Recently Grecia Guijarro has defended her PhD thesis under supervision of Jordi Boronat and Grigory Astrakharchik in the research group "Approaches to the first principles in condensed matter physics: quantum effects and complexity". The theoretical prediction of existence of a novel type of a quantum ultradilute liquid has been published in Physical Review Letters journal. It was found that dipolar interactions on their own are sufficient for creating an ultradilute quantum liquid in a bilayer geometry.

Professor Alberto Rebassa of the Department of Physics at the UPC leads, together with Dr. Odette Toloza of the Universidad Técnica Federico Santa María, Chile, a team of 30 researchers from 18 institutions around the world to obtain and analyze the spectra of 77,000 stars. in a telescope of the southern European observatory located in Chile.

Judith Medina defended her thesis co-directed by Muriel Botey and Ramon Herrero on November 30 at the Terrassa Campus. Titled "Smart control of light in EEL lasers", the thesis presents different proposals to achieve a stable and focused emission of semiconductor lasers.

Yago Herrera defended his thesis co-directed by Glòria Sala and Jordi José on December 15 at the Diagonal-Besos Campus. Titled "Models of stellar winds from X-ray bursts", the thesis presents a study on the possible ejection of mass through a stellar wind during X-ray bursts, quantifying its composition and possible contribution to galactic abundances, and characterizing observables magnitudes that can lead to better measuring techniques of neutron stars properties.

Yuri Kubyshin from NEMEN research group along with physicists from the Skobeltsyn Institute of Nuclear Physics of the Moscow State University have published a paper devoted to an analysis of beam dynamics in electron accelerators of the racetrack microtron (RTM) type and searching for improvements of their characteristics.

PhD student Gerard Pascual and professor Jordi Boronat of the research group Approaches to the first principles in condensed matter physics: quantum effects and complexity; have published a paper in the journal Physical Review Letters, where it is theoretically described how a polaron, the result of the interaction of an impurity with a gas of bosons in the condensation phase, disappears due to the effect of temperature

Jonathan Fernando Gebbia defended his thesis co-directed by Josep Lluís Tamarit and Michela Romanini on October 6th at the Besòs campus (EEBE). Titled "Emerging glassy properties in molecular crystals", the thesis presents the study of low temperature anomalies of glasses found in different molecular crystals by means of low temperature calorimetry, inelastic neutron scattering, and simulations based on ab-initio DFT
