Experimental observation of an anomalous weak value without post-selection

Experimental observation of weak non-Markovianity

Non-Markovianity has recently attracted large interest due to significant advances in its characterization and its exploitation for quantum information processing. However, up to now, only non-Markovian regimes featuring environment to system backflow of information (strong non-Markovianity) have been experimentally simulated. In this work, using an all-optical setup we simulate and observe the...

Control of optical spin Hall shift in phase-discontinuity metasurface by weak value measurement post-selection

Spin Hall effect of light is a spin-dependent transverse shift of optical beam propagating along a curved trajectory, where the refractive index gradient plays a role of the electric field in spin Hall effect of solid-state systems. In order to observe optical spin Hall shift in a refraction taking place at air-glass interface, an amplification technique was necessary such as quantum weak measu...

Observation of an anomalous adsorption in a critical binary mixture

2014 We have experimentally demonstrated the existence of a new critical anomaly in a binary mixture, due to the preferential adsorption of one of the components onto a solid wall. J.

Observation of an anomalous positron abundance in the cosmic radiation

Positrons are known to be produced in interactions between cosmic-ray nuclei and interstellar matter (“secondary production”). Positrons may, however, also be created by dark matter particle annihilations in the galactic halo or in the magnetospheres of near-by pulsars. The nature of dark matter is one of the most prominent open questions in science today. An observation of positrons from pulsa...
