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…

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…

Tomography of a single-atom-resolved detector in the presence of shot-to-shot number fluctuations
Maxime Allemand, Raphael Jannin, Géraud Dupuy +4
Tomography of single-particle-resolved detectors is of primary importance for characterizing particle correlations with applications in quantum metrology, quantum simulation and qu…
