Towards the unified non-classical physics: account for quantum fluctuations in equilibrium thermodynamics via the effective temperature
The concept of effective temperature (ET) T*(T₀, T ) is used in order to approximately “quantize” the thermodynamic functions of the dynamical object which is in the thermal equilibrium with thermal bath being at constant temperature T (T₀ = E₀/kB, where E₀ is the ground-state energy, kB – Boltz...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The concept of effective temperature (ET) T*(T₀, T ) is used in order to
approximately “quantize” the thermodynamic functions of the dynamical
object which is in the thermal equilibrium with thermal bath being at constant
temperature T (T₀ = E₀/kB, where E₀ is the ground-state energy,
kB – Boltzmann constant, is the characteristic “quantum” temperature of
the system itself). On these grounds the extensive comparative investigation
is carried out for the “standard model” of statistical mechanics – the
one-dimensional harmonic oscillator (HO). Three well-known approaches
are considered and their thermodynamic consequences thoroughly studied.
These are: the exact quantum, or non-classical Planck-Einstein approach,
intermediate, or semiclassical Bloch-Wigner approach and, finally,
the pure classical, or Maxwell-Boltzmann approach. |
