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


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

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.

the FET Work Programme 2016-2017 - FETFLAG-02-2017: Coordination and Support Action for Quantum Technologies


The 2016-2017 FET programme has been updated in order to include a new call for a coordination action for Quantum Technologies

the FET Work Programme 2016-2017 has been adopted yesterday and is now available here: http://ec.europa.eu/research/participants/data/ref/h2020/wp/2016_2017/main/h2020-wp1617-fet_en.pdf

As you will see on page 36, there is an additional call FETFLAG-02-2017: Coordination and Support Action for Quantum Technologies

The call will open on 23 May 2017 and close on 26 September 2017.
