Coherent nonlinear optics of quantum emitters in nanophotonic waveguides
Pierre Türschmann, Hanna Le Jeannic, Signe F. Simonsen +5
Coherent quantum optics, where the interaction of a photon with an emitter does not scramble phase coherence, lies at the heart of many quantum optical effects and emerging technol…
Chiral emission into nanophotonic resonators
Diego Martín-Cano, Harald R. Haakh, Nir Rotenberg
Chiral emission, where the handedness of a transition dipole determines the direction in which a photon is emitted, has recently been observed from atoms and quantum dots coupled t…
Small slot waveguide rings for on-chip quantum optical circuits
Nir Rotenberg, Pierre Tuerschmann, Harald Haakh +3
Nanophotonic interfaces between single emitters and light promise to enable new quantum optical technologies. Here, we use a combination of finite element simulations and analytic…
Polaritonic states in a dielectric nanoguide: localization and strong coupling
Harald R. Haakh, Sanli Faez, Vahid Sandoghdar
Propagation of light through dielectrics lies at the heart of optics. However, this ubiquitous process is commonly described using phenomenological dielectric function $\varepsilon…
Reduction of nonclassical fluctuations by entangled nonidentical emitters in nanophotonic environments
Harald R. Haakh, Diego Martín-Cano
We propose a scheme in which broadband nanostructures allow to generate squeezed light and entanglement of quantum emitters that are extremely far detuned. It is shown that the red…
Modified and controllable dispersion interaction in a 1D waveguide geometry
Harald R. Haakh, Stefan Scheel
Dispersion interactions such as the van der Waals interaction between atoms or molecules derive from quantum fluctuations of the electromagnetic field and can be understood as the…
Coherent Interaction of Light and Single Molecules in a Dielectric Nanoguide
Sanli Faez, Pierre Türschmann, Harald R. Haakh +2
We present a new scheme for performing optical spectroscopy on single molecules. A glass capillary with a diameter of 600 nm filled with an organic crystal tightly guides the excit…
Large suppression of quantum fluctuations of light from a single emitter by an optical nanostructure
Diego Martín Cano, Harald R. Haakh, Karim Murr +1
We investigate the reduction of the electromagnetic field fluctuations in resonance fluorescence from a single emitter coupled to an optical nanostructure. We find that such hybrid…
Dynamical Casimir-Polder interaction between an atom and surface plasmons
Harald R. Haakh, Carsten Henkel, Salvatore Spagnolo +2
We investigate the time-dependent Casimir-Polder potential of a polarizable two-level atom placed near a surface of arbitrary material, after a sudden change in the parameters of t…
Mode structure and polaritonic contributions to the Casimir effect in a magneto-dielectric cavity
Harald R. Haakh, Francesco Intravaia
We present a full analysis of the mode spectrum in a cavity formed by two parallel plates, one of which is a magneto-dielectric, e.g. a metamaterial, while the other one is metalli…
Feynman Diagrams for Dispersion Interactions Out of Equilibrium -- Two-Body Potentials for Atoms with Initial Excitation
Harald R. Haakh, Jürgen Schiefele, Carsten Henkel
Diagrammatic techniques are well-known in the calculation of dispersion interactions between atoms or molecules. The multipolar coupling scheme combined with Feynman ordered diagra…
Magnetic near fields as a probe of charge transport in spatially dispersive conductors
Harald R. Haakh, Carsten Henkel
We calculate magnetic field fluctuations above a conductor with a nonlocal response (spatial dispersion) and consider a large range of distances. The cross-over from ballistic to d…
Prospects for fast Rydberg gates on an atom chip
Matthias M. Müller, Harald R. Haakh, Tommaso Calarco +2
Atom chips are a promising candidate for a scalable architecture for quantum information processing provided a universal set of gates can be implemented with high fidelity. The dif…
Temperature dependence of the magnetic Casimir-Polder interaction
H. Haakh, F. Intravaia, C. Henkel +4
We analyze the magnetic dipole contribution to atom-surface dispersion forces. Unlike its electrical counterpart, it involves small transition frequencies that are comparable to th…
