Long-lifetime coherence in a quantum emitter induced by a metasurface
Emmanuel Lassalle, Philippe Lalanne, Syed Aljunid +4
An anisotropic quantum vacuum (AQV) has been predicted to induce quantum interferences during the spontaneous emission process in an atomic -transition [G. S. Agarwal, Phys. Rev…
Excitation of a single atom with exponentially rising light pulses
Syed Abdullah Aljunid, Gleb Maslennikov, Yimin Wang +3
We investigate the interaction between a single atom and optical pulses in a coherent state with a controlled temporal envelope. In a comparison between a rising exponential and a…
Preparation of an Exponentially Rising Optical Pulse for Efficient Excitation of Single Atoms in Free Space
Hoang Lan Dao, Syed Abdullah Aljunid, Gleb Maslennikov +1
We report on a simple method to prepare optical pulses with exponentially rising envelope on the time scale of a few ns. The scheme is based on the exponential transfer function of…
Interaction of light with a single atom in the strong focusing regime
Syed Abdullah Aljunid, Brenda Chng, Martin Paesold +2
We consider the near-resonant interaction between a single atom and a focused light mode, where a single atom localized at the focus of a lens can scatter a significant fraction of…
Phase shift of a weak coherent beam induced by a single atom
Syed Abdullah Aljunid, Meng Khoon Tey, Brenda Chng +4
We report on a direct measurement of a phase shift on a weak coherent beam by a single Rb-87 atom in a Mach-Zehnder interferometer. A maximum phase shift of about 1 degree is obser…
Interfacing light and single atoms with a lens
Meng Khoon Tey, Gleb Maslennikov, Timothy C. H. Liew +6
We characterize the interaction between a single atom or similar microscopic system and a light field via the scattering ratio. For that, we first derive the electrical field in a…
