We use the resonant dipole-dipole interaction between Rydberg atoms and a periodic external microwave field to engineer XXZ spin Hamiltonians with tunable anisotropies. The atoms are placed in one-dimensional (1D) and two-dimensional (2D) arrays of o

Publikováno v: New Journal of Physics, Vol 19, Iss 11, p 113035 (2017)

We present the properties of a magneto-optical trap (MOT) of CaF molecules. We study the process of loading the MOT from a decelerated buffer-gas-cooled beam, and how best to slow this molecular beam in order to capture the most molecules. We determi

Quantum simulation using synthetic systems is a promising route to solve outstanding quantum many-body problems in regimes where other approaches, including numerical ones, fail1. Many platforms are being developed towards this goal, in particular ba

We report on improvements extending the capabilities of the atom-by-atom assembler described in [Barredo et al., Science 354, 1021 (2016)] that we use to create fully-loaded target arrays of more than 100 single atoms in optical tweezers, starting fr

Long Rotational Coherence Times of Molecules in a Magnetic Trap

Autor: M. R. Tarbutt, L. Caldwell, H. J. Williams, Noah Fitch, Jesus Aldegunde, Ben Sauer, Jeremy M. Hutson

Publikováno v: Physical Review Letters, 2020, Vol.124(6), pp.063001 [Peer Reviewed Journal]

Polar molecules in superpositions of rotational states exhibit long-range dipolar interactions, but maintaining their coherence in a trapped sample is a challenge. We present calculations that show many laser-coolable molecules have convenient rotati
