The paper is focused on the dynamic homogenization of lattice-like materials with lumped mass at nodes to obtain energetically consistent models providing accurate descriptions acoustic behavior discrete system. equation motion Lagrangian one-dimensional lattice transformed according a unitary approach aimed identify equivalent non-local continuum integral-differential and gradient type, latter...

Chalcogenide phase-change materials based random access memory (PCRAM) is one of the leading candidates for development non-volatile and neuro-inspired computing technologies. Recent work shows indium to be an important alloying element PCRAM, while a thorough understanding parent compound InTe, in particular, its amorphous phase, still lacking. In this work, we carry out ab initio simulations ...
