“PT Symmetry and the Taming of Instabilities”

Theoretical advances in PT symmetry have led to beautiful experimental results in optics, lasers, superconducting wires, atomic diffusion, NMR, microwave cavities, and electronic and mechanical simulations. Experiments on BECs are being planned and new PT-symmetric synthetic metamaterials are being developed. At an abstract level, PT-symmetric classical and quantum mechanics are complex generalizations of conventional classical and quantum mechanics. The advantage of extending physics into the complex domain is that theories that are unstable and physically unacceptable from the narrow perspective of real analysis may become stable and physically viable in the complex domain. This is because the conventional way to determine instability is based on energy inequalities; a theory is thought to be unstable if the potential is unbounded below..

Refreshments at 3:30 p.m. in Gant Complex, Physics, Rm. P-103.
