“Superoscillations, the Talbot Carpet, and Gauss Sums”

The Department of Physics invites all members of the campus community to attend the event, “Superoscillations, the Talbot Carpet, and Gauss Sums,” Thursday, March 24, at 4 p.m., in Rockefeller Building (Room 301) or via Zoom.

Chapman University’s 13th president, Daniele Struppa, will give a colloquium on superoscillations, a phenomenon that appears in different areas, including optics and weak quantum measurements. 

Struppa’s talk will examine the evolution of the Dirac comb (infinite sum of deltas) to show how to recover, optically, the generalized quadratic Gauss sums, and the theory of superoscillations to show how such Gauss sums can be asymptotically recovered from the values of the spectrum of any sufficiently regular function with compact support.

Refreshments will be provided after the colloquium.
