Thermal Evolution of Spin-Polarons
Physical Review Letters, 1995We study the thermodynamics of a single hole in the $U=\ensuremath{\infty}$ Hubbard model using a Monte Carlo method which samples graphs that contribute to the partition function; there are no finite-size effects. The heat capacity and magnetic susceptibility indicate a sharp transition between a high temperature spin-polaron and a compact ...

THERMAL SOLUTIONS FOR MOLECULAR EVOLUTION
International Journal of Modern Physics B, 2012The key requirement to solve the origin of life puzzle are disequilibrium conditions. Early molecular evolution cannot be explained by initial high concentrations of energetic chemicals since they would just react towards their chemical equilibrium allowing no further development.

Thermal evolution of flare plasma
Solar Physics, 1983The evolution of hot thermal plasma in solar flares is analyzed by a single-temperature model applied to continuum emission in the 5 keV < E < 13 keV spectral range. The general trend that the thermal plasma observed in soft X-rays is heated by the non-thermal electrons that emit as the hard X-ray bursts is confirmed by the observation of an electron ...

Thermal evolution of the Phlegraean magmatic system
Journal of Volcanology and Geothermal Research, 1999Abstract A series of 2-D conductive/convective numerical models show a rather limited range of possible magma chamber configurations that predict the present thermal regime at Campi Flegrei. These models are calculated by HEAT, which allows continuous adjustment of heterogeneous rock properties, magma injection/replenishment, and convective regimes ...

The thermal environment as a moderator of social evolution
Biological Reviews, 2021ABSTRACTAnimal sociality plays a crucial organisational role in evolution. As a result, understanding the factors that promote the emergence, maintenance, and diversification of animal societies is of great interest to biologists. Climate is among the foremost ecological factors implicated in evolutionary transitions in social organisation, but we are ...

Physics of the Earth and Planetary Interiors, 1984
A modification of the Boussinesq fluid assumption is the basis of the present theory of three-dimensional and finite amplitude convection in a viscous spherical shell with temperature- and pressure-dependent physical parameters. The theory is applied to the definition of thermal evolution models for Venus which emphasize the effects of certain physical

Journal of Thermal Analysis and Calorimetry, 2007
The thermal evolution of a slate rock sample (Berja, Almeria, Spain) has been studied. The phase minerals identified in this sample were mica (illite), chlorite (clinochlore) and quartz as major components, with minor microcline, iron oxide and a mixed-layer or interstratified phase (montmorillonite-chlorite).

Thermal evolution of the earth
Tectonophysics, 1981Abstract Models to study the thermal evolution of the earth have been developed based on a calculation of finite-amplitude thermal convection in an incompressible and viscous mantle with temperature and pressure-dependent physical parameters. The lateral dependences of the variables are resolved through their spherical harmonic representations, while

The Moon, 1972
The thermal history and current state of the lunar interior are investigated using constraints imposed by recent geological and physical data. Theoretical temperature models are computed taking into account different initial conditions, heat sources, differentiation and simulated convection.

Evolution of a Thermal Disturbance
1989The thermodynamic equation for an ideal gas is where ρcv6 is the internal energy per unit volume and hR is the radiative heating rate. For the sake of clarity we omit diabatic terms additional to the radiative heating. We may expand the left-hand side of (10.1) and write it in the form of an enthalpy equation, and cp is the specific heat at constant ...
