One-photon wavepacket interacting with two separated atoms in a one-dimensional waveguide: Influence of virtual photons

Understand

We present a theoretical study of one photon wave-packet scattered by two atoms in one dimensional waveguide.

• We investigate the role of non rotating wave approximation terms to take into account correctly for the effects of the virtual photons that are exchanged between the atoms.
• These terms are shown to influence drastically the reflected and the transmitted fields, imposing strict constraints on their temporal envelopes.
