Mateo Uldemolins-Nivela (LPS, Orsay)   Summary A magnetic impurity on a conventional superconductor is one of the most simple pair-breaking defects that induces in-gap Yu-Shiba-Rusinov (YSR) bound states, whose intricate spatial structure crucially influences the possibilities of engineering collective impurity states (e.g., Shiba chains, lattices...) and topological superconductivity. In this talk, I will first introduce… Read More »Yu-Shiba-Rusinov states in two-dimensional superconductors. – (Mateo Uldemolins-Nivela / Seminar / LPT). – 08/11/2022

Maxime Rovère (IHRIM, Lyon) Summary While physics has undergone intense upheavals throughout the 20th century, the way philosophers think of human action seems to rely on notions (responsibility, freedom, etc.) most of which do not take into account the new tools of reason. On the contrary, the most common discourses on human actions and emotions… Read More »Chaos et complexité : comment appliquer à l’éthique humaine la rationalité des sciences contemporaines ?- (Maxime Rovère / Seminar / LPT). – 10/11/2022

Grzegorz Rajchel-Mieldzioć (ICFO Barcelone) The negative solution to the famous problem of 36 officers of Euler implies that there are no two orthogonal Latin squares of order six. We show that the problem has a solution, provided the officers can be entangled and construct two quantum orthogonal Latin squares of this size. In other words,… Read More »Brève histoire de l’intrication quantique depuis Euler – (Grzegorz Rajchel-Mieldzioć / Seminar / LPT). – 22/11/2022

Mikhail Glazov, Institut Ioffe, Saint-Pétersbourg Summary : Recently emerged two-dimensional semiconductors based on transition metal dichalcogenides demonstrate spectacular properties and are considered as materials beyond graphene for optoelectronics, spintronics, valleytronics, and straintronics. Optical response of these atom-thin semiconductors is dominated by the excitons — Coulomb bound electron hole pairs. Strong Coulomb interaction makes it also… Read More »Trions and Fermi-polarons in 2D semiconductors (Mikhail Glazov / Seminar / LPT). – 29/11/2022, 14H
