For the first time, this study shows remarkable differences of intermittent properties between these two fields: (1) The multiorder structure functions of E-field trace fluctuations are more flattened as compared to those of B-field trace fluctuations. (2) The flatness of E-field fluctuations increases monotonically with decreasing scales and eventually exceeds 100 at 1000 Hz, whereas the flatness of B-field fluctuations does not rise so high (less than 100) and tends to fall off at frequencies larger than 1000 Hz. (3) It is revealed that.(p) monotonically and quasi-linearly increases with increasing p for B-field fluctuations even at sub-electron scales. However,.(p) for E-field is concave, turning over at around p.=.2 from increasing to decreasing trends. We quantitatively analyze and find that, with decreasing scales (defined as t), the variance of ln s (defined as.2), where s is the local standard deviation, increases much more slowly than the most probable ln s (defined as mu) decreases (i.e., l t m td d d ln d ln2.) for the B-field case, while the changing rate of the two quantities are of the same order &#8211; l >> t m td d d ln d1 3 ln2 () for the E-field case. These results indicate the distinct intermittency nature between magnetic and electric fields and impose a constraint on theoretical turbulence models.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Zhu, Xingyu; He, Jiansen; Wang, Ying; Sorriso-Valvo, Luca<\/p>\n","protected":false},"featured_media":1294,"comment_status":"closed","ping_status":"open","template":"","meta":[],"product_cat":[574],"product_tag":[747,1579],"class_list":["post-6916","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-journal-articles","product_tag-interplanetary-turbulence","product_tag-planetary-bow-shocks","prodpage-style2"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product\/6916","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/comments?post=6916"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media\/1294"}],"wp:attachment":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media?parent=6916"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_cat?post=6916"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_tag?post=6916"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
