Theme Group 1 - Theory
• THEORETICAL CONDENSED MATTER & STATISTICAL PHYSICS
(Also AMO THEORY– does not yet exist!)
Strong, small, well-funded, highly visible, well-connected group
attracting some of the best graduate students and outstanding
postdocs in the department– has shrunk more in size than ANY
OTHER group in the last 10-20 years– spread over many units!
QUANTUM CONDENSED MATTER
MANY-BODY THEORY
STRONG CORRELATION PHYSICS
COLLECTIVE PHASES OF COLD ATOM SYSTEMS
“SOFT” CONDENSED MATTER:
Statistical Physics
Nonequilibrium Phenomena
Surface Physics

PHENOMENA-DRIVEN
Condensed Matter Physics has many ‘hills’ (i.e.
phenomena,topics,etc.), no single ‘mountain’
• Superconductivity; supefluidity; BEC
• Magnetic order (e.g. FM, AFM, RVB)
• Josephson effect, Kondo problem, Anderson
localization, Wigner solid, Abrikosov vortex
lattice,Luttinger liquid, Mott transition,…
• Coulomb blockade, weak localization,
conductance fluctuations, quant. interference
• Quantum Hall effects
• Quantum phase transitions
• Topological order;Nanoscience;MaterialsPhysics..
A VAST SUBJECT COVERING A LOT!
STRONG CONNECTION TO TECHNOLOGY: Spintronics, QC,…

Condensed Matter Theory
• Faculty History
A collection of 3+1 (3+1+1 with bio?) separate groups
scattered over 2 buildings: CMT, Stat Phys, MRSEC
(quantum condensed matter, classical stat physics,
surface physics, respectively), and AMO
Not a great deal of interaction between the three
subgroups (historically they have worked as separate
groups with distinct seminars, etc.)
AMO Theory is in the recruitment process (SDS:AMO)
Considerable AMO-QCMT interaction anticipated
Faculty : 11 (9+2) in 1982; 6 (4+2) in 2005
Postdocs: 4 in 1982; 11 in 2005

• Funding
– Das Sarma: ~$1,000,000 per year (NSF, ONR, ARO,
NSA, ARDA, DARPA, DOE)
– Chubukov, Kirkpatrick, Yakovenko: All have single-PI
NSF grants of >$100,000 per year each
– Fisher: Single-PI NSF grant ~$200,000 per year
– Einstein: Two NSF joint grants ~$100,000K per year
– TOTAL FUNDING >$1,500,000 per year (apparently
the most funded condensed matter theory group in
US)
– No umbrella grant covering the group (not yet!)

Condensed Matter Theory
• STRONG GROUP (#10 in US News; #8 in reality!)
(2 regular seminars+AMO seminar+CMTC talks)
• How can we improve? (Or not go down!)
>One more hire in the immediate future in
quantum condensed matter physics (this
year or next year– preferably at the full
professor level, purely in physics, not joint)
>Two assistant professor hires over
the next 3-5 years: 1 QCMT; 1 “soft”
>More (and better quality) space and some
university/departmental (state) funding (a nominal
amount of 100K per year state funds would go a
long way in further enhancing the group)
