The Hamiltonian is given:(adsbygoogle = window.adsbygoogle || []).push({});

H=Aâ†â + B(â + â†)

where â is annihilation operator and â† is creation operator,

and A and B are constants.

How can I get the eigenenergy of this Hamiltonian?

The given hint is "Use new operator b = câ + d, b† =câ† + d

(c and d are constants, too)

But I can't use that hint properly.
