Two-photon edge states in photonic topological insulators: topological protection versus degree of entanglement
Konrad Tschernig, Alvaro Jimenez-Galan, Demetrios N. Christodoulides +4
Topological insulators combine insulating properties in the bulk with scattering-free transport along edges, supporting dissipationless unidirectional energy and information flow e…
Direct observation of the particle exchange phase of photons
Konrad Tschernig, Chris Müller, Malte Smoor +5
Quantum theory stipulates that if two particles are identical in all physical aspects, the allowed states of the system are either symmetric or antisymmetric with respect to permut…
Topological Protection in non-Hermitian Haldane Honeycomb Lattices
Pablo Reséndiz-Vázquez, Konrad Tschernig, Armando Perez-Leija +2
Topological phenomena in non-Hermitian systems have recently become a subject of great interest in the photonics and condensed-matter communities. In particular, the possibility of…
Exceptional points of any order in a single, lossy, waveguide beamsplitter by photon-number-resolved detection
Mario A. Quiroz-Juárez, Armando Perez-Leija, Konrad Tschernig +5
Exceptional points (EPs) are degeneracies of non-Hermitian operators where, in addition to the eigenvalues, corresponding eigenmodes become degenerate. Classical and quantum photon…
Multiphoton Discrete Fractional Fourier Dynamics in Waveguide Beam Splitters
Konrad Tschernig, Roberto de J. Leon-Montiel, Omar S. Magana-Loaiza +3
We demonstrate that when a waveguide beam splitter (BS) is excited by N indistinguishable photons, the arising multiphoton states evolve in a way as if they were coupled to each ot…
