Line shapes in the presence of nonlinear wave collapse in a plasma

Review of recent advances in the analytical theory of Stark broadening of spectral lines in plasmas: applications to laboratory discharges and astrophysical plasmas

“…This effect was first [15]. Despite both the analytical theory of the broadening of ANY H/D line by non-quasimonochromatic Langmuir waves and the observation of this effect were achieved already in 1970s, in several recent publications their authors tried to "re-invent the wheel" [16][17][18][19][20]. Of course, these simulations of selected H/D line did not discover anything new compared to the analytical theory from 1970s, The authors of those simulations seem to be totally unaware of both the corresponding analytical theory and the observation of this effect from 1970s by Sholin's group: they did not make any reference -just as in paper [21], the authors did not refer to about half-a-hundred theoretical and experimental studies of lineshape-based diagnostics of plasma turbulence in laboratory and astrophysical plasmas published between 1970 and (including) 2017, despite this was the subject of paper [21].…”
