Resonances and their collapse in moving binaries

When two coupled point masses move in a periodic potential the energy of their collective motion may get transferred, via resonance, to the energy of their relative motion. Two pendula with torsional coupling is a prime example. I will describe the role of the symplectic group played in this effect, a connection with the finite-zone Lame potential and a certain universality in the resonant behavior.

Joint work with Jing Zhou.
