Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

This should be very simple...

If I have a state <1|AB|2> where A and B are Hermitian operators, can I rewrite this as <2|BA|1> ?

That would be, taking the complex conjugate of the matrix element and saying that A*=A and B*=B.

Thank you!
