Principal Investigator:Romain Pierre Marcel Bachelard
Grantee:Tiago Santiago do Espirito Santo
Host Institution: Instituto de Física de São Carlos (IFSC). Universidade de São Paulo (USP). São Carlos , SP, Brazil
Associated scholarship(s):19/02071-9 - Beyond the linear optics limit: quantum effects in a ultracold dilute cloud, BE.EP.DD


This project corresponds to the final phase of the Direct PhD of the candidate, which started in July 2015, and will end in July 2018 due to the conclusion of the Young Researcher Project of the supervisor. The candidate will conclude three projects which are well advanced. The first addresses subradiance and superradiance in clouds of saturated atoms. The second, initiated during a BEPE internship, deals with cooperative broadening of linewidths. The third one is about the propagation of quantum correlations in ultracold clouds, due to the presence of long-range interactions. (AU)
