My interests:

the role of disorder close to QPT, frustration in spin liquids, supercond. close to
QCP


Key open questions:

-is the new physics in heavy electron quantum crticality solely due to magnetism
or are there other modes?

-Detailed role of disorder close to "understood" QCP (like Hertz type spin
density wave transition with XY and Heisenberg symmetry)

-Is the spin-liquid state in organic kappa-Cu2(CN)3 a critical phase?

-what is the nature of the Non Fermi liquid state in MnSi?

Work I am doing:

-develop "infinite randomness" description for disordered itinerant
Heisenberg spins (with Th. Vojta)

-Understand / formulate a recently discovered strong coupling fixed point in
magnetic rotons as effective theory for MnSi

-formuate a mean field theory for  kappa-Cu2(CN)3.

-discuss with numerous people at the workshop what "other mode" may be of
relevance in YbRh2Si2 or YbAgGe...
