Quantum Espresso Series: How to run calculations in Quantum Espresso

I found a blog where nuts and bolts of doing calculations in Quantum Espresso code. In the blog post from quantumbarista.blogspot.com , the author Ryan Cloke has discussed the "Electronic Structure Calculations of Graphene Nanoribbons Using Quantum Espresso".

This blog post provides a detailed description on how to compute the band structure of a graphene nanoribbon.

Have a look at it.

I will do calculations and update to you later.


Quantum Espresso Series: Installing Quantum Espresso in Ubuntu 16.04 for newbies

Quantum Espresso is a opensource code for studying the electronic properties of materials. Installation of Quantum Espresso had been a difficult task earlier for new comers (now I believe that it is easy)
