Quantum time delay for unitary operators: general theory

Diomba Sambou, Rafael Tiedra de Aldecoa

We present a suitable framework for the definition of quantum time delay in terms of sojourn times for unitary operators in a two-Hilbert spaces setting. We prove that this time de…

On the spectral properties of non-selfadjoint discrete Schrödinger operators

Olivier Bourget, Diomba Sambou, Amal Taarabt

Let be a purely absolutely continuous selfadjoint operator acting on some separable infinite-dimensional Hilbert space and be a compact non-selfadjoint perturbation. We r…
