Quasi-particle properties

UNDER CONSTRUCTION (DV)

In this tutorial you will learn how to:

• calculate quasi-particle correction in HF approximation
• calculate quasi-particle correction in GW approximation
• How to choose the input parameter for a meaningful converged calculation
• How to plot a band structure including quasi-particle corrections

Prerequisites

• Complete the Generating the Yambo databases tutorial
• SAVE folder for bulk hBN.
• yambo executable
• ypp executable
• Run Initialization

The HF approximation (yambo -x)

As you have seen in the lectures the GW self-energy is separated in two components named exchange self-energy (| Final Sigma || ς || S, S2, J) and correlation self-energy (*Sc).
