Chiral excitation of a single atom by a single photon in a guided mode of a nanofiber
Fam Le Kien, Sile Nic Chormaic, Thomas Busch
We study the interaction between a single two-level atom and a single-photon probe pulse in a guided mode of a nanofiber. We examine the situation of chiral interaction, where the…

Torque of guided light on an atom near an optical nanofiber
Fam Le Kien, Thomas Busch
We calculate analytically and numerically the axial orbital and spin torques of guided light on a two-level atom near an optical nanofiber. We show that the generation of these tor…

Channeling of spontaneous emission from an atom into the fundamental and higher-order modes of a vacuum-clad ultrathin optical fiber
Fam Le Kien, S. Sahar S. Hejazi, Thomas Busch +2
We study spontaneous emission from a rubidium atom into the fundamental and higher-order modes of a vacuum-clad ultrathin optical fiber. We show that the spontaneous emission rate…
