Coupling of Light and Mechanics in a Photonic Crystal Waveguide
J. -B. Béguin, Z. Qin, X. Luan +1
Observations of thermally driven transverse vibration of a photonic crystal waveguide (PCW) are reported. The PCW consists of two parallel nanobeams with a 240 nm vacuum gap betwee…
Measurement and simulation of atomic motion in nanoscale optical trapping potentials
Signe B. Markussen, Jürgen Appel, Christoffer Østfeldt +3
Atoms trapped in the evanescent field around a nanofiber experience strong coupling to the light guided in the fiber mode. However, due to the intrinsically strong positional depen…
The integration of photonic crystal waveguides with atom arrays in optical tweezers
X. Luan, J. -B. Béguin, A. P. Burgers +3
Integrating nanophotonics and cold atoms has drawn increasing interest in recent years due to diverse applications in quantum information science and the exploration of quantum man…
Dipole force free optical control and cooling of nanofiber trapped atoms
Christoffer Østfeldt, Jean-Baptiste Béguin, Freja T. Pedersen +3
The evanescent field surrounding nano-scale optical waveguides offers an efficient interface between light and mesoscopic ensembles of neutral atoms. However, the thermal motion of…
Coherent backscattering of light off one-dimensional atomic strings
H. L. Sørensen, J. -B. Béguin, K. W. Kluge +5
We present the first experimental realization of coherent Bragg scattering off a one-dimensional (1D) system -- two strings of atoms strongly coupled to a single photonic mode -- r…
Generation and detection of a sub-Poissonian atom number distribution in a one-dimensional optical lattice
J. -B. Béguin, E. Bookjans, S. L. Christensen +4
We demonstrate preparation and detection of an atom number distribution in a one-dimensional atomic lattice with the variance dB below the Poissonian noise level. A mesoscopi…
Towards quantum state tomography of a single polariton state of an atomic ensemble
S. L. Christensen, J. B. Béguin, H. L. Sørensen +5
We present a proposal and a feasibility study for the creation and quantum state tomography of a single polariton state of an atomic ensemble. The collective non-classical and non-…
