Exploring the Supersolid Phase of Matter with a Dipolar Quantum Gas

The supersolid is a paradoxical quantum phase of matter that counterintuitively combines the properties of solids and superfluids. Despite the concept of supersolidity was introduced more than 50 years ago, its experimental verification has been elusive. Only very recently, supersolid properties have been detected in an ultracold quantum gas of magnetic atoms — a system apparently very different from both quantum liquids and solids. In this talk, I will discuss the fundamental steps that led to the discovery of supersolidity in dipolar quantum gases. I will then focus on few experiments, recently performed in our lab, highlighting the mixed solid and superfluid character of dipolar supersolids. It is now very exciting to have in the lab a new exotic quantum material with unprecedented properties to test.

Bio: Luca Tanzi is researcher at CNR-INO, Pisa unit, since 2019. Previously, he was postdoc at the University of Florence (2017-2019) and at ICFO (2014-2017). He studied Physics in Milan and he holds a PhD in atomic and molecular spectroscopy from LENS (2011-2014). His research activity mainly consists in frontier experiments on quantum phenomena with ultracold gases. His current focus regards the study of novel phases of matter, stabilized by the interplay of mean-field interactions and quantum fluctuations. He has published more than 15 articles on diverse topics including: disordered quantum systems, dilute quantum droplets, dipolar supersolids.
