**QUANTUM PHASES OF MATTER**

Currently, I am an Associate Professor working in the Physics Department, University of Catania. I am an associate member of CNR-MATIS Excellence Centre for Condensed matter and Material science, Italy; an associate member of the Istituto Nazionale di Fisica Nucleare (INFN), Italy. Since 2010, I am appointed Visiting Research Professor at the Centre for Quantum Thechnologies (CQT), Singapore. I hold the ‘Lanef -Chaire d’excellence’ in Grenoble and, finally, I am an ‘ Distinguished Invited Professor’, MajuLab CNRS-UNS-NUS-NTU France-Singapore joint lab.

As documented by my publications, I have established several international collaborations. In particular. I have forged strong connection with the Centre for Quantum Technologies in Singapore. I have formed a strong connection with CNRS - Laboratoire de Physique et Modélisation des Milieux Condensés, Grenoble, where I hold the ‘Lanef-Chaire d’excellence’. In such institutions, I have been leading international research teams. I have documented ability to obtain research funds. As attested in my cv, I am involved as participant/coordinator in several major Italian and International network grants from the start of my career.

Throughout my career I have been contributing to the research in diverse fields, particularly in the general area of quantum statistical physics, ranging from mathematical physics and quantum information to many-body and mesoscopic physics with close contacts with the experimentalists in the field (see the research statement attached to the present application). My work is well recognized by the scientific community (my papers have currently been cited more than 5200 times and hold an h-index of 26, data from SAO/NASA ADS).

I am recognized as one of the founding leaders in the cross-fertilization field between quantum information approaches and many-body systems ("*Scaling of entanglement close to quantum phase transitions"*, Nature **416**, 608 (2002); *"Entanglement in Many-Body Systems"*, Rev. Mod. Phys. **80**, 517-576 (2008). A major challenge in this context is to tell a part entanglement from usual correlations. In this context, I mention the very fruitfull collaboration with Prof. G. Aeppli. Together, we constructed an international collaboration and resources (Rutheford-Appleton Laboratories, Paul Scherrer Institute, University of Catania) to measure entanglement in quantum magnets through neutron scattering experiments. This study has the promise of being a seminal work that will lead to a whole new subfield of neutron scattering: the quantitative experimental study of the quantum information content of quantum magnets. Several experimental sessions were carried out already (in RAL and Paul Scherrer Institute in Zurich). We already published *“**Experimental implications of the entanglement transition in clustered quantum materials*”(Phys. Rev. B 96, 224408 (2017)); futher papers summarizing our findings are in preparation.

I am recognized as one of the founding leaders and one of the main driving force of the emerging field of cold-atom Quantum Technology that is known as __Atomtronics__ (*"Quantum many particle systems in ring-shaped optical lattices*", Phys.Rev.Lett. 95 (2005) 063201; *‘Atomtronics’*, J. Opt (2016)). I have been working intensively to propose Atomtronics as a new direction of fundamental research with ground-breaking applications in quantum technology. In short: Atomtronics seeks to realize circuits of ultracold atoms where the wires are replaced by laser light and/or magnetic guides. Elementary Atomtronic circuits have already been realized, mimicking both conventional electronics like diodes, PNP junctions and elements of quantum electronics such as Josephson junctions SQUID’s. Atomtronics, however, is not strictly limited to developing electronic-like components: it aims at providing new concepts of quantum devices, integrated in a circuitry that may be of a radically new type. With atomic flows and high flexibility in the confinement geometry offered by Atomtronics enlarges cold-atoms quantum simulators considerably: In the spirit of solid-state physics I-V (current-voltage) characteristics, we are able to define a new diagnostic of the different condensed matter quantum regimes, in terms of the current flowing through the cold atomic system. With such approach, we are expected to discover new features of quantum material science (condensed matter). The technological evolution I foresee is comparable to the development of electronics and silicon technology: its enormous success is based on visionary basic research whose impact became apparent about 50 years later. In the past 20 years, the advancement of information and communication technology has had a major impact on human culture and society, embracing not only all scientific disciplines but also our daily life. I think, I have been in the right time and in the right position to shape the field. Since then, the community enlarged considerably and it is gathered in the Atomtronics@Benasque workshops I have been organizing since 2015. Indeed, I am aware of few large scale efforts worldwide of high profile scientists that have the potential to definetely make the field as a major line in quantum technology: I do believe that it is just the right time to invest in Atomtronics. Currently, I have been acting as key player in medium and large scale research grants both in Europe and overseas.
