Plan for the ICTP 2020 school tutorials

Setting up the Yambo Quantum Machine

The tutorials will be run on a dedicated Quantum Machine. This is run by installing it as Virtual Machine with the VirtualBox program.

  • VirtualBox is installed on your PC. To find it open a terminal and
>which virtualbox
/usr/bin/virtualbox
  • The Yambo Quantum Machine image (.ova file) is already in the /scratch
>cd /scratch
>/scratch$ ls
(...) YAMBO_Quantum_Mobile.ova

Now follow exactly the instructions to


Monday 27 Jan HANDS-ON 1

14:40 - 17:00 From the DFT ground state to the complete setup of a Many Body calculation using Yambo Davide Sangalli (CNR-ISM, Italy), Pedro Melo (University of Liege, Belgium)

Tuesday 28 Jan HANDS-ON 2

14:00 - 18:00 A complete tour through GW simulation in a complex material (from the blackboard to numerical computation: convergence, algorithms, parallel usage) Daniele Varsano (CNR-NANO, Italy), Andrea Ferretti (CNR-NANO, Italy)

16:30 - 18:00 A complete tour through GW simulation in a complex material (from the blackboard to the computer settings: convergence, algorithms, parallel usage) (continued) Daniele Varsano (CNR-NANO, Italy), Andrea Ferretti (CNR-NANO, Italy)

  • Parallel GW: strategies for running Yambo in parallel
  • GW convergence: use Yambo in parallel to converge a GW calculation for a layer of hBN (hBN-2D)
