Both effects are different in nature with respect to phase rigidity because of interference of non-time-reversed or time-reversed paths, respectively. Since their occurrence is largely governed by averaging effects, which depend on sample dimensions and the transport regime, we present a systematic study of flux-periodic oscillations of phase-pure zinc-blende GaAs/InAs core/shell nanowires as a function of gate voltage for samples with different contact separation lengths. Our analysis shows that with increasing contact separation length, averaging effects result in gradual reduction of h/e-periodic Aharonov-Bohm-type oscillations, while the h/2e-periodic Altshuler-Aronov-Spivak oscillations and its h/4e-periodic higher harmonics are enhanced. The additional phase rigidity seen in the h/3e-periodic oscillations is attributed to phase rigidity propagating from the neighbouring lower harmonics. Our tight-binding transport simulations on nanowires of different lengths which contain only a few scattering centers confirm the experimental observations regarding the different harmonics and their phase rigidity. Together, our experimental and simulation findings indicate quasi-ballistic transport with persistent Aharonov-Bohm-, and phase-rigid Altshuler-Aronov-Spivak-type oscillations despite few scattering centers."],"keywords":["Physics","Nanowires","Aharonov-Bohm effect","electron interference effects","Altshuler-Aronov-Spivak oscillations"],"citation":[{"@type":"CreativeWork","text":"https://arxiv.org/abs/2606.10788","@id":"https://arxiv.org/abs/2606.10788","identifier":"https://arxiv.org/abs/2606.10788"}],"license":{"@type":"Dataset","text":"CC0","url":"https://creativecommons.org/publicdomain/zero/1.0/"},"includedInDataCatalog":{"@type":"DataCatalog","name":"Jülich DATA","url":"https://data.fz-juelich.de"},"publisher":{"@type":"Organization","name":"Jülich DATA"},"provider":{"@type":"Organization","name":"Jülich DATA"},"funder":[{"@type":"Organization","name":"Deutsche Forschungsgemeinschaft"},{"@type":"Organization","name":"EPSRC"},{"@type":"Organization","name":"Reykjavik University Research Fund"},{"@type":"Organization","name":"JST ASPIRE"}],"distribution":[{"@type":"DataDownload","name":"KWANT_Raw_data_2um.csv","fileFormat":"text/csv","contentSize":699328,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/53718"},{"@type":"DataDownload","name":"KWANT_Raw_data_4um.csv","fileFormat":"text/csv","contentSize":690077,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52827"},{"@type":"DataDownload","name":"KWANT_Raw_data_600nm.csv","fileFormat":"text/csv","contentSize":695879,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52835"},{"@type":"DataDownload","name":"KWANT_Raw_data_S10_a.csv","fileFormat":"text/csv","contentSize":295713,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52834"},{"@type":"DataDownload","name":"KWANT_Raw_data_S10_b.csv","fileFormat":"text/csv","contentSize":295795,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52830"},{"@type":"DataDownload","name":"KWANT_Raw_data_S9_a.csv","fileFormat":"text/csv","contentSize":699549,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52836"},{"@type":"DataDownload","name":"KWANT_Raw_data_S9_b.csv","fileFormat":"text/csv","contentSize":699325,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52833"},{"@type":"DataDownload","name":"Raw_data_SampleA.csv","fileFormat":"text/csv","contentSize":7838014,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52828"},{"@type":"DataDownload","name":"Raw_data_SampleB.csv","fileFormat":"text/csv","contentSize":6321708,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52837"},{"@type":"DataDownload","name":"Raw_data_SampleC.csv","fileFormat":"text/csv","contentSize":7992941,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52831"},{"@type":"DataDownload","name":"Raw_data_SampleD.csv","fileFormat":"text/csv","contentSize":5779565,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52829"},{"@type":"DataDownload","name":"Raw_data_SampleE.csv","fileFormat":"text/csv","contentSize":7941606,"contentUrl":"https://data.fz-juelich.de/api/access/datafile/52832"}]}
