This is the homepage for the hands-on tutorial Laboratory of Quantum Simulation of Materials (LabQSM), a university (master-level) class on electronic structure methods, with a particular focus on density functional theory (DFT).

Starting from 2016/2017, this training material has been extensively used in Master degree in Physics of the University of Modena and Reggio Emilia (UniMoRe), fall terms.

Authors and credits: Andrea Ferretti and Daniele Varsano

 == Getting Started ==
-In order to go through this tutorial you need to have access to a Unix/Linux machine, where you can run Unix terminals.
+=== Machine setup and Training material ===
-Software-wise, one needs the following:
+* [[Getting Started#Machine setup| Machine setup]]
-* One '''quantum engine''', i.e. a software able to run quantum mechanical DFT simulations. Here we consider [http://www.quantum-espresso.org Quantum ESPRESSO] (QE). During this class we'll be using QE-v6.5, though any version newer that 6.0 would do.
+* [[Getting Started#Training material| Training material]]
-* '''Structure visualization and builders''': applications like [http://www.xcrysden.org XcrySDen] (QE compatible structure visualization) and [https://avogadro.cc Avogadro] (molecular editor) will be used in the more advanced part of the class.
-* General purpose '''scientific plotting tools'''. At least one of the following SW should be available: [https://plasma-gate.weizmann.ac.il/Grace/ (XM)Grace], [http://www.gnuplot.info Gnuplot], or python with [https://matplotlib.org matplotlib] support.
-Several options are available:
-* (A) exploit the '''Quantum Mobile''' virtual machine (VM);
-* (B) connect to existing machines, compliant with the class, as provided by the tutors
-* (C) install your own machine
-=== Using Quantum Mobile ===
-Quantum mobile is a ready-to-go VM, thought to provide all MaX flagship codes (incl QE) together with AiiDA seamlessly integrated in a plug-and-play linux (Ubuntu) environment. Quantum Mobile is [https://www.materialscloud.org/work/quantum-mobile available] on the [https://www.materialscloud.org MaterialsCloud] portal.
+== Link to Selected Laboratories ==
-Step by step installation:
+=== Module 0: The Unix environment (3h)===
-* Download the latest version of Quantum Mobile, following the link here: [https://github.com/marvel-nccr/quantum-mobile/wiki https://github.com/marvel-nccr/quantum-mobile/wiki]. By doing this you'll obtain a VM image.
+* [[Warming up with Unix commands]]
-* If not available, install [https://www.virtualbox.org VirtualBox] to run the Quantum Mobile VM.
+* [[Scripting]]
-* Double click on the Quantum Mobile to start the VM.
+* [[Plotting and visualization tools]]
-* At this point, you should see a virtualised Ubuntu OS. By opening a terminal you'll see that pw.x (and the other required executables) are available. Among others, all executables from the QE distribution, XcrySDen, Grace, gnuplot, and python are all pre-installed.
-* Further information about Quantum Mobile installation can be found here: [https://github.com/marvel-nccr/quantum-mobile/releases/ https://github.com/marvel-nccr/quantum-mobile/releases/].
-=== Connecting to existing machines ===
+=== Module 1: Basic DFT calculations and Convergences (9h) ===
+* [[Structural and electronic properties of semiconductors and metals]]
+* [[Non self-consistent calculations: Band structures and Density Of States]]
-=== Install your own machine ===
+=== Module 2: DFT simulations of Molecules (6h) ===
+*[[Electronic properties of isolated molecules]]
-If you want to use your desktop or laptop, be sure you have the following software installed:
+=== Module 3: Low dimensional structures (6h) ===
-One quantum engine, i.e. a software able to run quantum mechanical DFT simulations. Here we consider Quantum ESPRESSO (QE). During this class we'll be using QE-v6.5, though any version newer that 6.0 would do.
+*[[Electronic properties of 2D and 1D systems]]
-Structure visualization and builders: applications like XcrySDen (QE compatible structure visualization) and Avogadro (molecular editor) will be used in the more advanced part of the class.
-General purpose scientific plotting tools. At least one of the following SW should be available: (XM)Grace, Gnuplot, or python with matplotlib support.
