Anna Spanoudaki is a researcher known for her participation in experiments on the superluminal (faster-than-light) velocity of signals in photonic tunneling. She is listed in The Worldwide List of Dissident Scientists.
Work
Spanoudaki was a co-author, with Horst Aichmann, Andreas Haibel, W. Lennartz and Günter Nimtz, of the paper "Demonstrating Superluminal Signal Velocity", presented at the International Symposium on Quantum Theory and Symmetries (18–22 July 1999) and published in its proceedings in 2000. The work belongs to the program of microwave and photonic tunneling experiments carried out by Nimtz's group at the University of Cologne, in which evanescent modes crossing a barrier were reported to propagate with group and signal velocities exceeding the speed of light. The interpretation of these results as genuine superluminal signalling lies outside the scientific mainstream, which holds that such experiments do not permit faster-than-light transfer of information and do not violate special relativity or causality.
