Quantum-state engineering is of critical importance to the development of quantum technologies. One promising platform is thermal atomic vapours, because they offer long coherence times with reproducible and scalable hardware. However, the inability to address isolated atomic states in a controlled manner, due to multi-level degeneracy and motional broadening, is a major obstacle to their wider application.

Driven-dissipative many-body systems with mixed power-law interactions: Bistabilities and temperature-driven nonequilibrium phase transitions

Date: 
2016-07-14
Author(s): 

N. Sibalic, C. G. Wade, C. S. Adams, K. J. Weatherill and T. Pohl

PHYSICAL REVIEW A 94, 011401(R) (2016)

We investigate the nonequilibrium dynamics of a driven-dissipative spin ensemble with competing power-law interactions. We demonstrate that dynamical phase transitions as well as bistabilities can emerge for asymptotic van der Waals interactions, but critically rely on the presence of a slower decaying potential core.

Probing interactions of thermal Sr Rydberg atoms using simultaneous optical and ion detection

Date: 
2017-04-21
Author(s): 

Hanley, Ryan K and Bounds, Alistair D and Huillery, Paul and Keegan, Niamh C and Faoro, Riccardo and Bridge, Elizabeth M and Weatherill, Kevin J and Jones, Matthew P A

Reference: 

arXiv:1702.05039

We demonstrate a method for probing interaction effects in a thermal beam of strontium atoms using simultaneous measurements of Rydberg EIT and spontaneously created ions or electrons. We present a Doppler-averaged optical Bloch equation model that reproduces the optical signals and allows us to connect the optical coherences and the populations.
