Statistical diagonalization of a random biased Hamiltonian: the case of the eigenvectors
Grégoire Ithier, Saeed Ascroft
We present a non perturbative calculation technique providing the mixed moments of the overlaps between the eigenvectors of two large quantum Hamiltonians: and $\hat{H}…

Typical equilibrium state of an embedded quantum system
Grégoire Ithier, Saeed Ascroft, Florent Benaych-Georges
We consider an arbitrary quantum system coupled non perturbatively to a large arbitrary and fully quantum environment. In [G. Ithier and F. Benaych-Georges, Phys. Rev. A 96, 012108…
