CONDENSED MATTER THEORY CENTER CMTC is a small

CONDENSED MATTER THEORY CENTER • CMTC is a small QCMT center • Created for the retention of Das Sarma in 2002 by UMD and LPS-NSA under a joint agreement • State funding: $120, 000 per year • NSA funding: $120, 000 per year • Other federal funding: $800, 000 per year (SDS) • Main purpose is to have a lot of ‘youth’ doing research, i. e. a lot of postdocs/students; fund sabbatical visitors; support seminars/travel, etc. CMTC is a mini-ITP on a much smaller scale with just the high-quality research component CMTC Das Sarma March 2005

CMTC Goal: Create the best ‘small’ theory center for solid state research on quantum computation, quantum devices, semiconductor nanostructures Quantum coherence Quantum transport Quantum phases Quantum many-body theory CMTC Das Sarma March 2005

AGREEMENT REGARDING THE ESTABLISHMENT OF THE CONDENSED MATTER THEORY CENTER (CMTC) The following agreement constitutes a commitment between the “Collaborating Institutions” (referring to the Laboratory for Physical Sciences and the Department of Physics with the support of the College of Computer, Mathematics and Physical Sciences (CMPS) and the University) and “the Director, ” Dr. Sankar Das Sarma to create a new Condensed Matter Theory Center (CMTC) with an annual budget of $240, 000 beginning in July 2002. The goal of the new CMTC will be to develop a center of excellence to attract additional outstanding condensed matter theorists to the Collaborating Institutions. The Center will undergo periodic reviews by the Department of Physics (every five years) to assess and help improve its effectiveness. Starting on July 1, 2002, the University will provide $120, 000 annually and the Laboratory for Physical Sciences (LPS) will also provide $120, 000 (pursuant to the specific rules, regulations and State and Federal laws that apply at each institution) bringing the total Collaborating Institution funding for the Center to $240, 000 annually. The CMTC will also be eligible for increased funding in the future (i. e. , to accommodate inflation) in accordance with future deliberations of the Collaborating Institutions. The Center funds will be used primarily to hire postdoctoral researchers, to support short-term and long-term visitors, to bring lecturers and seminar speakers to the department, and to support Ph. D. students of exceptional merit as Research Fellows. Within these guidelines, CMTC funds may also be used for various research support activities such as travel, clerical and secretarial support, publication and communication expenses, to contribute to new faculty start-up packages, and other allowable professional expenses associated with university research. The Director will begin a permanent appointment with the new CMTC on July 1, 2002 and will be responsible for carrying out all the necessary day-to-day activities of the Center. The Department of Physics will allocate appropriate space for the CMTC. The Center’s activities will be guided by and must conform to all of the appropriate rules as set out in policies at both the University of Maryland the Laboratory for Physical Science.

The Condensed Matter Theory Center (CMTC) was created in 2002 by the University of Maryland with the Distinguished University Professor Sankar Das Sarma as its permanent Director. The support for CMTC comes from the University of Maryland the Laboratory for Physical Sciences (LPS). The sole purpose of CMTC is to maintain sustained excellence in theoretical condensed matter physics (defined in the broadest possible sense) at the University of Maryland. In addition to carrying outstanding research in condensed matter theory, CMTC will also occasionally host distinguished lectures by the leading researchers, and may organize small research workshops on important topics. CMTC has funds for research fellows and associates at postdoctoral level (2 -5 years appointments), for short-term (1 week to 6 months) visitors, for long-term (1 year or more) senior sabbatical visitors, and for research fellowships for outstanding graduate students. The goal of CMTC is to have the best possible scientific quality in its members (and to foster creative interaction among them) so as to produce a highly visible and active (small) theory center. Junior and senior scientists interested in CMTC positions should contact the Director in writing. CMTC Das Sarma March 2005
