DESCRIPTION:I will talk about quantum phase transitions and critical expon
 ents in a special class of 2D quantum Heisenberg antiferromagnets.  In par
 ticular\, I discuss recent quantum Monte Carlo results on the "staggered" 
 Heisenberg model\, which has been discussed in relation to the exciting no
 tion of "deconfined quantum criticality".  By a detailed comparison to oth
 er dimerized models\, we show\, contrary to the current belief\, that the 
 critical exponents of the staggered model are most likely not in agreement
  with the 3D classical Heisenberg universality class.  I will also prenset
  further thermodynamic studies on the quantum criticial region which reinf
 orce these findings.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=
