A search for varying fundamental constants using Hz-level frequency measurements of cold CH molecules
S. Truppe, R. J. Hendricks, S. K. Tokunaga +5
Many modern theories predict that the fundamental constants depend on time, position, or the local density of matter. We develop a spectroscopic method for pulsed beams of cold mol…
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…
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…
High-energy-resolution molecular beams for cold collision studies
L. P. Parazzoli, N. Fitch, D. S. Lobser +1
Stark deceleration allows for precise control over the velocity of a pulsed molecular beam and, by the nature of its limited phase-space acceptance, reduces the energy width of the…
