Quantum entanglement and statistics of photons on a beam splitter in the form of coupled waveguides
It is well known that a beam splitter (BS) can be used as a source of photon quantum entanglement. This is due to the fact that the statistics of photons changes at the output ports of the BS. Usually, quantum entanglement and photon statistics take into

An inter-comparison of Arctic synoptic scale storms between four global reanalysis datasets [PDF]
The Arctic is becoming more accessible as sea ice extent continues to decline, resulting in higher human exposure to Arctic storms. This study compares Arctic storm characteristics between the ECMWF-Interim Reanalysis, 55-year Japanese Reanalysis, NASA ...
