EPW Forum

hello Hyungjun Lee : PS) The number of excluded bands also affects the number of electrons in EPW which is used in the evaluation of the Fermi energy in EPW. But, in your 2nd example, you specified the Fermi energy and in this case the number of electrons (the variable of nelec in EPW) is not consid...

Hi Hari Paudyal : I am glad to receive your reply to me. But I still have my doubts. According to your answer: Yes, use "efermi_read = .true." and "fermi_energy = XXX" (XXX: value of the Fermi energy you want to use in eV) two flags in your input file. but the a2f output calculated by EPW after I sp...

Hello administrator: I encountered a problem when I used EPW to calculate the electro-acoustic coupling strength. The output file will output a Fermi level after the epw.x calculation, but the Fermi level in Self consistent calculation is quite different from the epw.x output. The Self-consistent ou...

Hi. Thank you very much for your answer. I used QE6.6 version, which was also used in calculation of other systems before, so I have never used this parameter. I will try this parameter is also available in QE6.6 version.

Hello administrator: Recently,i had a problem with Solve Anisotropic Eliashberg Equations, where no error file was reported after an interrupt to the calculation process and got stuck in the output line below. What could be the problem? Pade approximant of anisotropic Eliashberg equations from imagi...

Hello , Hari Paudyal, First of all, thanks for your help! I'd like to ask you one more question. The question is : Does the machine memory you indicate here calculate the machine's stored memory ? Or can I understand that this memory can be resolved by setting the parameter 'max_memlt'? Best wish, d...

Hello : I had a problem with Solve Anisotropic Eliashberg Equations, where no error file was reported after an interrupt to the calculation process and got stuck in the output line below. What could be the problem? The last lines of the output file: Read from file delta and znorm on imaginary-axis T...
