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

When working with operators in second quantization, I always imagine

[tex]

c^\dagger_ic_j

[/tex]

as denoting the "good old" matrix element [itex]\left\langle {i}

\mathrel{\left | {\vphantom {i j}}

\right. \kern-\nulldelimiterspace}

{j} \right\rangle [/itex]. But how should I interpret an operator given by e.g.

[tex]

c^\dagger_ic_j^\dagger?

[/tex]
