It was a pioneer initiative in Theoretical Physics, whose aim was to promote research activities and to train young researchers in the area. In the 50's, the institute received several foreign long term visitors, such as Prof. Carl Friedrich von Weizsacker (first director), Wilhelm Macke and Reinhard Oehme, from the Max Planck Institut fur Physik, Gottingen, Prof. Gert Moliere (also director), Prof. Hans Joos from the Tubingen University and Prof. Werner Giittinger from Aachen, among others. At the end of that decade, Prof. Mituo Taketani from the Rikkyo University, Tokyo, assumed the direction of the institute and brought several Japanese physicists ( e.g. Prof. Yasuhisa Katayama, Tatouki Miyasima, Jun'ichi Osada). In 1958, the Instituto de Ffsica Teorica started to edit the bulletin "Informacao entre Ffsicos" which would give rise to the "Brazilian Journal of Physics". In 1962, Prof. Paulo Leal Ferreira became the first Brazilian director of the institute. After being declared a "Center of Excellence" by the National Research Council (CNPq), the Instituto de Ffsica Teorica began offering Graduate courses in Physics in 1971, and to this moment more than 50 Ph.D. and 100 Master degrees have been bestowed. In the nation wide rankings of the Brazilian Ministry of Education, the graduate studies program of IFT is considered as one of the best in the nation. In the 80's, after a severe economical crisis, the Instituto de Ffsica Tedrica was incorporated to the State University of Sao Paulo (UNESP). The Foundation still remains as an autonomous entity and maintains the buildings and the library. Nowadays, the Instituto de Ffsica Teorica is one of the most productive Brazilian research insti- tutions and has scientific collaborations with several international centers. The research subjects include Mathematical Physics, Field Theory, Elementary Particle Phenomenology, Cosmology and Gravitation, Nuclear Physics, Statistical Mechanics, and Nonlinear Dynamics. The scientific staff has 30 researchers and the Graduate course more than 46 students pursuing Master and Ph.D. degrees. 1.2 Research Facilities 1.2.1 Library The Institute has one of the best Brazilian libraries in theoretical physics. It has around 14.469 books covering the areas of mathematics, the physics of elementary particle and fields, nu- clear physics, mathematical physics, cosmology and gravitation, statistical mechanics, condensed matter and atomic physics. It subscribes more than 79 journal titles. 1.2.2 Computing Facilities The Instituto de Ffsica Teorica has a computer center with a processing capacity of around 500 Mflops. The computing facility includes 1 digital AXP server, 1 high end server RS6000 IBM, 1 high performance paralell server SUN HPC, 5 high performance workstation RS 6000 IBM, SUN SPARC, 40 microcomputers e x-terminals e 14 printers, 20 medium performance workstations RS6000 IBM, 26 microcomputers, 14 printers. The local network is linked via TCP/IP and is connected with the international network via InterNet trough a 256Kbps line. Algebraic software (MathCad, Mathematica, Mapple) and mathematical libraries (IMSL, CERN) besides printing facilities (HP LaserJet IHSi , HP LaserJet II , Laser Print IBM) are available for the whole network. 1.3 Main Lines of Research 1.3.1 Field Theory Higher spin algebras in conformal field theory, W algebras, conformal field theory and inte- grable models in two dimensions, string field theory, Jacobi equations in field theory, symmetries of Toda models and soliton solutions, field theory in curved space, integration in negative dimensions, causal approach and field theory, constrained dynamics and applications. 1.3.2 Elementary Particle Physics Standard model phenomenology, search for new particles and interactions, alternative models for electroweak interactions, neutrino physics.radiative corrections and precision eletroweak mea- surements, vector boson anomalous couplings, astroparticles, relativistic hadronic models, phe- nomenology of quark-gluon plasma signatures, instantons and hadronic spectroscopy, two-body relativistic equations. 1.3.3 Nuclear Physics Nuclear fission, microscopic nuclear models, semiclassical many-body methods, few-body problems, nuclear structure, fusion of heavy ions, electron scattering, giant resonances, restrict dynamic models, nuclear matter at high temperature and densities, hadronic structure, extensions of RPA method, many neutrons nuclei, relativistic many-body methods, q-deformed algebras and many-body physics. 1.3.4 Gravitation and Cosmology Relativistic cosmology, quantum gravity, gauge models as alternative theories for gravitation, classical and quantum fields in curved space-time. 1.3.5 Mathematical Methods in Physics Quantum phase spaces, non-commutative geometry in quantum mechanics and many-body systems, quantum groups and invariant forms, quantization structures, singular potentials in quantum mechanics, renormalization in quantum mechanics. 1.3.6 Non—linear Phenomena Integrable models, soliton equations, chaotic dynamical models and perturbation theory. 1.3.7 Statistical Mechanics Polymer conformation models, superconductivity at high temperatures, combinatorial meth- ods, quantum groups and critical phenomena. 1.3.8 Atomic Physics Positron-atom scattering at low and medium energies. 2 Personnel 2.1 Faculty Abraham H.
