Quantum test of the Universality of Free Fall using rubidium and potassium
H. Albers, A. Herbst, L. L. Richardson +11
We report on an improved test of the Universality of Free Fall using a rubidium-potassium dual-species matter wave interferometer. We describe our apparatus and detail challenges a…
Ground Tests of Einstein's Equivalence Principle: From Lab-based to 10-m Atomic Fountains
D. Schlippert, H. Albers, L. L. Richardson +10
To date, no framework combining quantum field theory and general relativity and hence unifying all four fundamental interactions, exists. Violations of the Einstein's equivalence p…
Quantum interference-enhanced deep sub-Doppler cooling of 39 K atoms in gray molasses
Dipankar Nath, R Kollengode Easwaran, G. Rajalakshmi +1
We report enhanced sub-Doppler cooling of the bosonic atoms of K facilitated by formation of dark states tuned for the Raman resonance in the configuration near the D1 t…
Accelerated Thermalisation of 39K atoms in a Magnetic Trap with Superimposed Optical Potential
Dipankar Nath, R Kollengode Easwaran, G. Rajalakshmi +1
We report the rapid accelerated thermalisation of Potassium 39 K atoms loaded in a magnetic trap, in the presence of a single dipole trap beam. More than an order of magnitude redu…
