Power-law tailed spectra
• particles and heavy ions: (SPS) RHIC, LHC
• fluctuations in financial returns
• natural catastrophes (earthquakes, etc.)
• fractal phase space filling
• network behavior
• some noisy electronics
• near Bose condensates
• citation of scientific papers….

Abstract thermodynamics• S(E) = max (Jaynes-) principle
• nontrivial composition of e.g. the energy E
• 0-th law requires: factorizing form
T1(E1) = T2(E2)
• This is equivalent to the existence and use of an
additive function of energy L(E)!
• Repeated compositions asymptotically lead to
such a form! ( formal logarithm )
• Enrtopy formulas and canonical distributions

Summary
• Thermodynamics build on composition laws
• Deformed entropy formulas
• Hawking entropy: phase space of f ( r ) = 0: horizon ‘size’
• Schwarzschild BH: Boltzmann entropy unstable eos
• Rényi entropy: stable BH eos at high energy ( T > Tmin )
• Estimate for q: from the instability being in the Trans-
Planckian domain
