Delta-kick Squeezing enables Quantum-enhanced atom interferometry (Robin Corgier / LCAR / Seminar). – 18/11/22, 11H30

Amphi CONCORDE, Bâtiment U4 Amphithéâtre Concorde - Université Paul Sabatier, Toulouse, France

Robin Corgier (LNE-SYRTE, Observatoire de Paris, Université PSL, CNRS, Sorbonne Université, Paris, France) Summary : The possibility to overcome the standard quantum limit (SQL) by engineering specific quantum correlations between the atoms is attracting increasing interest in the field of atom interferometry. Recently, Bose-Einstein condensates (BECs) have been pinpointed as optimal candidates for the realization… Read More »Delta-kick Squeezing enables Quantum-enhanced atom interferometry (Robin Corgier / LCAR / Seminar). – 18/11/22, 11H30

Brève histoire de l’intrication quantique depuis Euler – (Grzegorz Rajchel-Mieldzioć / Seminar / LPT). – 22/11/2022

salle de séminaire 3ème étage Bâtiment 3r1 Université Toulouse III, Toulouse, France

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

Trions and Fermi-polarons in 2D semiconductors (Mikhail Glazov / Seminar / LPT). – 29/11/2022, 14H

salle de séminaire 3ème étage Bâtiment 3r1 Université Toulouse III, Toulouse, France

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

Modelling low-energy electron induced chemistry (Fabris Kossoski / LCPQ / Seminar) – 01/12/2022, 14 H

salle de séminaire 3ème étage Bâtiment 3r1 Université Toulouse III, Toulouse, France

Fabris Kossoski, post-doc, LCPQ Summary : The encounter of a low-energy electron with a molecule gives rise to electron-induced chemistry, which is known to play key roles in fields as diverse as radiobiology, material sciences, astrochemistry, and plasma-based technologies. However, there are still major open questions about the underlying mechanisms of molecular dissociation. This project… Read More »Modelling low-energy electron induced chemistry (Fabris Kossoski / LCPQ / Seminar) – 01/12/2022, 14 H
