Hi Taifeng, Since we don't know what the polarons look like a priori before we perform the epw2 calculation, it is not straightforward to manually set the position of the polarons. The default gaussian initialization of the A_nk vector in epw2 calculation is to set the polaron wavefunction at r=(0,0 ...

Hi Qiaolin, The polaron module does not support reading fermi energy from input, and the current implementation will give some silent bugs if you set fermi_energy in the input file. So you should trust the value that you got without setting fermi_energy. This bug will be fixed a near future release ...
