Temperature measurements using planar laser-induced fluorescence (PLIF) are most often associated with experimental challenges. In addition, no PLIF technique is generally applicable in all kinds of environment. Especially under sooting conditions problems are prone to arise, which limits the use of these techniques. In this paper the two-line atomic fluorescence (TLAF) technique was investigat...
We analyze temperature and thermometry for simple nonequilibrium heat-conducting models. We also show in detail, for both twoand three-dimensional systems, that the ideal-gas thermometer corresponds to the concept of a local instantaneous mechanical kinetic temperature. For the 4 models investigated here the mechanical temperature closely approximates the local thermodynamic equilibrium tempera...
The rapidly developing quantum technologies and thermodynamics have put forward a requirement to precisely control measure the temperature of microscopic matter at level. Many thermometry schemes been proposed. However, measuring low is still challenging because obtained sensing errors generally tend diverge with decreasing temperature. Using continuous-variable system as thermometer, we propos...
The working principle of a new kind of nanothermometer is experimentally demonstrated using bistable materials with thermal memory. This thermometry approach allows for acquiring sub-wavelength resolution images of fast, transient heating events.
We compare strategies for evaporative and sympathetic cooling of two-species Fermi-Bose mixtures in single-color and two-color optical dipole traps. We show that in the latter case a large heat capacity of the bosonic species can be maintained during the entire cooling process. This could allow one to efficiently achieve a deep Fermi degeneracy regime having at the same time a significant therm...
