Thomas Langin, Yale: “Ultracold Molecules: A New Tool for Studying Strongly Interacting Quantum Systems”

Thomas Langin from Yale University will be speaking on Bose-Einstein Condensates (BECs).

BECs, in which the material is cold and dense enough that the wavefunctions of the particles overlap (e.g., when the DeBroglie wavelength (λ∝1/√T) equals the interparticle spacing (a∝n^(- 1/3))), are typically created by cooling N≥1000 atoms to T≤100 nK. These systems have many interesting properties, such as superfluidity, easily tunable interactions and phase coherence. However, in most atoms, interactions are limited to short-range van der Waals interactions.

At Yale, we are attempting to create BECs of SrF, a polar molecule which has strong, tunable, long-range dipole-dipole interactions. Molecules also have many easily accessible long-lived rotational states, which make them attractive for quantum information studies. In this talk, I will discuss the techniques we have implemented thus far to cool thousands of SrF molecules to T∼10μK. I will conclude by discussing our progress toward reaching lower temperatures and achieving a BEC of SrF.

RBG: Movie Night Celebrating Ruth Bader Ginsburg

At the age of 85, U.S. Supreme Court Justice Ruth Bader Ginsburg has developed a lengthy legal legacy while becoming an unexpected pop culture icon. But the unique personal journey of her rise to the nation's highest court has been largely unknown, even to some of her biggest fans – until now. RBG is a revelatory documentary exploring Ginsburg's exceptional life and career from Betsy West and Julie Cohen, and co-produced by Storyville Films and CNN Films.

Snacks will be provided at this indoor documentary showing, held in anticipation of Justice Ginsburg's visit to campus on October 3.

“Do Things to Images”: An Exhibition by Odette England

Do Things to Images presents for the first time a selection of photographs from 2014 to 2019 by the artist Odette England. It includes images from her newest series Love Notes.

England’s parents’ former dairy farm, and the archive of snapshots her family made there, serve as raw material for England’s practice. Many of her photographs are unique pieces. By mixing preciousness with low-fi, unrepeatable processes, England highlights the infidelity of memory.

This exhibition includes prints from negatives that England buried and then dug up, and hand-torn paper prints. It features pages ripped from family photo albums, and vintage snapshots that have been hole-punched, among other works. Her need to cut, crop, sand, fold and otherwise manipulate photographs is in contrast to the French meaning of her name, Odette, “Lover of Home.”

Join Odette England for a lecture and the opening of her exhibition on Thursday, Sept. 19, at 4:30 p.m. in Pruyne Lecture Hall, 115 Fayerweather.
