Daniel L. Stein (born August 19, 1953), American physicist, is Professor of Physics and Mathematics at New York University. From 2006-2012 he served as the NYU Dean of Science. He has contributed to a wide range of scientific fields. His early research covered diverse topics, including theoretical work on protein biophysics, biological evolution, amorphous semiconductors, quantum liquids, topology of order parameter spaces, liquid crystals, neutron stars, and the interface between particle physics and cosmology. His primary focus, however, has been on quenched randomness in condensed matter and on stochastic processes in both irreversible and extended systems. His research on these topics was cited by the American Association for the Advancement of Science as "pioneering work on the statistical mechanics of disordered and noisy systems". He is best known for work on hierarchical dynamics (in collaboration with Elihu Abrahams, Philip Warren Anderson, and Richard Palmer);〔"Models of Hierarchically Constrained Dynamics for Glassy Relaxation", R.G. Palmer, D.L. Stein, E. Abrahams, and P.W. Andrerson, Phys. Rev. Lett. 53, 958-961 (1984).〕 for observing that protein fluctuational conformations can be modeled using spin glass techniques;〔"A Model of Protein Conformational Substates", D.L. Stein, Proc. Natl. Acad. Sci. 82, 3670 -- 3672 (1985).〕 for constructing a theory of fluctuation-driven transitions in the absence of detailed balance (in collaboration with Robert Maier);〔"Effect of Focusing and Caustics on Exit Phenomena in Systems Lacking Detailed Balance", R.S. Maier and D.L. Stein, Phys. Rev. Lett. 71, 1783 -- 1786 (1993).〕 for applying stochastic methods to determine lifetimes, stability, and decay of nanowires〔"Theory of Metastability in Simple Metal Nanowires", J. Buerki, C.A. Stafford, and D.L. Stein, Phys. Rev. Lett. 95, 090601-1--090601-4 (2005).〕 and nanomagnets〔"Magnetic Reversal in Nanoscopic Ferromagnetic Rings", Kirsten Martens, D.L. Stein, and A.D. Kent, Phys. Rev. B 73, 054413-1--054413-10 (2006).〕 (with a variety of collaborators); and for a series of rigorous and analytical results (largely with Charles M. Newman) on short-range spin glasses,〔"Non-Mean-Field Behavior of Realistic Spin Glasses", C.M. Newman and D.L. Stein, Phys. Rev. Lett. 76, 515 -- 518 (1996).〕〔"Topical Review: Ordering and Broken Symmetry in Short-Range Spin Glasses", C.M. Newman and D.L. Stein, Journal of Physics: Condensed Matter 15, R1319 -- R1364 (2003).〕 including the introduction of the Newman-Stein metastate as a general mathematical tool for analyzing the thermodynamic properties of disordered systems.〔"Metastate Approach to Thermodynamic Chaos", C.M. Newman and D.L. Stein, Phys. Rev. E 55, 5194 -- 5211 (1997).〕 ==Education & early career== Stein graduated from Brown University in 1975 with degrees in both physics and mathematics. He received his Ph.D. in Physics from Princeton University in 1979, under the thesis supervision of Philip Warren Anderson. He stayed on as a faculty member in the Princeton Physics Department until 1987, when he moved to the University of Arizona Physics Department, where he served as Department Head from 1995-2005. During that period he also served as the first Director of the Complex Systems Summer School in Santa Fe (1988, 1990–1998). In 2005 he moved to New York University as Professor of Physics and Mathematics and as Provost Faculty Fellow. He became the NYU Dean of Science in September 2006, serving until 2012. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Daniel L. Stein」の詳細全文を読む スポンサード リンク
