Compared to atoms, polar molecules have extremely large electric polarizability arising from the small energy spacing between rotational states. This property has up to now been largely unexploited for fundamental studies and is at the heart of most of our experiments. We use it both as a means of amplifying tiny symmetry-violating effects within the molecules and as a means for manipulating the external properties of the molecules.<\/p>\n\n\n\n<p>Click on the research titles to the left to more about each project or check out one of the videos below.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"David DeMille, Yale University\" width=\"1000\" height=\"750\" src=\"https:\/\/www.youtube.com\/embed\/xrekC84Ufjk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"ICAP 2014 - D.
