Simulating Dicke like superradiance with classical light sources
D. Bhatti, S. Oppel, R. Wiegner +2
In this paper we investigate the close relationship between Dicke superradiance, originally predicted for an ensemble of two-level atoms in entangled states, and the Hanbury Brown…
Simulating superradiance from higher-order-intensity-correlation measurements: Single atoms
R. Wiegner, S. Oppel, D. Bhatti +2
Superradiance typically requires preparation of atoms in highly entangled multi-particle states, the so-called Dicke states. In this paper we discuss an alternative route where we…
Hong-Ou-Mandel interference without beam splitters
S. Mährlein, S. Oppel, R. Wiegner +1
We propose a new interferometric setup which displays a completely destructive generalized N-photon Hong-Ou-Mandel interference. The key property of this scheme is that is does not…
Directional superradiant emission from statistically independent incoherent non-classical and classical sources
S. Oppel, R. Wiegner, G. S. Agarwal +1
Superradiance is one of the outstanding problems in quantum optics since Dicke introduced the concept of enhanced directional spontaneous emission by an ensemble of identical two-l…
Measurement induced focussing of radiation from independent single photon sources
R. Wiegner, S. Oppel, J. von Zanthier +1
We present a technique based on multi-photon detection which leads to a strong focussing of photons scattered by independent single photon emitters. For N single photon sources it…
Quantum interference initiated super- and subradiant emission from entangled atoms
R. Wiegner, J. von Zanthier, G. S. Agarwal
We calculate the radiative characteristics of emission from a system of entangled atoms which can have a relative distance larger than the emission wavelength. We develop a quantum…
Non-locality from N > 2 Independent Single Photon Emitters
C. Thiel, R. Wiegner, J. von Zanthier +1
We demonstrate that intensity correlations of second order in the fluorescence light of N > 2 single- photon emitters may violate locality while the visibility of the signal remain…
Quantum interference and non-locality of independent photons from disparate sources
R. Wiegner, J. von Zanthier, G. S. Agarwal
We quantitatively investigate the non-classicality and non-locality of a whole new class of mixed disparate quantum and semiquantum photon sources at the quantum-classical boundary…
Creating path entanglement and violating Bell inequalities by independent photon sources
R. Wiegner, C. Thiel, J. von Zanthier +1
We demonstrate a novel approach of violating position dependent Bell inequalities by photons emitted via independent photon sources in free space. We trace this violation back to p…
