Creating and sharing knowledge for telecommunications

Conftele 2015

on 17-03-2015

... The 10th Conference on Telecommunications, Conftele 2015, is embedded into a two days of technology discussions, called TECHDAYS Aveiro, from 17 to 18 of September, 2015. TECHDAYS Aveiro is organised by Instituto de Telecomunicações, Universidade de Aveiro, INOVARIA, and the Aveiro Municipality and will be held at Aveiro Expo, in Aveiro, Portugal, on September 17 and 18, 2015. The Conference is intended to be an international forum for the exchange of information among universities, research units, service providers, operators and manufacturers, on recent technical issues in telecommunications.

Strong coupling in quantum mechanical systems occurs when the strength of the coupling is much larger than losses. Such a feature can be found in optical cavities, where the atoms strongly couple to the cavity photonic modes (cavity QED). The same occurs in semi-conductor microcavities, where excitons strongly couple to photons. In these systems, the resulting quasi-particle, the so-called polariton, results from the hybridisation of a typical excitation with photons. In this talk, I will discuss two examples involving ultracold atoms where strong coupling involves a phonon mode, giving rise to an acoustic-like quasi-particle: the phonon-polariton. Some relations with the research in the domain of exciton-polaritons and its applications will be drawn.
