Diagonalization of Hamiltonians, uncertainty matrices and Robertson inequality
D. A. Trifonov
The problem of diagonalization of Hamiltonians of N-dimensional boson systems by means of time-dependent canonical transformations (CT) is considered, the case of quadratic Hamilto…

Polarized distances between quantum states and observables
D. A. Trifonov, S. G. Donev
The proposition 1 is incomplete. In some of the examples D(a,b) may not obey the triangle inequality. The paper is withdrawn for further elaboration.

Generalized intelligent states and SU(1,1) and SU(2) squeezing
D. A. Trifonov
A sufficient condition for a state |ψ> to minimize the Robertson-Schrödinger uncertainty relation for two observables A and B is obtained which for A with no discrete spectrum is a…
