Strong Dipole-Dipole Interactions via Enhanced Light-Matter Coupling in Composite Nanofiber Waveguides
Kritika Jain, Lewis Ruks, Fam le Kien +1
We study the interaction of emitters with a composite waveguide formed from two parallel optical nanofibers in currently unexplored regimes of experimental importance for atomic ga…
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…
Propagation of nanofiber-guided light through an array of atoms
Fam Le Kien, Arno Rauschenbeutel
We study the propagation of nanofiber-guided light through an array of atomic cesium, taking into account the transitions between the hyperfine levels and $6P_{3/2}F'…
Anisotropy in scattering of light from an atom into the guided modes of a nanofiber
Fam Le Kien, A. Rauschenbeutel
We study the scattering of guided light from a multilevel cesium atom with the transitions between the hyperfine levels and of the line into the…
Negative azimuthal force of a nanofiber-guided light on a particle
Fam Le Kien, Arno Rauschenbeutel
We calculate the force of a quasicircularly polarized guided light field of a nanofiber on a dielectric spherical particle. We show that the orbital parts of the axial and azimutha…
Optical wire trap for cold neutral atoms
Philipp Schneeweiss, Fam Le Kien, Arno Rauschenbeutel
We propose a trap for cold neutral atoms using a fictitious magnetic field induced by a nanofiber-guided light field. In close analogy to magnetic side-guide wire traps realized wi…
State-dependent potentials in a nanofiber-based two-color trap for cold atoms
Fam Le Kien, Philipp Schneeweiss, Arno Rauschenbeutel
We analyze the ac Stark shift of a cesium atom interacting with far-off-resonance guided light fields in the nanofiber-based two-color optical dipole trap realized by Vetsch \texti…
Quantum dynamics of an atom orbiting around an optical nanofiber
Fam Le Kien, Kohzo Hakuta, Philipp Schneeweiss +1
We propose a novel platform for the investigation of quantum wave packet dynamics, offering a complementary approach to existing theoretical models and experimental systems. It rel…
Efficient channeling of fluorescence photons from single quantum dots into guided modes of optical nanofiber
Ramachandrarao Yalla, Fam Le Kien, M. Morinaga +1
We experimentally demonstrate the efficient channeling of fluorescence photons from single q-dots on optical nanofiber into the guided modes, by measuring the photon-count rates th…
Effect of an atom on a quantum guided field in a weakly driven fiber-Bragg-grating cavity
Fam Le Kien, K. Hakuta
We study the interaction of an atom with a quantum guided field in a weakly driven fiber-Bragg-grating (FBG) cavity. We present an effective Hamiltonian and derive the density-matr…
Cavity-enhanced channeling of emission from an atom into a nanofiber
Fam Le Kien, K. Hakuta
We study spontaneous emission of an atom near a nanofiber with two fiber-Bragg-grating (FBG) mirrors. We show that the coupling between the atom and the guided modes of the nanofib…
