Water as a Free Electric Dipole Laser

Phys. Rev. Lett. 61, 1085 – Published 29 August 1988
Emilio Del Giudice, Giuliano Preparata, and Giuseppe Vitiello


We show that the usually neglected interaction between the electric dipole of the water molecule and the quantized electromagnetic radiation field can be treated in the context of a recent quantum field theoretical formulation of collective dynamics. We find the emergence of collective modes and the appearance of permanent electric polarization around any electrically polarized impurity.
