Clocking electrons racing faster than light in glass
Living life in the fast lane can be tremendously exciting, giving us the ‘time of our lives’ but how long does it really last? Experiments at the Tata Institute of Fundamental Research (TIFR), Mumbai have answered this question for a bunch of electrons traveling faster than light (fasten your seatbelts!) through a piece of glass. This study, done in collaboration with the Rutherford Appleton Laboratory in the UK and Centre for Intense Laser Studies and Applications (CELIA) in France appeared in Physical Review Letters on 05 February 2018.
