Abstract: The lattice dynamics in magnetic materials, such as Fe depends on the degree of disorder of the atomic magnetic moments and the time scale of spin fluctuations. Using first-principles methods, we have studied this effect… read more here.

Abstract: Scalar fields, ${\ensuremath{\phi}}_{i}$, can be coupled nonminimally to curvature and satisfy the general criteria: (i) the theory has no mass input parameters, including ${M}_{P}=0$; (ii) the ${\ensuremath{\phi}}_{i}$ have arbitrary values and gradients, but undergo a… read more here.

DOI: 10.1103/physrevd.96.074027
Abstract: The strong decays of the two resonances $\ensuremath{\eta}(2225)$ and $\ensuremath{\phi}(2170)$ are discussed for selected decay channels. The two resonances are considered as the $\mathrm{\ensuremath{\Lambda}}\overline{\mathrm{\ensuremath{\Lambda}}}$ bound states in the molecular scenario. The phenomenological hadronic molecular approach… read more here.
