Two energy scales and slow crossover in YbAl3.
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...
متن کاملQuintessence with two energy scales
We study quintessence models using low energy supergravity inspired from string theory. We consider effective supergravity with two scales mS , the string scale, and mPl , the Planck scale, and show that quintessence naturally arises from a supersymmetry breaking hidden sector. As long as supersymmetry is broken by the F-term of a Polonyi-like field coupled to the quintessence field in the Kähl...
متن کاملFickian crossover and length scales from two point functions in supercooled liquids.
Particle motion of a Lennard-Jones supercooled liquid near the glass transition is studied by molecular dynamics simulations. We analyze the wave vector dependence of relaxation times in the incoherent self-scattering function and show that at least three different regimes can be identified and its scaling properties determined. The transition from one regime to another happens at characteristi...
متن کاملSlow Crossover in YbXCu4 Intermediate Valence Compounds
We compare the results of measurements of the magnetic susceptibility χ(T ), the linear coefficient of specific heat γ(T ) = C(T )/T and 4f occupation number nf (T ) for the intermediate valence compounds YbXCu4 (X = Ag, Cd, In, Mg, Tl, Zn) to the predictions of the Anderson impurity model, calculated in the non-crossing approximation (NCA). The crossover from the low temperature Fermi liquid s...
متن کاملSlow crossover to Kardar-Parisi-Zhang scaling.
The Kardar-Parisi-Zhang (KPZ) equation is accepted as a generic description of interfacial growth. In several recent studies, however, values of the roughness exponent alpha have been reported that are significantly less than that associated with the KPZ equation. A feature common to these studies is the presence of holes (bubbles and overhangs) in the bulk and an interface that is smeared out....
