Physics Colloquium, February 14, 2006Duality Symmetry: The Case of the Theory That Worked Too WellDan ShaharWeizmann Institute of Science, IsraelNear quantum phase transitions, in which a quantum system abruptly changes its ground state in response to a change of an external parameter, electronic systems exhibit remarkable symmetries that relate the properties of one phase to those measured in the other. In this talk I will demonstrate the existence of these symmetries and argue their relevance to the charge-flux duality symmetry theoretically suggested for such systems. 4:00 p.m., Physics Research Building (PRB), Room 1080Reception at 3:45 p.m., Atrium, PRB |
