[31/03/2021] Published: a general approach to state-dependent tweezer traps

"General approach to state-dependent optical-tweezer traps for polar molecules" shows how to trap a pair of molecules with a separation much smaller than the wavelength of the trapping light, greatly enhancing the dipole-dipole interaction between them. It is published today in Physical Review Research.

[29/03/2021] Welcome to Rhys Jenkins

Rhys joins the Ultracold EDM team

[01/03/2021] QSNET begins

Today we started a new project that aims to develop a clock based on vibrational transitions in ultracold molecules. We are part of the QSNET collaboration whose aim is to develop a network of clocks in the UK for testing fundamental physics. Our partners are at the University of Birmingham, University of Sussex and the National Physical Laboratory. The project is one of several within STFC's 'Quantum Technology for Fundamental Physics' programme.

[18/02/2021] Jongseok Lim is awarded an Ernest Rutherford Fellowship

Congratulations to Jongseok for being awarded an STFC Ernest Rutherford Fellowship. This is a brilliant achievement.

[08/02/2021] Chi Zhang is awarded a Marie Curie Fellowship

Congratulations to Chi who has been awarded a Marie Curie Fellowship to work on measuring the electron edm using ultracold molecules.

[29/01/2021] Published: characterisation of a single molecule in a photonic black box

Our paper "Coherent characterisation of a single molecule in a photonic black box" has been published in Nature Communications. We develop the theory of an emitter coupled to a photonic device, and then characterise the waveguide coupling of a single molecule placed inside a gap cut into the waveguide.

[09/12/2020] Published: how ultracold molecules can be used to measure the edm

Want to know how ultracold molecules can be used to measure the electron's electric dipole moment - our paper, published today in Quantum Science and Technology, shows how.

[07/12/2020] Published: enhancing dipole-dipole interactions in tweezer traps 

"Enhancing Dipolar Interactions between Molecules Using State-Dependent Optical Tweezer Traps" is published in Physical Review Letters. We show how the polarization structure of a tightly-focussed tweezer, together with the vector Stark shift, can be used to make state-dependent traps with controllable separation and how quantum gates can be implemented using this scheme.

[23/10/2020] Published: sub-Doppler spectroscopy at the single photon level

"Single-Photon-Level Sub-Doppler Pump-Probe Spectroscopy of Rubidium" is published today in Physical Review Applied.
