Rydberg electromagnetically induced transparency based laser lock to Zeeman sublevels with 0.6 GHz scanning range
Alexey Vylegzhanin, Sile Nic Chormaic, Dylan J. Brown
We propose a technique for frequency locking a laser to the Zeeman sublevel transitions between the 5P intermediate and 32D Rydberg states in Rb. This method…
Enabling self-induced back-action trapping of gold nanoparticles in metamaterial plasmonic tweezers
Theodoros D. Bouloumis, Domna G. Kotsifaki, Sile Nic Chormaic
The pursuit for efficient nanoparticle trapping with low powers has led to optical tweezers technology moving from the conventional free-space configuration to advanced plasmonic t…
Asymmetric split-ring plasmonic nanostructures for optical sensing of Escherichia coli
Domna G. Kotsifaki, Rajiv Ranjan Singh, Sile Nic Chormaic +1
Strategies for in-liquid micro-organism detection are crucial for the clinical and pharmaceutical industries. While Raman spectroscopy is a promising label-free technique for micro…
Transfer of angular momentum of guided light to an atom with an electric quadrupole transition near an optical nanofiber
Fam Le Kien, Sile Nic Chormaic, Thomas Busch
We study the transfer of angular momentum of guided photons to a two-level atom with an electric quadrupole transition near an optical nanofiber. We show that the generation of the…
Optical force between two coupled identical parallel optical nanofibers
Fam Le Kien, Sile Nic Chormaic, Thomas Busch
We study the optical force between two coupled parallel identical nanofibers using the rigorous array mode theory. We show that the forces of the even array modes are attractive, w…
Repulsive Casimir-Polder potentials of low-lying excited states of a multilevel alkali-metal atom near an optical nanofiber
Fam Le Kien, D. F. Kornovan, Sile Nic Chormaic +1
We study the Casimir-Polder potential of a multilevel alkali-metal atom near an optical nanofiber. We calculate the mean potential of the atom in a fine-structure level. We perform…
