Universal scaling of fluctuations and correlations across the superfluid transition
Paul Paquiez, Géraud Dupuy, Maxime Allemand +6
The critical behavior of a system near a continuous phase transition is commonly characterized by power laws and a set of universal critical exponents. Yet universality at phase tr…
Connected correlations in cold atom experiments
Thomas Chalopin, Igor Ferrier-Barbut, Thierry Lahaye +2
The recent development of single-atom-resolved probes has made full counting statistics measurements accessible in quantum gas experiments. This capability provides access to high-…
Observation of universal non-Gaussian statistics of the order parameter across a continuous phase transition
Maxime Allemand, Géraud Dupuy, Paul Paquiez +5
Second-order phase transitions are characterised by critical scaling and universality. The singular behaviour of thermodynamic quantities at the transition, in particular, is deter…
Quantifying two-mode entanglement of bosonic Gaussian states from their full counting statistics
Victor Gondret, Clothilde Lamirault, Rui Dias +4
We study the entanglement properties of two-mode bosonic Gaussian states based on their multi-mode counting statistics. We exploit the idea that measuring high-order correlations o…
