  1. 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 Biophysics Theme Group 1 THEORY Das Sarma

  2. PHENOMENA-DRIVENCondensed 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..

  5. 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 Theme Group 1 THEORY Das Sarma

  8. CONDENSED MATTER THEORY • 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!)

  9. CONDENSED MATTER THEORY • Collaborations • LOCAL • Das Sarma+ Chubukov + Yakovenko: a lot • Das Sarma + local experimentalists: a lot • Examples: Persistence (MRSEC); Magnetic oxides (CSR); Spin quantum computation (Drew, Kane) • Einstein + MRSEC : EXTENSIVE • Yakovenko + local experimentalists: some (Drew) • OUTSIDE • Das Sarma: DOE long-term permanent consultant (Sandia) • Das Sarma: Harvard, Yale, UCLA, Microsoft, Caltech, Weizmann, Princeton, Columbia, Melbourne, UCSB,… • Kirkpatrick: Belitz at Oregon (~20 years and still going strong) • Chubukov: Florida, Princeton, Paris, Argonne, Los Alamos • Yakovenko: Moscow • Einstein: Kansas/Iowa; Juelich, Chalmers, France Theme Group 1 THEORY Das Sarma

  14. 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) Theme Group 1 THEORY Das Sarma
