Most energetic passive states.
Passive states are defined as those states that do not allow for work extraction in a cyclic (unitary) process. Within the set of passive states, thermal states are the most stable ones: they maximize the entropy for a given energy, and similarly they minimize the energy for a given entropy. Here we find the passive states lying in the other extreme, i.e., those that maximize the energy for a g...
متن کاملEnergetic Charged Particles Above Thunderclouds
The French government has committed to launch the satellite TARANIS to study transient coupling processes between the Earth’s atmo sphere and near-Earth space. The prime objective of TARANIS is to detect energetic charged particles and hard radiation emanating from thunderclouds. The British Nobel prize winner C.T.R. Wilson predicted lightning discharges from the top of thunderclouds into spac...
متن کاملSolar flares and energetic particles.
Solar flares are now observed at all wavelengths from γ-rays to decametre radio waves. They are commonly associated with efficient production of energetic particles at all energies. These particles play a major role in the active Sun because they contain a large amount of the energy released during flares. Energetic electrons and ions interact with the solar atmosphere and produce high-energy X...
متن کامل/ 00 01 32 8 v 1 3 1 Ja n 20 00 THE MOST ENERGETIC PARTICLES IN THE UNIVERSE
Several issues related to the lensing of ultra-high energy cosmic rays by the Galactic magnetic field are discussed. The spectrum of the cosmic rays (CRs) arriving to the Earth has the overall shape of a leg, with a knee at 10 16 eV beyond which it becomes steeper and an ankle at ∼ 5×10 18 eV where it becomes harder again up to the highest energies observed of 3 × 10 20 eV. The region beyond th...
متن کاملThe Unpredictability of the Most Energetic Solar Events
Observations over the past two solar cycles show a highly irregular pattern of occurrence for major solar flares, γ-ray events, and solar energetic particle (SEP) fluences. Such phenomena do not appear to follow the direct indices of solar magnetic activity, such as the sunspot number. I show that this results from non-Poisson occurrence for the most energetic events. This Letter also points ou...
