Constantino Tsallis

Constantino Tsallis, Greek-born Brazilian physicist (Athens 05 November 1943 – ACHIEVEMENTS  Regarded as one of the world’s most remarkable authorities on statistical physics  (over 10, 000 citations) Created the non-extensive statistical mechanics and formulated q-entropy, a new definition of entropy (1988) Established the notion that entropic extensivity requires the use of the nonadditive entropy for some classes of systems Identified a set of numbers for a system described by nonextensive statistical mechanics the q-triplet (2004) With Levy enunciated the concept of thermal transmissivity, a transmissivity variable which extends for thermal magnetic systems (1981) With M.C.S. Vieira discovered the gap road to chaos, a discontinuous map with amplitude asymmetry (1987) With G.A. Tsekouras introduced spectral statistics (2005) Conjectured the break-collapse method, an operational procedure (1981) Formulated microeconomic models with international repercussion With A.
