Statistical Mechanics Seminar, R, Car, "Entangled protons in ice"

Wed, Oct 19, 2011, 2:00 pm to 3:30 pm
Abstract: Quantum fluctuations can drive phase transitions in ice. This happens when the protons tunnel between the two equivalent sites on a hydrogen bond. The corresponding dynamics is collective and dominated by strong local correlations originating from the ice rules. As a result, the state of the proton is entangled, an effect that can be measured in simulations and has experimental consequences.
