    Invited Talk: Neutron interferometry for studies of experimental quantum mechanics

    Yuji Hasegawa1,21Atominstitut, TU-Wien, Stadionallee 2, A-1020 Vienna, AUSTRIA2Division of Applied Physics, Hokkaido University, Sapporo, Hokkaido, 060-0808, JAPAN Neutron interferometers provide ideal situations of experimental observations of interference between coherently split, well-separated beams of matter waves, in this case neutron de Broglie waves. Interferometers made of perfect silicon crystal was invented for x-rays in 1964 and first performance with neutrons was confirmed by Rauch, Treimer and Bonse at the Atominstitut, Vienna in 1974. The Atominstitut was distinguished as an European-Physical-Society (EPS) Historic Site on 22 May 2019. Over the past almost half century, neutron interferometer experiments are bringing impact on fundamental quantum and neutron physics [1-3].Since the time-independent Schrödinger equation, i.e.,…
