Atomic Beam Spectroscopy of Thallium and Tests of Fundamental Physics

Professor Tiku Majumder

Williams College

High-precision spectroscopy in atoms, coupled with accurate, ab-initio wavefunction calculations, can provide important physical insights whose scope extends well beyond the realm of 'atoms'. Currently, precise experiments in atoms set important constraints on physics beyond the 'Standard Model' through parity nonconservation measurements, EDM measurements, tests of Lorentz and CPT-violating forces, etc. I will discuss recent high-precision diode-laser spectroscopy experiments at Williams aimed at testing and complementing current atomic structure calculations in thallium. Future plans include using our thallium atomic beam apparatus to test for possible long-range T-violating (but P-conserving) forces.
