Time operator for a quantum many-body system with SU(1,1) dynamical symmetry
I. Andric, M. Martinis
The time operator canonically conjugated to the Hamiltonian of interacting particles on the line is constructed using SU(1,1) as a dynamical symmetry. This hidden conformal sym…

Time Operator for a Quantum Singular Oscillator
M. Martinis, V. Mikuta
The problem of existence of a self-adjoint time operator conjugate to a Hamiltonian with SU(1,1) dynamical symmetry is investigated. In the space spanned by the eigenstates of the…
