Electric-field-induced two-photon processes

Two-Photon Voltmeter for Measuring a Molecular Electric Field**

We present a new approach for determining the strength of the dipolar solute-induced reaction field, along with the ground- and excited-state electrostatic dipole moments and polarizability of a solvated chromophore, using exclusively one-photon and two-photon absorption measurements. We verify the approach on two benchmark chromophores N,N-dimethyl-6-propionyl-2-naphthylamine (prodan) and coum...

Laser-induced detachment processes in an electric field.

Electric field-induced reorganization of two-component supported bilayer membranes.

Application of electric fields tangent to the plane of a confined patch of fluid bilayer membrane can create lateral concentration gradients of the lipids. A thermodynamic model of this steady-state behavior is developed for binary systems and tested with experiments in supported lipid bilayers. The model uses Flory's approximation for the entropy of mixing and allows for effects arising when t...

Photon Structure Functions and Azimuthal * Asymmetries in Two-photon Processes

ABSTRACT Based on the recently developed framework of Curci, Furmanski and Petronzio, we derive the photon structure functions in quantum chromodynamics (QCD). Then we perform QCD calculations for the azimuthal asyrmnetries of jets in two-photon processes. We find that in contrast to the case of lepton-hadron scatterings the deep inelastic e+ereaction via two-photon exchange is expected to show...

Two-photon processes in faint biphoton fields

The goal of this research is to determine and study a physical system that will enable a fast and intrinsically two-photon detector, which would be of interest for quantum information and metrology applications. We consider two types of twophoton processes that can be observed using a very faint, but quantum-correlated biphoton field. These are optical up-conversion and an external photoelectri...
