Emergent devil's staircase without particle-hole symmetry in Rydberg quantum gases with competing attractive and repulsive interactions (2015)
Journal Article

The devil's staircase is a fractal structure that characterizes the ground state of one-dimensional classical lattice gases with long-range repulsive convex interactions. Its plateaus mark regions of stability for specific filling fractions which are...

Coherence in a cold atom photon transistor (2015)
Journal Article

Recent experiments have realized an all-optical photon transistor using a cold atomic gas. This approach relies on electromagnetically induced transparency (EIT) in conjunction with the strong interaction among atoms excited to high-lying Rydberg sta...

Non-equilibrium universality in the dynamics of dissipative cold atomic gases (2015)
Journal Article

The theory of continuous phase transitions predicts the universal collective properties of a physical system near a critical point, which for instance manifest in characteristic power-law behaviours of physical observables. The well-established conce... Read More about Non-equilibrium universality in the dynamics of dissipative cold atomic gases.

Phase-imprinting of Bose-Einstein condensates with Rydberg impurities (2015)
Journal Article

We show how the phase profile of Bose-Einstein condensates can be engineered through its in- teraction with localized Rydberg excitations. The interaction is made controllable and long-range by off-resonantly coupling the condensate to another Rydber...

Spin correlations as a probe of quantum synchronization in trapped ion phonon-lasers (2015)
Journal Article

We investigate quantum synchronization theoretically in a system consisting of two cold ions in microtraps. The ions' motion is damped by a standing-wave laser whilst also being driven by a blue-detuned laser which results in self-oscillation. Workin...
