Alberto Ghirri

Short Bio

Alberto Ghirri is a physicist, his background is in quantum magnetism, microwaves, electron magnetic resonance, calorimetry and surface science. He graduated in Physics in 2004 from the University of Modena and Reggio Emilia with a thesis on molecular magnetism and high magnetic field thermodynamic experiments (Grenoble HMFL) focused on the study of molecular antiferromagnetic clusters as spin qubits (Prof. M. Affronte), which has been awarded with the National Prize “Galluzzi” by Roma Tre University. In 2008 he received the PhD in Physics from the same University with an experimental thesis on the implementation of a low-temperature scanning Hall probe microscope for the ultrasensitive imaging of monolayers of magnetic nanoparticles. This work has been awarded with the National Prize “NEST for Nanoscience” by Scuola Normale Superiore of Pisa in 2009. In 2008 and 2009 he obtained two postdoc fellowships, respectively at UniMORE and CNR-NANO, for scanning probe and x-ray spectroscopic studies of spin clusters deposited on surfaces. In 2011 he has been visitor at the Max-Planck Institute in Stuttgart (2 months) for low temperature STM experiments. In 2012 he obtained a postdoc fellowship at the University of Milan (Prof. Lascialfari) for thermodynamic studies on spin clusters. In 2013 he has been scientific responsible of Modena unit of RBFR12RPD1 FIRB-Futuro in Ricerca 2012 project (2013-17, 336 keuro) with a young researcher position at CNR-NANO focused on the coherent coupling of molecular spin centers and superconducting microwave resonators. In 2014 (3 weeks) and 2016 (3 weeks) he has been visitor at the National High Magnetic Field Lab in Tallahassee (USA) for high frequency electron spin resonance spectroscopy (CNR STM Programme). In 2017 he obtained a CNR-NANO SEED grant (19 keuro) for implementing hybrid microwave circuits with semiconducting nanowire quantum dots in a YBCO coplanar resonator. Since 2018 he is permanent researcher at CNR-NANO in Modena.
