Ada Altieri

Postdoc (funding: Simons Grant, November 2018 – present)
Working with Giulio Biroli 

Ada Altieri obtained her PhD in Theoretical Physics in February 2018 both from the University of Rome “Sapienza” and the University Paris-Sud XI (cotutelle de thèse) co-advised by Giorgio Parisi and Silvio Franz respectively. During her doctoral studies she focused, on the one hand, on renormalization group techniques in disordered systems and, on the other hand, on the connections between continuous constraint satisfaction problems and the jamming transition in high dimension.   Then, in November 2017 she moved to the Laboratoire de Physique Théorique at École Normale Supérieure, in Paris, where she started a one-year postdoc with Francesco Zamponi working on the rheology of amorphous solids under shear deformations.

Since November 2018 she is a postdoctoral researcher in the team of Giulio Biroli, working both on glassy systems and on the investigation of collective and critical behaviors in large ecosystems.

Francesco Arceri
PhD student (September 2017-present)
Working with Eric Corwin

Francesco is studying the structure of packings subject to an effective logarithmic interparticle potential, predicted to be the effective mean-field free energy for hard sphere glasses. The purpose of his research is to create equilibrium thermal configurations of hard spheres using a zero temperature compression protocol which minimises the logarithmic potential. Doing so it is possible to obtain packings at densities inaccessible with conventional simulation schemes.

Francesco received his master degree in Theoretical Physics in January 2017 from “La Sapienza” University of Rome, Italy. During his master he focused his interests on disordered systems, in particular studying models to describe glasses working with Federico Ricci-Tersenghi.
