“Angular Momentum Conservation in Molecular Born-Oppenheimer Theory”
Research
-I have broad interests in atomic, molecular, nuclear, optical, and plasma physics, and in nonlinear dynamics. I am especially interested in mathematical aspects of basic problems in applied physics. Projects in the last ten years have included studies of periodic orbits in the semiclassical quantization of chaotic systems; topological aspects of semiclassical quantization; a normal form theory for Landau-Zener transitions, also known as mode conversion; entropy and phase space representations of optical fields; studies of diffraction in nonimaging optics; gauge fields in the separation of rotations and internal motions in few-body systems; and wavelets and wavelet-like bases for scattering theory in few-body systems. Several of these projects have led to dissertations for my students; the last two mentioned are current. The unifying themes of this work are Hamiltonian dynamics, short-wavelength asymptotics, the classical-quantum correspondence, geometrical and topological methods, and symmetry.
