Interaction of atomic systems with quantum vacuum beyond electric dipole approximation
Miriam Kosik, Oleksandr Burlayenko, Ivan Fernandez-Corbaton +2
The photonic environment can significantly influence emission properties and interactions among atomic systems. In such scenarios, frequently the electric dipole approximation is a…
Directional coupling of emitters into waveguides: A symmetry perspective
Aristeidis G. Lamprianidis, Xavier Zambrana-Puyalto, Carsten Rockstuhl +1
Recent experiments demonstrated strongly directional coupling of light into waveguide modes. We identify here the mechanisms behind this effect. We consider emitters near a wavegui…
Superconducting nanowire single-photon spectrometer exploiting cascaded photonic crystal cavities
Youngsun Yun, Andreas Vetter, Robin Stegmueller +4
Superconducting nanowire single-photon detectors promise efficient (~100%) and fast (~Gcps) detection of light at the single-photon level. They constitute one of the building block…
Using states with a large photon number variance to increase quantum Fisher information in single-mode phase estimation
Changhyoup Lee, Changhun Oh, Hyunseok Jeong +2
When estimating the phase of a single mode, the quantum Fisher information for a pure probe state is proportional to the photon number variance of the probe state. In this work, we…
Helicity-preserving optical cavity modes for enhanced sensing of chiral molecules
Joshua Feis, Dominik Beutel, Julian Köpfler +4
Researchers routinely sense molecules by their infrared vibrational "fingerprint" absorption resonances. In addition, the dominant handedness of chiral molecules can be detected by…
Enhancement of and interference among higher order multipole transitions in molecules near a plasmonic nanoantenna
Evgenia Rusak, Jakob Straubel, Piotr Gładysz +6
Spontaneous emission of quantum emitters can be modified by engineering their optical environment. This allows a resonant nanoantenna to significantly modify the radiative properti…
