Hello everyone, I m currently working on a problem that is freaking me out a bit, suppose I have a second quantized hamiltonian:
\begin{eqnarray}
H=H_{0}+ \epsilon d^{\dagger}d + V(d{\dagger}c_{0} + h.c)
\end{eqnarray}
In terms of some new operators, I would like to rotate the hamiltonian, so that one part of it is diagonalised in the new operators, how can I do this¿ And compute the matrix elements
