About this event
Elliott (ELL) 168. “Quantum Catastrophes ” Caustics are singularities arising from the natural focusing of waves. Examples include rainbows, gravitational lensing, freak waves at sea, and event horizons. At large scales these phenomena lead to singular patterns that can be described by catastrophe theory. However, zooming down to short scales one finds that the singularities are smoothed by universal interference patterns that obey a remarkable set of scaling relations. My group has been extending these ideas to quantum fields. The big question we are trying to answer is whether there are classical wave singularities that are not resolved by ordinary wave interference but that are instead regulated by second quantization? I will take you through some examples we have studied in the context of quantum spin chains and analogue black holes made with flowing Bose-Einstein condensates.
