Order-invariant two-photon quantum correlations in PT-symmetric interferometers
Tom A. W. Wolterink, Matthias Heinrich, Stefan Scheel +1
Multiphoton correlations in linear photonic quantum networks are governed by matrix permanents. Yet, surprisingly few systematic properties of these crucial algebraic objects are k…
Particle-Number Threshold for Non-Abelian Geometric Phases
Julien Pinske, Vincent Burgtorf, Stefan Scheel
When a quantum state traverses a path, while being under the influence of a gauge potential, it acquires a geometric phase that is often more than just a scalar quantity. The varie…
Geometrically robust linear optics from non-Abelian geometric phases
Julien Pinske, Stefan Scheel
We construct a unified operator framework for quantum holonomies generated from bosonic systems. For a system whose Hamiltonian is bilinear in the creation and annihilation operato…
Intermediate-range Casimir-Polder interaction probed by high-order slow atom diffraction
C Garcion, N Fabre, H Bricha +4
At nanometer separation, the dominant interaction between an atom and a material surface is the fluctuation-induced Casimir-Polder potential. We demonstrate that slow atoms crossin…
Interseries dipole transitions from yellow to green excitons in cuprous oxide
Patric Rommel, Jörg Main, Sjard Ole Krüger +1
We study dipole interseries transitions between the yellow and green exciton series in cuprous oxide including the complex valence band structure. To this end, we extend previous s…
Symmetry-protected non-Abelian geometric phases in optical waveguides with nonorthogonal modes
Julien Pinske, Stefan Scheel
The generation of non-Abelian geometric phases from a system of evanescently coupled waveguides is extended towards the framework of nonorthogonal coupled-mode theory. Here, we stu…
