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 with current-carrying wires, a trapping potential can be formed when applying a homogeneous magnetic bias field perpendicular to the fiber axis. We discuss this scheme in detail for laser-cooled cesium atoms and find trap depths and trap frequencies comparable to the two-color nanofiber-based trapping scheme but with…

Microwave coherent manipulation of cold atoms in optically induced fictitious magnetic traps on an atom chip
We propose a novel on-chip platform for controlling and manipulating cold atoms precisely and coherently. The scheme is achieved by producing optically induced fictitious magnetic traps (OFMTs) with
Interaction of laser-cooled 87 Rb atoms with higher order modes of an optical nanofibre
Optical nanofibres are used to confine light to sub-wavelength regions and are very promising tools for the development of optical fibre-based quantum networks using cold, neutral atoms. To date,

Optical nanofibres are increasingly being used in cold atom experiments due to their versatility and the clear advantages they have when developing all-fibred systems for quantum technologies. They
Achievement and steering of light-induced sub-wavelength longitudinal magnetization chain.
The light-induced magnetization distributions for a high numerical aperture focusing configuration with an azimuthally polarized Bessel-Gaussian beam modulated by optimized vortex binary filters are investigated based on the inverse Faraday effect and it is found that the displacement distance of the longitudinal magnetization chain is proportional to the phase difference between the inner circle and outer ring of the vortexbinary filters, thus giving rise to the steerable magnetized chain.

E engineered directional photonic reservoirs could lead to the development of complex quantum networks that, for example, could simulate novel classes of quantum many-body systems.
Self-Calibrating Vector Atomic Magnetometry through Microwave Polarization Reconstruction.
This work presents a method for converting a naturally scalar atomic magnetometer into a vector magnetometer by exploiting the polarization dependence of hyperfine transitions in rubidium atoms, and fully determines the polarization ellipse of an applied microwave field.

Three-dimensional super-resolution longitudinal magnetization spot arrays
An all-optical control of all the properties of light-induced magnetization spot arrays has been demonstrated for the first time and opens up broad applications in magnetic-opticals devices such as confocal and multifocal magnetic resonance microscopy, 3D ultrahigh-density magneto-optic memory, and light- induced magneti-lithography.


Optical interface created by laser-cooled atoms trapped in the evanescent field surrounding an optical nanofiber.
This technique opens the route towards the direct integration of laser-cooled atomic ensembles within fiber networks, an important prerequisite for large scale quantum communication schemes, and is ideally suited to the realization of hybrid quantum systems that combine atoms with, e.g., solid state quantum devices.

Coupling a Single Trapped Atom to a Nanoscale Optical Cavity
A deterministic interface between a single trapped rubidium atom and a nanoscale photonic crystal cavity is demonstrated and Precise control over the atom's position allows us to probe the cavity near-field with a resolution below the diffraction limit and to observe large atom-photon coupling.
Demonstration of a state-insensitive, compensated nanofiber trap.
An optical trap is reported that localizes single Cs atoms ≃215  nm from the surface of a dielectric nanofiber by operating at magic wavelengths for pairs of counterpropagating red- and blue-detuned trapping beams, and differential scalar light shifts are eliminated and vector shifts are suppressed.
