SUMMARY:Quantum phase transitions and novel phases. - Philipp Gegenwart\, 
 University of Goettingen
DTSTART:20100429T131500Z
DTEND:20100429T141500Z
UID:TALK23816@talks.cam.ac.uk
CONTACT:Michael Sutherland
DESCRIPTION:The phenomena occurring at the disappearance of a magnetically
  ordered state\nupon tuning a non-thermal parameter like pressure\, compos
 ition\, or magnetic\nfield are presently among the central topics in the f
 ield of strongly\ncorrelated electron systems. Quantum criticality in meta
 ls not only leads to\na breakdown of Fermi liquid theory but could also pr
 omote the formation of\nnovel (quantum) phases like spin-liquid behavior\,
  unconventional\nsuperconductivity or electronic nematic ordering. In the 
 talk\, I will discuss\nrecent low-temperature thermodynamic and transport 
 experiments on f-electron\nbased heavy-fermions\, ruthenates and iron pnic
 tides.
