Experimental results for the susceptibility, magnetization, specific heat, 4f occupation number, Hall effect, and magnetoresistance for single crystals of the intermediate valence (IV) compound YbAl3 show that, in addition to the Kondo temperature scale T(K) approximately 670 K, there is a low temperature scale T(coh) approximately 30-40 K for the onset of Fermi liquid coherence. Furthermore, t...
we study the eigenenergies and eigenfunctions of the ground and first excited states (gfes) of an electron strongly coupled to the lo-phonon in an asymmetry quantum dot (aqd) under an applied electric field by using a variational method of the pekar type (vmpt). this aqd two-level system may be viewed as a single qubit. when the electron is in the superposition state (ss) of the gfes, the effec...
We consider the analytical investigation of the heat current in the steady state of the quantum harmonic chain of oscillators with alternate masses and self-consistent reservoirs. We analyze the thermal conductivity kappa and obtain interesting properties: in the high temperature regime, where quantum and classical descriptions coincide, kappa does not change with temperature, but it is quite s...
We pursue our investigation of the non-equilibrium dynamics of the Backgammon model, a dynamical urn model which exhibits aging and glassy behavior at low temperature. We present an analytical study of the scaling behavior of the local correlation and response functions of the density fluctuations of the model, and of the associated fluctuation-dissipation ratios, throughout the α-regime of low...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Abstract In this paper, we present results from spontaneous ignition of aluminium particle clouds in a series shock tube experiments. For all experiments, the propagates along narrow pile 40- $$\upmu $$ μ m particles. The study includes Mach numbers range 1.51 to 2.38. are visualised using photographic techni...
We prove that in the high temperature regime (T/J > 1) the deviation of the total free energy of the Sherrington-Kirkpatrick (S-K) spin glass model from the easily computed logAv(ZN({βJ})) converges in distribution, as ΛΓ-KX), to a (shifted) Gaussian variable. Some weak results about the low temperature regime are also obtained.
