Abstract:
Recent developments in the experimental control and manipulation of atomic and molecular quantum states and high-precision spectral measurements through synchronization with atomic clocks have led to several proposals for testing the Standard Model using atoms and molecules. This talk will focus on small systems, for which the underlying equations can be solved to almost arbitrary precision, and comparison with the increasingly accurate experimental results gives us the opportunity to think about the equations themselves. I will speak about the development of theoretical and computational tools of molecular quantum theory beyond the Born-Oppenheimer and non-relativistic approximations, introduced in the molecular theory ca. 100 years ago. Going beyond the non-relativistic approximation turns out to be particularly challenging and requires the development of ideas about the application of relativistic quantum electrodynamics to bound systems. I will highlight our recent developments in bound-state quantum electrodynamics and connections with relativistic quantum chemistry.
