![]() In the effective temperature given above, the temperature is used to construct an effective classical model. The Thomas–Fermi wavevector (in Gaussian-cgs units) is \displaystyle, which has a maximum relative error of < 2.3%. It is named after Llewellyn Thomas and Enrico Fermi. I got quite confused with the math in Thomas-Fermis approximation. 1 It is named after Llewellyn Thomas and Enrico Fermi. It is a special case of the more general Lindhard theory in particular, Thomas–Fermi screening is the limit of the Lindhard formula when the wavevector (the reciprocal of the length-scale of interest) is much smaller than the fermi wavevector, i.e. It is a special case of the more general Lindhard theory in particular, ThomasFermi screening is the limit of the Lindhard formula when the wavevector (the reciprocal of the length-scale of interest) is much smaller than the fermi wavevector, i.e. Thomas–Fermi screening is a theoretical approach to calculate the effects of electric field screening by electrons in a solid.
