In a recent article published in Physical Review Letters, a mixed team from the Universitat Politècnica de Catalunya (UPC) and the Universitat de Barcelona (UB), present a microscopic theory of bound quantum droplets that explains their formation.

Huixia Lu and Jordi Marti from the SIMCOM research group of the Physics department publish an article on the anchoring mechanism to the cell membrane of certain proteins relevant to oncological studies

Sandeep Babu Gawali defended his thesis co-directed by Kestutis Staliunas and Jose Trull on December 17 at the Terrassa Campus. Titled "Intracavity spatial filtering in broad area semiconductor lasers", the thesis presents a study on the improvement of the spatial quality of laser beams emitted by high-power semiconductor lasers using photonic crystal filters implemented inside the laser cavity

Teng Wang defended his thesis titled "A Fasto Engineering Approach High Efficiency Power Amplifier Linearization for Avionics Applications" on December 17 at EETAC, directed by Pere L. Gilabert (TSC-UPC). The thesis provides some guidelines for the design of linearizers based on digital predistortion (DPD) from several perspectives: y) improve the performance of open-loop DPD, ii) provide robustness and reduce the computational complexity of the parameter identification subsystem and, iii ) incorporation of machine learning techniques to favor the auto-tuning of power amplifiers and DPD linearizers with various degrees of freedom to be able to maximize energy efficiency while meeting linearity specifications.

Juan Sánchez-Baena defended his thesis co-directed by Jordi Boronat Medico and Ferran Mazzanti Castrillejo on December 14 at the North Campus. Titled "Correlations to ultrafreds quantum gases with spin-orbit coupling", the thesis presents a study on the effect of correlations induced by interactions between particles on systems that are under the influence of spin-orbit potentials.

Hadrien Calmet will defend his thesis directed by Dr. Guillaume Houzeaux and tutored by Dr. Daniel Calvete at the campus nord. Titled “Large-scale CFD and micro-particle simulations in a large human airways under sniff condition and drug delivery application,” the thesis presents results that set a precedent for large-scale airway simulations and provide a better understanding of the mechanisms. physiological

Haixia Lyu telematically defended her thesis supervised by Professor Manuel Hernández-Pajares on November 17, 2020, entitled "Contributions to ionospheric modeling with GNSS in the mapping function, tomography and characteristics of polar electronic content." The thesis focuses on determining the vertical distribution of low- and high-resolution electron content from data from global positioning systems, GNSS (such as the American GPS) taken from terrestrial receivers and aboard orbiting satellites. low, and to improve knowledge of the climatology of the ionosphere in the polar and mid-latitude northern regions
