- Authors: Micha{\l} Lipka, Micha{\l} Parniak
- Abstract summary: We experimentally demonstrate how the Hong-Ou-Mandel effect can be spectrally-resolved and harnessed to characterize a complex temporal mode of a single-photon.
The combination of bosonic quantum behavior with bandwidth-mismatched light-atom interaction is of fundamental importance for a deeper understanding of both phenomena, as well as their engineering offering applications in the characterization of ultra-fast transient processes.

- Abstract: Single photons exhibit inherently quantum and unintuitive properties such as
the Hong-ou-Mandel effect, demonstrating their bosonic and quantized nature,
yet at the same time may correspond to single excitations of spatial or
temporal modes with a very complex structure. Those two features are rarely
seen together. Here we experimentally demonstrate how the Hong-Ou-Mandel effect
can be spectrally-resolved and harnessed to characterize a complex temporal
mode of a single-photon \textendash{} a zero-area pulse \textendash{} obtained
via a resonant interaction of a terahertz-bandwidth photon with a narrow
gigahertz-wide atomic transition of atomic vapor. The combination of bosonic
quantum behavior with bandwidth-mismatched light-atom interaction is of
fundamental importance for a deeper understanding of both phenomena, as well as
their engineering offering applications in the characterization of ultra-fast
transient processes.

We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide.
When the frequency of this motion approaches twice the qubit resonance frequency, it induces parametric generation of photons and excitation of the qubits.
We develop a comprehensive general theoretical framework that incorporates both perturbative diagrammatic techniques and a rigorous master-equation approach.

Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations.
One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them.
Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.
