On the diagonalization of quadratic Hamiltonians
Ville J. Härkönen, Ivan A. Gonoskov
A new procedure to diagonalize quadratic Hamiltonians is introduced. We show that one can find a unitary transformation such that the transformed quadratic Hamiltonian is diagonal…

Light-matter quantum dynamics of complex laser-driven systems
Ivan Gonoskov, Stefanie Gräfe
We propose a novel general approximation to transform and simplify the description of a complex fully-quantized system describing the interacting light and matter. The method has s…
