Cross-Kerr nonlinearity in optomechanical systems
R. Khan, F. Massel, T. T. Heikkilä
We consider the response of a nanomechanical resonator interacting with an electromagnetic cavity via a radiation pressure coupling and a cross-Kerr coupling. Using a mean field ap…
Enhancing optomechanical coupling via the Josephson effect
Tero T. Heikkilä, Francesco Massel, Jani Tuorila +2
Cavity optomechanics is showing promise for studying quantum mechanics in large systems. However, smallness of the radiation-pressure coupling is a serious hindrance. Here we show…
Tension-induced non-linearities of flexural modes in nanomechanical resonators
Raphaël Khan, F. Massel, T. T. Heikkilä
We consider the tension-induced non-linearities of mechanical resonators, and derive the Hamiltonian of the flexural modes up to the fourth order in the position operators. This te…
Macroscopic quantum tunneling in nanoelectromechanical systems
Mika A. Sillanpaa, Raphael Khan, Tero T. Heikkila +1
The experimental observation of quantum phenomena in mechanical degrees of freedom is difficult, as the systems become linear towards low energies and the quantum limit, and thus r…
