Orthogonal Quantum Krylov Diagonalisation
Hadi Rammal, Alexandre Perrin, Oumaya Ladhari +3
Quantum subspace-diagonalization methods, particularly Quantum Krylov Diagonalization (QKD), provide a promising route for computing low-energy spectra of quantum many-body Hamilto…

Tunable anharmonicity in cavity optomechanics in the unresolved sideband regime
Jonathan L. Wise, Clement Dutreix, Fabio Pistolesi
Introducing a controlled and strong anharmonicity in mechanical systems is a present challenge of nanomechanics. In cavity optomechanics a mechanical oscillator may be made anharmo…

Two-Level System Nanomechanics in the Blue-Detuned Regime
Guillaume Bertel, Clement Dutreix, Fabio Pistolesi
We study a mechanical oscillator coupled to a two-level system driven by a blue-detuned coherent source in the resolved sideband regime. For weak mechanical damping, we find dynami…
