Yambo Community Forum

Dear Sir/Madam,
While calculating the quasiparticle band structure at finite temperatures, I noticed that the tutorial on this website ( https://wiki.yambo-code.eu/wiki/index.p ... n_Coupling ) only includes the temperature-dependent evolution of the quasiparticle band gap, but not the full band structure across the entire Brillouin zone at specific temperatures (e.g., 300 K).

My question is: Is the fitted finite-temperature band structure physically meaningful, or just the finite-temperature band gap?

Thank you in advance for your time and expertise.
Best regards,
Yang

Dear Yang,

apologize for the late reply, in the last month we had issues with the forum website that have been solved only now.

I'm not an expert on el-ph calculation, anyway from my understanding they are meaningful. Others developers/users expert in the topic can confirm this in case there are details in the implementation I do ignore.

Best,
Daniele
