Summary0000904: Math Kerning is lost with multi-letter superscripts and subscripts
DescriptionLuaTeX does not apply Math Kerning on multi-letter superscripts and subscripts.
But Math Kerning should apply here, too.

XeTeX keeps Math Kerning here.
I could not check with MS Word.
Steps To ReproduceIn a font with Math Kerning values, e.g. Cambria Math, compare

$L^T$ and $L^{TU}$

$T_A$ and $T_{AB}$

$T_j$ and $T_{ji}

etc.

Additional InformationTested with
LuaTeX, Version beta-0.76.0-2013061817 (TeX Live 2013) (rev 4627)

and
XeTeX 3.1415926-2.5-0.9999.3-2013061817 (TeX Live 2013)

I've uploaded an illustration of the problem (using Cambria in ConTeXt).

The index "ji" following "T" should start at the same horozontal position as the index "j".
