We are organising a Royal Society meeting on "Breakdown of ergodicity in quantum systems: from solids to synthetic matter"Ergodic systems lie at the heart of statistical physics since they reach thermal equilibrium and 'forget' their initial conditions, thereby allowing for coarse-grained classical descriptions. Recently, non-ergodic quantum many-…

We are currently advertising two PostDoc positions.We are currently advertising two Postdoc (PDRA) positions in our group. One position is in the context of our ERC project on Optical Quasicrystals while the other is associated with a new experiment.The deadline for applications is February 28th 2017.For details see:http://www.jobs.cam.ac.uk/job/12…

Our new ERC project on creating an optical Quasicrystal has started.Our new ERC project on creating an Optical Quasicrystal has started on January 1st. The main objective of this project is to extend the level of control achieved in optical lattices to 2D quasiperiodic potentials by realising an optical quasicrystal.Quasicrystals are a novel form o…

Our paper on exploring the geometric structure of energy bands using a strong force dynamics has been published in Science. Geometry and topology of electronic states in solids play a central role in a wide range of modern condensed-matter phenomena, ranging from the Quantum Hall effect over the peculiar physics of Graphene to Topological Insulator…

Our paper on the dimensional crossover of Many-body localization was published as an Editor's suggestion in PRL. In this work we could show that individual localized systems can-when coupled together-start to act as a bath for themselves and restore ergodic behavior.Many-Body Localization (MBL) represents a generic alternative to thermalization in…

Cavmag: News from the Cavendish Laboratory.Our Many-body group has been featured in the latest issue of Cavmag: News from the Cavendish Laboratory.

Our paper on the emergence of coherence far from equilibrium was published in PRL (PRL 115, 175301) and has an accompanying viewpoint in Physics.Long-range coherence is typically restricted to equilibrium situations at low temperatures. Here we have, in stark contrast, for the first time managed to observe the dynamic emergence of coherence in a sy…

We have observed a novel state of matter that, despite being interacting, never thermalizes. In this Many-Body Localized State, the Quantum Matter is literally stuck in unrest: Science 349, 842 (2015)We have observed a novel state of matter that, despite being interacting, never thermalizes. Such Many-Body Localized States represent a new class of …
