I'm running a simple limiting case of a simulation with the expression:(adsbygoogle = window.adsbygoogle || []).push({});

exp(-i*H*t), where H is the hamiltonian, in this case a 2x2 matrix of zeros. Should this evaluate to 0, or to [ 1 1 ; 1 1] ?

Right now my sim uses the latter, which I'm sure is wrong. What do you think? Thanks in advance.
