|Some major open questions worthy of
Department of Physics
Surprisingly, the rate at which
Nature is posing us problems is greater than our ability to solve them.
- How much of this is our fault?
- Is our rate of generation of red herrings, and our ability
to get hung up on them, greater than either?
(Note the recent confirmation of old result that the loss angle- the
phase angle of the optical conductivity is constunt up to 8000 cm-1,
indicating an exact power law. Recent ideas suggest a connection to the
Gutzwiller projection of wavefunctions. )
- The nature and extent of the strange metal.
(In my opinion the nature of pseudogap is not an open question for
meaningful discussion. Nernst phenomenology is: two coherence scales!
(Andy Millis and Lev Ioffe's fat cores))
(Note strong 3/4 intensity suggests pairs: 4x4=(2x2) X (2x2).)
- The "4x4" structure seen in STS.
Other important areas of quantum correlated matter:
(Low-density case the most interesting( Na>1/2): wrong
area of FS, thermopower obeys Heikes. A totally new
(U<Uc likes superconductivity. Are they the same in any
sense? Are they responsible for pressure-induced SC in organics?
- Capone phenomenon and Gossamer superconductivity:
For something entirely
different: has anyone been paying attention to the relativistic
heavy ion collider physics (RHIC)?
They are busy discovering a totally unexpected strong-coupled
quantum fluid! (low viscosity, too few jets, good hydrodynamics)
