<div dir="ltr">Dear WIEN2k users,<div><br></div><div>I'm wondering what are the units for the dipole matrix elements in mommat2 file calculated from optic program.</div><div><br></div><div>The manual states specifically about the overall units in WIEN2k:</div>"Rydberg atomic units are used except internally in the atomic-like programs (LSTART and LCORE) or in subroutine outwin (LAPW1, LAPW2), where Hartree units are used. The output is always given in Rydberg units "<div><br></div><div><br></div><div>But it seems to me that the dipole matrix elements are in Hartree units. Could you verify the units convention in the mommat2 file?</div><div><br></div><div>Thanks.</div><div>Best,</div><div>Mengxi </div>
