Dr. Deffner publishes a new paper in Physical Review Letters. Together with Prof. Steve Campbell from the University College Dublin, and Dr. Tomas Fogarty and Prof. Thomas Busch from the Okinawa Institute of Science and Technology, Dr. Deffner showed that by studying the quantum speed limit the orthogonality catastrophe (an important property of non-trivial many particles systems) can be understood, and it simply follows from Heisenberg's energy-time uncertainty principle.

“Orthogonality Catastrophe as a Consequence of the Quantum Speed Limit”
