Contribution and History ========================= This work was supported in part by Prof. J.A. Szpunar grant from the National Sciences and Engineering Research Council of Canada, Sylvia Fedoruk Canadian Centre for Nuclear Innovation and Innovation Saskatchewan, the University of Saskatchewan, and the Department of Computational Material Science of the Institute of Nuclear Physics, PAN, Cracow, Poland. The access to high performance supercomputers provided by Compute Canada(CLUMEQ and Westgrid) and plato.usask.ca is acknowledged. The provided here tutorials are for Unix environment and limited scope and we will be happy to add any material (especially on other platform like windows), which is concerned with similar or related tasks for Quantum Espresso code. We would like to thanks the students from the University of Saskatchewan, especially Ravi Kiran and Linu Malakkal for help to improve this web page and debug it. Here is the list of early tutorials developed at the University of Saskatchewan and listed by Dr. P. Jochym on his account as indicated. Note that these tutorials restrict usage of QE code as detected by Ravi and Linu and therefore new applications are being developed. The comment about fixing some restrictions is posted on http://homepage.usask.ca/~bas627/nipy/Nipy.htm. * [Crystal structure](http://nbviewer.ipython.org/gist/jochym/603c0d13bc7d3dc8148d) - introduces the basic ideas of the system and presents a set of basic static calculations. * [Remote execution](http://nbviewer.ipython.org/gist/jochym/d504ce067b99686e4ae8) - shows how to set-up the remote execution of the Qeuantum Espresso over the network (e.g. in some supercomputing center). * [Electronic structure] [http://nbviewer.ipython.org/gist/jochym/99f18778525832746d48]- shows band structure and density of states of elrctrons * [Primitive unit cells](http://nbviewer.ipython.org/gist/jochym/d68d81026eed03467d69) - demonstrates the concept of the primitive unit cell and shows a way the system deals with them. * [Structure optimization](http://nbviewer.ipython.org/gist/jochym/f7b46f20640f3e2e7634) - shows how to find minimum of energy of the system with more degrees of freedom (low symmetry structures etc.). The example of structure minimization for a simple structure is included in the first tutorial. * [Elastic constants](http://nbviewer.ipython.org/gist/jochym/5fb472070a272b61f75c) - introduces the Elastic package and shows the calculation of elastic constants using this tool. * [Lattice dynamics](http://nbviewer.ipython.org/gist/jochym/f3f37daa4cf1884f02ad) - shows the use of DFPT module in Quantum Espresso for calculation of vibration modes in the crystal as well as use of utility functions in the QE-util for easier analysis of the obtained data. * [Quasi-Harmonic Approximation](http://nbviewer.ipython.org/gist/jochym/334b658cc8b3f6864c23) - explains the procedure of calculating temperature-dependent behaviour in the framework of the QHA using the tools provided within the QE-util package. http://www.barbara-research.ca/nipy/Nipy.htm shows the new updated version by Linu Malakkal
