Collisions Between Ultracold Atoms and Cold Molecules in a Dual Electrostatic-Magnetic Trap
N. J. Fitch, L. P. Parazzoli, H. J. Lewandowski
Measurements of interactions between cold molecules and ultracold atoms can allow for a detailed understanding of fundamental collision processes. These measurements can be done us…
Two-Atom Rydberg Blockade using Direct 6S to nP Excitation
A. M. Hankin, Y. -Y. Jau, L. P. Parazzoli +4
We explore a single-photon approach to Rydberg state excitation and Rydberg blockade. Using detailed theoretical models, we show the feasibility of direct excitation, predict the e…
Observation of Free-Space Single-Atom Matterwave Interference
L. Paul Parazzoli, Aaron M. Hankin, Grant W. Biedermann
We observe matterwave interference of a single cesium atom in free fall. The interferometer is an absolute sensor of acceleration and we show that this technique is sensitive to fo…
Rotational-state purity of Stark-decelerated molecular beams
N. J. Fitch, D. A. Esteves, M. I. Fabrikant +4
Cold, velocity-controlled molecular beams consisting of a single quantum state promise to be a powerful tool for exploring molecular scattering interactions. In recent years, Stark…
Large Effects of Electric Fields on Atom-Molecule Collisions at Millikelvin Temperatures
L. P. Parazzoli, N. J. Fitch, P. S. Zuchowski +2
Controlling interactions between cold molecules using external fields can elucidate the role of quantum mechanics in molecular collisions. We create a new experimental platform in…
Experimental demonstration of classical Hamiltonian monodromy in the 1:1:2 resonant elastic pendulum
Noah J. Fitch, Carrie A. Weidner, L. Paul Parazzoli +2
The 1:1:2 resonant elastic pendulum is a simple classical system that displays the phenomenon known as Hamiltonian monodromy. With suitable initial conditions, the system oscillate…
