Photon-bunching measurement after 2x25km of standard optical fibers
M. Halder, S. Tanzilli, H. de Riedmatten +3
To show the feasibility of a long distance partial Bell-State measurement, a Hong-Ou-Mandel experiment with coherent photons is reported. Pairs of degenerate photons at telecom wav…
Reciprocal space mapping of magnetic order in thick epitaxial MnSi films
B. Wiedemann, A. Chacon, S. L. Zhang +9
We report grazing incidence small angle neutron scattering (GISANS) and complementary off-specular neutron reflectometry (OSR) of the magnetic order in a single-crystalline epitaxi…
Entropy-limited topological protection of skyrmions
J. Wild, T. N. G. Meier, S. Pöllath +11
Magnetic skyrmions are topologically protected whirls that decay through singular magnetic configurations known as Bloch points. We have used Lorentz transmission electron microsco…
Formation of a topological non-Fermi liquid in MnSi
R. Ritz, M. Halder, M. Wagner +3
Fermi liquid theory provides a remarkably powerful framework for the description of the conduction electrons in metals and their ordering phenomena, such as superconductivity, ferr…
Amplitude and phase modulation of time-energy entangled two-photon states
F. Zäh, M. Halder, T. Feurer
We experimentally demonstrate amplitude and phase modulation of a time-energy entangled two-photon wave function. The entangled photons are produced by spontaneous parametric down-…
Giant generic topological Hall resistivity of MnSi under pressure
R. Ritz, M. Halder, C. Franz +5
We report detailed low temperature magnetotransport and magnetization measurements in MnSi under pressures up to . Tracking the role of sample quality, pressure…
