Marco Polini
Marco Polini is a CNR-INFM Researcher at the National Enterprise for nanoScience and nanoTechnology (NEST) in Pisa, Italy. He graduated in 1999 from the University of Pisa and received his Ph.D. in January 2003 from the Scuola Normale Superiore di Pisa. Immediately after, he went to work at the University of Texas at Austin as a visiting postdoctoral fellow until July 2003. In July 2003, he was hired at NEST as a tenure-track research scientist until December 2008, when he became permanent staff. Dr. Polini has mainly worked on two-dimensional electron liquids and ultracold atoms trapped in low-dimensional geometries, and he is a coauthor of over 60 publications. Since 2006 his work has mostly focused on the role of electron-electron interactions in single- and bi-layer graphene.
Spins in cold atoms—what a drag!
Interactions among noncondensed bosonic atoms in a trap can cause one species of atoms accelerated by a magnetic field to drag along another species of atoms that would normally not interact with the field. Read More »
