Some current topics in condensed matter physics 2018. Selected topics on quantum and photonic structures

For some years, some members of the Group of Solid State Physics at the Morelos Autonomous State University (UAEM), have edited a series of compilations of selected talks that were presented at the Workshop of Molecular and Condensed Matter Physics, which is been held at UAEM since 2008. This is the fifth of this series of electronic books, which corresponds to the compilation made in 2018. It contains some recent contributions in several areas of the research frontier in Condensed Matter Physics (http://web.fc.uaem.mx/ tallerfmcm/temas.htm). Since the first edition we have decided to keep the bilingual format (English-Spanish) with the purpose of achieving a wider diffusion of the contents via electronic means.
