Doppler-free selective reflection spectroscopy of electric-quadrupole transitions
Eng Aik Chan, Syed Abdullah Aljunid, Athanasios Laliotis +2
Electric-dipole-forbidden transitions play an important role as in quantum sensing, quantum information, and fundamental test in physics. As such, the development of novel and sens…
Single atom in a superoscillatory optical trap
Hamim Mahmud Rivy, Syed A. Aljunid, Emmanuel Lassalle +2
Optical tweezers have become essential tools to manipulate atoms or molecules at a single particle level. However, using standard diffracted-limited optical systems, the transverse…
Plasmono-Atomic Interactions on a Fiber Tip
Eng Aik Chan, Giorgio Adamo, Syed Abdullah Aljunid +3
Light-atom interaction can be engineered by interfacing atoms with various specially designed media and optical fibers are convenient platforms for realization of compact interface…
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…
Large optical depth frequency modulation spectroscopy
Chang Chi Kwong, Eng Aik Chan, Syed Abdullah Aljunid +2
Band-resolved frequency modulation spectroscopy is a common method to measure weak signals of radiative ensembles. When the optical depth of the medium is large, the signal drops e…
Coupling of atomic quadrupole transitions with resonant surface plasmons
Eng Aik Chan, Syed Abdullah Aljunid, Giorgio Adamo +3
We report on the coupling of an electric quadrupole transition in atom with plasmonic excitation in a nanostructured metallic metamaterial. The quadrupole transition at 685 nm in t…
