The paradigm of a particle with constant eternal acceleration has long influenced thinking in a number of directions, from the question as to whether an accelerating particle radiates, to the quantum mystery of Unruh radiation, to the question as to how EPR entanglement can be encoded in the classical geometry of the gravity dual of a quantum field theory. This talk will revisit this paradigm in the context of N=4 Yang-Mills theory where the important question of quantum field theory interactions can be studied both in perturbation theory and at strong coupling using AdS/CFT, with some surprising conclusions. |
