research Assistant, Prof. Jacob's research group
