In the tutorials, we see that MgB2 has a well separated superconducting gaps in both delta vs T plot and quasiparticle density of state plot. However, in case of NbSe2 (S. Das et. al. npj Computational Materials (2023) 66) and MoTe2 (Hari Paudyal et. al. PHYSICAL REVIEW B 101, 214515 (2020)) , the ...

Dear Hari sir and Shashi sir, Thank you for your kind reply. In deed, I have got a reasonably matching electron and phonon bandstructure from QE and EPW and the spread is less than 5 ang. 1. However, my Maximum Im/Re Ratio is sometimes greater than 100. Is that a problem ? 2. My maximum phonon ...

Dear EPW experts, I'm relatively new to using EPW. I need to do superconductivity calculation using Eliashberg equations and I have following queries. Kindly forgive me if these questions are basic and already been answered. I tried but couldn't locate the answers for these in the forum. I have ...
