lorentzian broadening with gamma? What are the drude terms? Is the scissors

If possible, could you please recommend some papers because there are no
contents about them in userguide and paper by Prof. Ambrosch? I am a new one to
optic calculation. Thank you for your patience!<o:p></o:p></span></font></p>
