Rough setSummary: In this paper, we intend to study a connection between rough sets and lattice theory. We introduce the concepts of upper and lower rough ideals (filters) in a lattice. Then, we offer some of their properties with regard to prime ideals (filters), the set of all fixed ...

the sublattice symmetry falls into class I, as demonstrated by the Su–Schrieffer–Heeger (SSH) model in Fig.1a15. Otherwise, it falls into class II, where the 1D model with uniform nearest

basis set convergence (BSCE) and superposition (BSSE) errors. Let us take dimer of two moleculesAandB. Using the counterpoise theory, the uncorrected (\(\Delta {E}_{AB}^{{\rm{raw}}}\)) and corrected (\(\Delta {E}_{AB}^{{\rm{CP}}}\)) energies are calculated in the following ...
Compression of a magnetic material leads to a change in its magnetic properties. We examine this effect using spin-lattice dynamics for the special case of bcc-Fe, using both single- and poly-crystalline Fe and a bicontinuous nanofoam structure. We find
