Christof Wetterich is a German theoretical physicist. Born 1952 in Freiburg (Germany), he studied physics in Paris, Cologne and Freiburg, where he received his PhD in 1979. He worked at CERN in Geneva and DESY in Hamburg. Since 1992 he has a chair for theoretical physics at Ruprecht-Karls-Universität Heidelberg. His major research interests are cosmology and particle physics. The development of the theoretical method of functional renormalization by Wetterich has found applications in many areas of physics, e.g. it provides a suitable framework to study quantum gravity (asymptotic safety),〔 (''Nonperturbative evolution equation for quantum gravity'' ), M. Reuter, Phys. Rev. D 57, 971 (1998), (arXiv:hep-th/9605030v1 ) 〕 Yang-Mills theories〔 (''Effective average action for gauge theories and exact evolution equations'' ), M. Reuter and C. Wetterich, Nucl. Phys. B 417, 181 (1994) 〕 and it was also useful in non-relativistic quantum systems like the BCS to BEC crossover where it ''bridges'' the two theories in a unified theoretical language.〔 (''Flow equations for the BCS-BEC crossover'' ), S. Diehl, H. Gies, J.M. Pawlowski, and C. Wetterich, Phys. Rev. A 56, 021602(R) (2007), (arXiv:cond-mat/0701198v2 ) and (''Functional renormalization group approach to the BCS-BEC crossover'' ), S. Diehl, S. Floerchinger, H. Gies, J. M. Pawlowski, and C. Wetterich, Ann. Phys. 9, 615 (2010), (arXiv:0907.2193v2 ) 〕 Wetterich is best known for his proposal〔 (''Cosmology and the Fate of Dilatation Symmetry'' ), C. Wetterich, Nucl. Phys. B 302, 668 (1988)〕〔 ''The Cosmon Model for an Asymptotically Vanishing Time Dependent Cosmological "Constant"'', C. Wetterich, Astron. Astrophys. 301, 321 (1995), (arXiv:hep-th/9408025v1 )〕 of dynamical dark energy or quintessence in 1987. This could explain the observed accelerated expansion of the Universe. He has done fundamental work for the theoretical understanding of tiny masses of neutrinos.〔 (''Neutrino Masses and the Scale of B-L Violation'' ), C. Wetterich, Nucl. Phys. B 187, 343 (1981)〕〔 (''Proton Lifetime and Fermion Masses in an SO(10) Model'' ), G. Lazarides, Q. Shafi, and C. Wetterich, Nucl. Phys. B 181, 287 (1981)〕 The method of functional renormalization relates macro physical structures to micro physical laws in a continuous way. Its modern form is based on the exact ''Wetterich equation''.〔 (''Exact Evolution Equation for the Effective Potential'' ), C. Wetterich, Phys. Lett. B 301, 90 (1993);〕〔 (''Non-perturbative Renormalization Flow in Quantum Field Theory and Statistical Physics'' ), J. Berges, N. Tetradis, and C. Wetterich, Phys. Rept. 363, 223 (2002), (arXiv:hep-ph/0005122 )〕 ==Honours and awards== Wetterich received the ''Max-Planck Research Prize''〔 There exists a short public (video ) (German) as a film portrait to the winners in addition. 〕 in 2005. Since 2006 he is member of the Heidelberg Academy of Sciences.〔 (Portrait ) at the (HAW homepage ). 〕 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「Christof Wetterich」の詳細全文を読む スポンサード リンク
