Despite the proven power of neutrons for material characterization and studies of fundamental physics, neutron science has not been able to fully integrate these techniques because of small transverse coherence lengths, the relatively poor resolution of spatial detectors, and low fluence rates. Here, we demonstrate methods that are practical with the existing technologies and show the experimental achievement of neutron helical wavefronts that carry well-defined orbital angular momentum values. We discuss possible applications and extensions to spin-orbit correlations and material characterization techniques.<\/jats:p>","DOI":"10.1126\/sciadv.add2002","type":"journal-article","created":{"date-parts":[[2022,11,18]],"date-time":"2022-11-18T13:58:38Z","timestamp":1668779918000},"source":"Crossref","is-referenced-by-count":39,"title":["Experimental realization of neutron helical waves"],"prefix":"10.1126","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8575-3367","authenticated-orcid":true,"given":"Dusan","family":"Sarenac","sequence":"first","affiliation":[{"name":"Institute for Quantum Computing, University of Waterloo, Waterloo, ON N2L3G1, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9122-0348","authenticated-orcid":true,"given":"Melissa E.","family":"Henderson","sequence":"additional","affiliation":[{"name":"Institute for Quantum Computing, University of Waterloo, Waterloo, ON N2L3G1, Canada."},{"name":"Department of Physics and Astronomy, University of Waterloo, Waterloo, ON N2L3G1, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3774-599X","authenticated-orcid":true,"given":"Huseyin","family":"Ekinci","sequence":"additional","affiliation":[{"name":"Institute for Quantum Computing, University of Waterloo, Waterloo, ON N2L3G1, Canada."},{"name":"Department of Physics and Astronomy, University of Waterloo, Waterloo, ON N2L3G1, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8724-9885","authenticated-orcid":true,"given":"Charles W.","family":"Clark","sequence":"additional","affiliation":[{"name":"Joint Quantum Institute, National Institute of Standards and Technology and University of Maryland, College Park, MD 20742, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David G.","family":"Cory","sequence":"additional","affiliation":[{"name":"Institute for Quantum Computing, University of Waterloo, Waterloo, ON N2L3G1, Canada."},{"name":"Department of Chemistry, University of Waterloo, Waterloo, ON N2L3G1, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9679-3444","authenticated-orcid":true,"given":"Lisa","family":"DeBeer-Schmitt","sequence":"additional","affiliation":[{"name":"Neutron Scattering Division, Oak Ridge National Laboratory, Oak Ridge, TN 37831, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3795-8445","authenticated-orcid":true,"given":"Michael G.","family":"Huber","sequence":"additional","affiliation":[{"name":"National Institute of Standards and Technology, Gaithersburg, MD 20899, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Connor","family":"Kapahi","sequence":"additional","affiliation":[{"name":"Institute for Quantum Computing, University of Waterloo, Waterloo, ON N2L3G1, Canada."},{"name":"Department of Physics and Astronomy, University of Waterloo, Waterloo, ON N2L3G1, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4594-3403","authenticated-orcid":true,"given":"Dmitry A.","family":"Pushin","sequence":"additional","affiliation":[{"name":"Institute for Quantum Computing, University of Waterloo, Waterloo, ON N2L3G1, Canada."},{"name":"Department of Physics and Astronomy, University of Waterloo, Waterloo, ON N2L3G1, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"221","reference":[{"key":"e_1_3_2_2_2","unstructured":"B.
