Let λ<sub>1</sub>, λ<sub>2</sub>, . . . , λ<sub>n </sub>be eigenvalues of graph G, then the energy of G is defined as E (G) =∑<sup>n</sup><sub>n=1</sub>|λ<sub>ه</sub>|. The aim of this paper is to compute the eigenvalues of two fullerene graphs C<sub>60</sub> and C<sub>80</sub>. eigenvalue fullerene graph energy https://jdma.sru.ac.ir/article_499_691393c2d9995d0fdd22702ef88487f1.pdf

This film is considered as a two-dimensional electron gas which is under the influence of a uniform external magnetic field B and a uniform external electric field E. Here, the magnetic field is perpendicular to the film. Also, in this paper, we have selected the Landau gauge, because this gauge is useful for working in rectangular geometries. thin film landau gauge energy levels wavefunctions https://jdma.sru.ac.ir/article_515_6d449812e2cc277ff8ace89d01f4dbcb.pdf
