Abstract:
We investigate the scattered field from N identical two-level atoms resonantly driven by a weak coherent field in a one-dimensional waveguide. For atoms separated by the drive wavelength, increasing the number of atoms suppresses transmission while enhancing photon bunching. Transmission becomes a superbunched (N+1)-photon scattering process that is predominantly incoherent. Remarkably, we find that transmission occurs through a process where all N atoms are excited, enabling novel heralded multiphoton state generation with applications in long-distance entanglement and quantum metrology.

Propagation of Waves
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...
Electromagnetic Waves in Matter
Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the medium, μ.
Furthermore, the...
