Strong Photon-Photon Interactions at the Single-Photon Level
Engineering light at the single photon level is a long-standing goal in physics. In this thesis, we investigate optical nonlinearities at the single photon level orchestrated by an optical cavity. We demonstrate an all-optical transistor where one stored ‘gate’ photon controls the propagation of a ’source’ light beam. The system is based on EIT and a highcooperativity cavity. Each ’gate’ photon...
متن کاملNonlinear collective effects in photon–photon and photon–plasma interactions
We consider strong-field effects in laboratory and astrophysical plasmas and high intensity laser and cavity systems, related to quantum electrodynamical (QED) photon–photon scattering. Current state-of-the-art laser facilities are close to reaching energy scales at which laboratory astrophysics will become possible. In such high energy density laboratory astrophysical systems, quantum electrod...
متن کاملHadronic photon-photon interactions at high energies.
Photon-photon collisions are investigated in the framework of the two-component Dual Parton Model. The model contains contributions from direct, resolved soft and resolved hard interactions. All free parameters of the model are determined in fits to hadronhadron and photon-hadron cross section data. The model is shown to agree well to hadron production data from hadron-hadron and photon-hadron ...
متن کاملTesting Qcd in Photon-photon Interactions
x = Q 2p · q = Q Q2 +W 2 + P 2 ; y = p · q p · k are the usual dimensionless variables of deep-inelastic scattering. W 2 = (q+p) is the squared invariant mass of the hadronic final state. The negative fourmomentum squared, P 2 = −p2, of the quasi-real target photon is approximately zero. In leading order (LO) the photon structure function F γ 2 (x,Q ) is related to the sum over the quark densit...
متن کاملPhoton-photon interactions via Rydberg blockade.
We develop the theory of light propagation under the conditions of electromagnetically induced transparency in systems involving strongly interacting Rydberg states. Taking into account the quantum nature and the spatial propagation of light, we analyze interactions involving few-photon pulses. We show that this system can be used for the generation of nonclassical states of light including tra...
