Looking for a command for this calligraphic phi

enter image description here

(\varphi is not the same and \mathcal{\varphi} does not work).

Solutions working under mathjax are more preferred.

  • This is an L, not a phi. Indeed \mathscr{L} also works with MathJax.

This also works in MathJax: $\mathscr{L}$
