High-purity single photons obtained with moderate-NA optics from SiV center in nanodiamonds on a bullseye antenna

open access: yesNew Journal of Physics, 2021
Coherent exchange of single photons is at the heart of applied quantum optics. The negatively-charged silicon vacancy center in diamond is among most promising sources for coherent single photons.

General theory of Bose-Einstein condensation applied to an ideal quantum gas of photons in an optical microcavity [PDF]

open access: yesPhysical Review A, 2019
This paper provides, first, a succinct theoretical derivation of Bose-Einstein condensation in a grand-canonical ideal photon gas elaborating on previous results [M\"uller, Ann. Phys. 184, 219 (1988); Physica A (Amsterdam, Neth.) 139, 165 (1986)] additionally including new results on the condensate function and, second, applies this framework to ...

Wannier functions of defective photonic crystals with broken translational symmetry

open access: yesScientific Reports
Wannier functions offer a complete and well-suited real-space description for perfect crystals, based on localized states. With broken crystalline translational symmetry, however, direct unitary transformation from Bloch functions is not straightforward.
