In subject area: Physics and Astronomy Thermal radiation refers to the mode of heat transfer that occurs in various practical scenarios such as power plants, combustion chambers, and heat exchangers. It involves the transfer of energy through electromagnetic waves emitted by objects due to their temp...

large value of the propagonic contribution to the thermal conductivity: in fact, with ωP/2π = 3 THz, κP constitutes about 60% of the thermal conductivity at room temperature, a fraction that inevitably grows for lower temperatures, due to the increasing importance of low-energy ...
A thermodynamic potential in local thermal equilibrium, or the so-called Masseiu-Planck functional, is identified as a generating functional for conserved currents such as the energy-momentum tensor and the electric current. 展开 关键词: Finite temperature field theory Path integrals Quantum fields in...

Phonon polaritons are promising for infrared applications due to a strong light-matter coupling and subwavelength energy confinement they offer. Yet, the spectral narrowness of the phonon bands and difficulty to tune the phonon polariton properties hinder further progress in this field. SrTiO3– a pro...
We propose empirical formulae of the electrical conductivity sigma and thermal conductivity for elemental metals such as Na, Cu or Fe at room temperature ranges. Assuming the relaxation time is given by the Planck constant divided by pai and further divided by the thermal energy kT for all ...
High-energy elastic backscattering of helium ions for compositional analysis of high-temperature superconductor thin films A thin‐film technique for measuring the chemical composition of Y‐Ba‐Cu‐O thin films to a few percent accuracy is described. This technique utilizes no... JA Martin,M ...
Thermal energy atomic collisions of the typeA(2P3/2)+B(1S0) are discussed to clarify the dependence of the orientational anisotropy in the total cross section on the relative velocityv. Simple expressions for / are derived by semiclassical treatments designed to be appropriate for large spin-orb...
