Cover Story: The intriguing strange metal behavior, characterized by a linear dependence of the electrical resistivity on the temperature, is observed in a variety of systems and remains an unsolved mystery. In the last years, we were led to attribute this behavior to the scattering of electrons on slow bosons. Recent resonant x-ray scattering experiments on cuprates unambiguously detected a good candidate for the slow boson in the form of dynamical short-ranged charge density fluctuations. To extend the strange metal behavior down to very low temperature, the characteristic relaxation time of these fluctuations must grow large, and in this work we propose a possible mechanism that triggers this growth, due to the interplay of charge density fluctuations and long-wavelength diffusive charge collective modes.

The intuitionistic hesitant fuzzy set (IHFS) is an enriched version of hesitant fuzzy sets (HFSs) that can cover both fuzzy sets (FSs) and intuitionistic fuzzy sets (IFSs). By assigning membership and non-membership grades as subsets of [0, 1], the I...

In this paper, we consider the asymptotic behavior (as t→∞) of solutions as an initial boundary value problem for a second-order hyperbolic equation with periodic coefficients on the semi-axis (x>0). The main approach to studying the problem under...

It has been found that the topology effect and the possible emergent hidden scale and hidden local flavor symmetries at high density reveal a novel structure of compact star matter. When Nf≥2, baryons can be described by skyrmions when the number...
