Measuring the stability of fundamental constants with a network of clocks
G. Barontini, L. Blackburn, V. Boyer +41
The detection of variations of fundamental constants of the Standard Model would provide us with compelling evidence of new physics, and could lift the veil on the nature of dark m…
Collective strong coupling of cold potassium atoms in a ring cavity
Robert Culver, Andreas Lampis, Balázs Megyeri +5
We present experiments on ensemble cavity quantum electrodynamics with cold potassium atoms in a high-finesse ring cavity. Potassium-39 atoms are cooled in a two-dimensional magnet…
Observing Coherence Effects in an Overdamped Quantum System
Y. -H. Lien, G. Barontini, M. Scheucher +3
It is usually considered that the spectrum of an optical cavity coupled to an atomic medium does not exhibit a normal-mode splitting unless the system satisfies the strong coupling…
Looking for "avalanche-mechanism" loss at an atom-molecule Efimov resonance
Ming-Guang Hu, Ruth S. Bloom, Deborah S. Jin +1
The "avalanche mechanism" has been used to relate Efimov trimer states to certain enhanced atom loss features observed in ultracold atom gas experiments. These atom loss features a…
Polarization spectroscopy and magnetically-induced dichroism of the potassium D2 lines
K. Pahwa, L. Mudarikwa, J. Goldwin
We study modulation-free methods for producing sub-Doppler, dispersive line shapes for laser stabilization near the potassium D2 transitions at 767 nm. Polarization spectroscopy is…
