It is well known that non-ideal magnetohydrodynamic effects are important in the dynamics of molecular clouds: both ambipolar diffusion and possibly the Hall effect have been identified as significant. We present the results of a suite of simulations with a resolution of 512 of turbulent decay in molecular clouds incorporating a simplified form of both ambipolar diffusion and the Hall effect si...

In today’s world, no one can deny the expansion of economic influence in the various aspects of social life and economization of immaterial issues of social life is becoming more obvious every day. The valuation of cultural goods, as one of the most important economic aspects related to arts and culture, is chosen to be considered in this study. The necessity of considering the economic valuat...

We have proposed a unified framework towards the dynamics of optical and electron vortex beams from the perspective of the geometric phase and the associated Hall effects. The unification is attributed to the notion that the spin degrees of freedom of a relativistic particle, either massive or massless, are associated with a vortex line. Based on a cylindrical coordinate formulation, which lead...

We analyze the effects of long-range Coulomb interaction on distribution Berry curvature among bands near charge neutrality twisted bilayer graphene (TBG) closely aligned with hexagonal boron nitride (hBN). Due to suppressed dispersion narrow bands, band structure is strongly renormalized by electron-electron interactions, and thus, associated topological properties are sensitive filling. Using...
