Seminar by dr. Tijs Karman: "Field Control of Molecular Collisions" (Presentation)

Monday 19 October 2020Add to my calendar
from 11:00
Zoom (link see below)
dr. Tijs Karman (ITAMP, Haravrd, USA)


Ultracold polar molecules are a promising platform for upcoming quantum technologies such as quantum computing and quantum simulation. Currently, applications are limited by loss due to molecule-molecule collisions. I show that molecules can be shielded from this loss by inducing repulsive long-range interactions using microwaves[1]. Progress towards experimental realization of microwave shielding is presented. Microwave-dressing can also be used to tune interactions between molecules[2]. I will discuss these interactions and how these can be employed in applications such as quantum computing. In addition to using microwaves to control ultracold collisions, I will discuss the prospect of using electric fields to control collisions in a new generation of molecular beam experiments.
