Electromagnetically induced transparency ~EIT! has been studied primarily within the context of multilevel atomic systems. We show that EIT can occur also in a two-level atomic system and can lead to strong self-action and slow-light effects that are not hampered by material absorption, with important potential implications for processes such as squeezed-light generation and the propagation of ...

Sensitive radio observations of the 1997 September 24 EIT wave show its velocity to be 830 km s−1. The wave first appears a short distance from the flare site, and its trajectory projects back to the flare site at the peak of the impulsive phase. The radio spectrum appears to be consistent with optically thin coronal emission rather than chromospheric emission. The observed radio brightness tem...

A strong coupling standing wave, interacting with three-level L-type ~or ladder-type! atoms, can diffract a weak probe field ~propagating along a direction normal to the standing wave! into high-order diffractions, a phenomenon which we name electromagnetically induced grating ~EIG!. We develop in this work a theory for studying EIG in a homogeneously broadened medium consisting of three-level ...

Digital Cities. The report includes scenarios, trends, challenges and recommendations for further TDCT activities and carrier project proposals. The content is input to the TDCT Foresight Studies lead by professor Magnus Boman (EIT ICT Labs catalyst leader for Innovation Radars).

The Semantic and Knowledge Innovation Lab (SKIL) is an innovation lab opened by TELECOM Italia as a result of its partnership with the European Institute of Technology (EIT). The lab is located in Trento which hosts one of the 6 Information and Communication Technologies Lab of the EIT and two reference research groups: University of Trento and the Fondazione Bruno Kessler (FBK) center. The aim...
