A Sum Rule for Nonlinear Optical Susceptibilities
Luciana C. Davila Romero, David L. Andrews
It is explicitly shown, for optical processes arbitrarily comprising two-, three- or four-photon interactions, that the sum over all matter states of any optical susceptibility is…
Eliminating ground-state dipole moments in quantum optics via canonical transformation
Gediminas Juzeliunas, Luciana Davila Romero, David L. Andrews
By means of a canonical transformation it is shown how it is possible to recast the equations for molecular nonlinear optics to completely eliminate ground-state static dipole coup…
Molecular chirality and the orbital angular momentum of light
David L. Andrews, Luciana C. Davila Romero, Mohamed Babiker
Optical beams with a new and distinctive type of helicity have become the subject of much recent interest. While circularly polarised light comprises photons with spin angular mome…
