Finite-dimensional Lie algebras in bosonic quantum dynamics: The single-mode case
Tim Heib, Andreea Silvia Goia, Sona Baghiyan +2
We study, classify, and explore the mathematical properties of finite-dimensional Lie algebras occurring in the quantum dynamics of single-mode and self-interacting bosonic systems…

Bounding the rotating wave approximation for coupled harmonic oscillators
Tim Heib, Paul Lageyre, Alessandro Ferreri +5
In this work we study the validity of the rotating wave approximation of an ideal system composed of two harmonic oscillators evolving with a quadratic Hamiltonian and arbitrarily…
