Space Physics and Solar-Terrestrial Relationship
The group of “Space Physics and Solar-Terrestrial Relationship”, at the Department of Physical and Chemical Sciences of the University of L’Aquila, has a long experience in the study of the effects of the solar wind and interplanetary magnetic field variability on the magnetospheric dynamics and geomagnetic activity. Since 2000 the group runs, in cooperation with the Space Research Institute (Austria), the South European GeoMagnetic Array (SEGMA). The array is part of the global magnetometer network ULTIMA (Ultra Large Terrestrial International Magnetic Array), an international consortium that aims at promoting collaborative research on the magnetosphere, ionosphere, and upper atmosphere through the use of ground-based magnetic field observatories. The group also runs magnetometer stations at Terra Nova Bay and Dome C in Antarctica. The group is also co-PI of the European quasi-Meridional Magnetometer Array (EMMA), a network of 27 stations extending from Italy to Finland which was established in 2012 through an FP7 European funding. The main research activities carried out by the group are the following:
- effects of the solar wind and interplanetary magnetic field variability on the magnetospheric dynamics;
- propagation of magnetohydrodynamic waves in the magnetosphere;
- remote sensing of the plasma mass density in the magnetosphere from geomagnetic field line resonances detected at magnetometer station networks;
- effects of the solar wind variability and of the related geomagnetic activity on atmospheric parameters at high latitudes;
- developments of models for the prediction of arrival times of coronal mass ejections (CME) at the Earth’s orbit.

Atmospheric Physics Group
The focus of the Atmospheric Physics group is the study of physical and chemical processes relevant to the composition and dynamics of the Earth’s atmosphere, aimed at studying climatic, meteorological and radiation field variability, with modeling and experimental tools. Most of the researchers are affiliated also to the Centre of Excellence in Telesensing of Environment and Model Prediction of Severe Events (CETEMPS, http://cetemps.aquila.infn.it/).
All the activities are carried out in the context of international collaborations, particularly with institutions in Europe and USA. The specific research topic include: understanding physical processes to improve operational meteorological and hydrological forecasting, improve reliability of global and regional climate models at the seasonal and decadal time scale, effects of human activities and natural phenomena on the degradation of air quality and the environment, remote sensing of the vertical profiles of the optical properties of atmospheric aerosols and water vapour.
The observational facility include two LIDAR stations, balloon-borne soundings, sunphotometer, a network of weather stations, air pollution monitors, with capabilities continuously expanding.

Statistical Mechanics Group
In our group we study the many body problem in both classical and quantum sysstems. We use analytical and computational techniques. The main computation efforts are directed to compherensio of quantum phases under extreme conditions. Metallic hydrogen among all, and its exotic phases.
Part of the group’s activity deals with the study of the different quantum phase transitions occurring in such models. Among the topics treated recently there are: disordered phases of spin-1 chains, topological phases in long-range interatcting systems, glassy phases in superfluid systems. Many-body systems are also studied from a Quantum Information perspective: both using the scaling of quantum correlations to characterize many-body systems and, conversely, using spin models as channels for Quantum Information transfer.
All the activities are carried on in collbotation with Italian and international institutions such as UFRN (Brasil), UAB (Spain), Univeristà della Calabria (Italy), University of Malta, Queen’s University Belfast (UK),
