Electrostatic quadrupole lens for focusing a cryogenic $^{205}$TlF molecular beam

Pengyu Zhou, Olivier Grasdijk, David DeMille, Jakob Kastelic et autres

Precision measurements with molecules require molecular beams with high flux and narrow divergence. Here we present the design, implementation, and characterization of an electrostatic quadrupole lens (EQL) for focusing a cryogenic beam of $^{205}$TlF molecules. The EQL consists of four electrodes operated …

Non-destructive cavity readout of molecules for precision measurements

Alejandro Salas-Estrada, Silviu‐Marian Udrescu, Geoffrey Zheng, Qian Wang et autres

We propose a non-destructive method to measure the population of molecules in a selected rotational-hyperfine state by coupling them to a high-finesse optical cavity. In contrast to traditional techniques, our approach enables fast (less than 1 ms) repeated measurements with reduced heating …

Cryogenic buffer gas beam source with in situ ablation target replacement

Zhen Han, Zack Lasner, Collin Diver, Peiran Hu et autres

The design and performance of a cryogenic buffer gas beam source with a load-lock system is presented. The third generation of advanced cold molecule electric dipole moment search (ACME III) uses this source to produce a beam of cold, slow thorium monoxide …

Non-Equilibrium Dynamics of Many-Body Quantum Systems: Fundamentals and New Frontiers

Yale Univ., New Haven, CT (United States), David DeMille, USDOE Office of Science (SC), Karyn LeHur

Rapid progress in nanotechnology and naofabrication techniques has ushered in a new era of quantum transport experiments. This has in turn heightened the interest in theoretical understanding of nonequilibrium dynamics of strongly correlated quantum systems. This project has advanced the frontiers of …
