In this study, we explore the capabilities of anisotropic temporal slabs, which rely on abrupt changes in time from isotropic to anisotropic response (and vice versa). Our findings show that these platforms can effectively manipulate the wave\u2010spin dimension, allowing for a range of intriguing spin\u2010controlled photonic operations. We demonstrate these capabilities through examples of spin\u2010dependent analog computing and spin\u2013orbit interaction effects for vortex generation. These results provide new insights into the field of temporal metamaterials, and suggest potential applications in communications, optical processing and quantum technologies.<\/jats:p>","DOI":"10.1515\/nanoph-2022-0809","type":"journal-article","created":{"date-parts":[[2023,2,21]],"date-time":"2023-02-21T15:50:48Z","timestamp":1676994648000},"page":"2891-2904","source":"Crossref","is-referenced-by-count":18,"title":["Spin\u2010controlled photonics via temporal anisotropy"],"prefix":"10.1002","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0047-5228","authenticated-orcid":false,"given":"Carlo","family":"Rizza","sequence":"first","affiliation":[{"name":"Department of Physical and Chemical Sciences University of L\u2019Aquila L\u2019Aquila I\u201067100 Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Castaldi","sequence":"additional","affiliation":[{"name":"Department of Engineering, Fields &amp; Waves Lab University of Sannio Benevento I\u201082100 Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4796-3600","authenticated-orcid":false,"given":"Vincenzo","family":"Galdi","sequence":"additional","affiliation":[{"name":"Department of Engineering, Fields &amp; Waves Lab University of Sannio Benevento I\u201082100 Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,2,21]]},"reference":[{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1515\/nanoph\u20102020\u20100414"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/tap.2019.2944225"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/tap.2019.2944216"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/tmtt.1958.1124533"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/tmtt.1961.1125340"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/tap.1970.1139657"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/tap.1971.1139931"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1103\/physrevlett.109.160401"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1088\/1361\u20106633\/aa8b38"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1038\/lsa.2014.36"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.aae0330"},{"key":"e_1_2_8_13_2","doi-asserted-by":"publisher","DOI":"10.1109\/tmtt.2019.2915074"},{"key":"e_1_2_8_14_2","doi-asserted-by":"publisher","DOI":"10.1364\/optica.374788"},{"key":"e_1_2_8_15_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467\u2010020\u201015682\u20102"},{"key":"e_1_2_8_16_2","unstructured":"Z.HayranandF.Monticone \u201cChallenging fundamental limitations in electromagnetics with time\u2010varying systems \u201darXiv:2205.07142 2022."},{"key":"e_1_2_8_17_2","doi-asserted-by":"publisher","DOI":"10.1364\/ol.39.000574"},{"key":"e_1_2_8_18_2","doi-asserted-by":"publisher","DOI":"10.1103\/physrevb.106.094312"},{"key":"e_1_2_8_19_2","doi-asserted-by":"publisher","DOI":"10.1364\/ol.402856"},{"key":"e_1_2_8_20_2","doi-asserted-by":"publisher","DOI":"10.1103\/physrevlett.125.127403"},{"key":"e_1_2_8_21_2","doi-asserted-by":"publisher","DOI":"10.1103\/physrevapplied.12.024026"},{"key":"e_1_2_8_22_2","doi-asserted-by":"publisher","DOI":"10.1063\/5.0042567"},{"key":"e_1_2_8_23_2","doi-asserted-by":"publisher","DOI":"10.1515\/nanoph\u20102022\u20100338"},{"key":"e_1_2_8_24_2","doi-asserted-by":"publisher","DOI":"10.1103\/physreva.93.063813"},{"key":"e_1_2_8_25_2","doi-asserted-by":"publisher","DOI":"10.1364\/optica.5.001390"},{"key":"e_1_2_8_26_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.abo3324"},{"key":"e_1_2_8_27_2","doi-asserted-by":"publisher","DOI":"10.1103\/physrevlett.121.204301"},{"key":"e_1_2_8_28_2","doi-asserted-by":"publisher","DOI":"10.1364\/optica.381175"},{"key":"e_1_2_8_29_2","doi-asserted-by":"publisher","DOI":"10.1515\/nanoph\u20102021\u20100231"},{"key":"e_1_2_8_30_2","doi-asserted-by":"publisher","DOI":"10.1515\/nanoph\u20102022\u20100200"},{"key":"e_1_2_8_31_2","doi-asserted-by":"publisher","DOI":"10.1364\/optica.408399"},{"key":"e_1_2_8_32_2","doi-asserted-by":"publisher","DOI":"10.1117\/1.ap.4.1.014002"},{"key":"e_1_2_8_33_2","doi-asserted-by":"publisher","DOI":"10.1364\/ome.471007"},{"key":"e_1_2_8_34_2","doi-asserted-by":"publisher","DOI":"10.1364\/ome.471672"},{"key":"e_1_2_8_35_2","doi-asserted-by":"crossref","unstructured":"H.Moussa G.Xu S.Yin E.Galiffi Y.Radi andA.Al\u00f9 \u201cObservation of temporal reflections and broadband frequency translations at photonic time\u2010interfaces \u201darXiv:2208.07236 2022.","DOI":"10.1038\/s41567-023-01975-y"},{"key":"e_1_2_8_36_2","doi-asserted-by":"crossref","unstructured":"X.Wang M.
