One has unusual phenomena in solids largely contributed by the behavior of the electron. One could have instances where on a lattice of notionally equivalent atoms, the electron is found to favour some atoms over others. Alternately, one could have instances where an orbital is favoured over seemingly equivalent ones. I will start by an introduction to what tells the electron what to do. This gives us the tools to look into the mind of the electron and so we know what to expect when we bring different atoms together to form solids. Starting with examples which confirm with the rules, I will go on to examples which are the law-breakers, taking examples from our research, which is part of the excitement in the study of condensed matter systems.

ABOUT DR LAKSHMI RAMAN (1947-2014):
Dr Lakshmi Raman was eduacated at Lady Sivaswamy Iyer Girl’s high school, Mylapore and Queen Mary’s college, Chennai, before undertaking a PhD in crystal dynamics in the Dept. of Physics, IITM. She did post-doctoral research at MPI, Stuttgart, ETH, Zurich and the University of Texas, Austin. Dr Raman then moved to the private sector. She had a long association with BellCore (a.k.a. Bell Labs) where she worked in the sphere of telecommunications particularly in the area of network management. She was an internationally recognized expert regarding standards in telecommunication. She was the author and coauthor of books and network management. Throughout her life she had a keen interest in the higher education of women and volunteer teaching of high-school students.
