'Physics in the Complex Domain'

Friday, 26 January, 2018

Carl M. Bender, Ph.D., the Wilfred R. and Ann Lee Konneker Distinguished Professor of Physics at Washington University, will present at 4:10 p.m. on Friday, Jan. 26, in Room 202, Ritter Hall. Bender’s lecture is “Physics in the Complex Domain.”

Complex variable theory provides insight into the nature of physical theories. For example, it provides a simple and beautiful picture of quantization and it explains the underlying reason for the divergence of perturbation theory. By using complex-variable methods one can generalize conventional Hermitian quantum theories into the complex domain. The result is an exciting new class of parity-time-symmetric (PT-symmetric) theories whose remarkable physical properties are currently under intense study by theorists and experimentalists. Many theoretical predictions have been verified in recent laboratory experiments.

Tea will be served at 3:30 p.m. in the Ritter Hall lobby, with the talk to follow.
