Associate Professor Mazhar Ali and his research group at TU Delft have discovered one-way superconductivity without magnetic fields, something that was thought to be impossible ever since its discovery in 1911 \u2013 up till now. The discovery, which was published in Nature<\/a> yesterday, makes use of 2D quantum materials and paves the way towards superconducting computing, so TU Delft in a press release<\/a>. Superconductors can make electronics hundreds of times faster, all with zero energy loss. Ali: \u201cIf the 20th century was the century of semi-conductors, the 21st can become the century of the superconductor.\u201d<\/p>\n\n\n\n

During the 20th<\/sup> century many scientists, including Nobel Prize winners, have puzzled over the nature of superconductivity, which was discovered by Dutch physicist Kamerlingh Onnes in 1911 (read more about this in the frame below<\/em>). In superconductors, a current goes through a wire without any resistance, which means inhibiting this current or even blocking it is hardly possible \u2013 let alone getting the current to flow only one way and not the other. <\/p>\n\n\n\n

That Dr. Heng Wu and Dr. Yaojia Wang, the lead researchers in Ali\u2019s group who carried out this study, managed to make superconducting one-directional \u2013 necessary for computing \u2013 is remarkable: one can compare it to inventing a special type of ice that gives you zero friction when skating one way, but insurmountable friction the other way. <\/a>Artist Ella Marushenko\u2019s interpretation of the Josephson Diode effect. The image shows a computer chip made from a few layers of atoms (blue and white spheres) comprising the Josephson Diode. The green pairs of spheres represent superconducting pairs of electrons moving in one direction, while the orange spheres represent normal conducting single electrons moving in the opposite direction across the Josephson Diode.<\/p>\n\n\n\n

Superconductor: super-fast, super-green<\/h3>\n\n\n\n

The advantages of applying superconductors to electronics are twofold. Superconductors can make electronics hundreds of times faster, and implementing superconductors into our daily lives would make IT much greener: if you were to spin a superconducting wire from here to the moon, it would transport the energy without any loss. For instance, the use of superconductors instead of regular semi-conductors might save up to 10 percent of all western energy reserves according to NWO.

On May 18th<\/sup> \u2013 19th<\/sup>, Associate Professor Mazhar Ali and his collaborators Prof. Valla Fatemi (Cornell University) and Dr. Heng Wu (TU Delft<\/a>) are hosting a \u201cSuperconducting Diode Effects Workshop<\/a>\u201d on the Virtual Science Forum, in which 12 international experts in the field will be giving recorded talks online (to be published on YouTube) about the current state of the field as well as future research and development directions.  <\/p>\n","protected":false},"author":1760,"featured_media":371829,"template":"","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[8553],"tags":[69427,30700],"location":[6763],"internal_archives":[],"class_list":["post-371825","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-digital","tag-computers-2","tag-superconductors","location-netherlands"],"blocksy_meta":[],"acf":[],"featured_img":false,"coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/arnoud-cornelissen\/","display_name":"Arnoud Cornelissen"},"relative_dates":{"created":"Posted 4 years ago","modified":"Updated 4 years ago"},"absolute_dates":{"created":"Posted on May 4, 2022","modified":"Updated on May 4, 2022"},"absolute_dates_time":{"created":"Posted on May 4, 2022 10:52 am","modified":"Updated on May 4, 2022 10:52 am"},"featured_img_caption":"","tax_additional":{"category":{"linked":["Digital<\/a>"],"unlinked":["Digital<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["computers<\/a>","superconductors<\/a>"],"unlinked":["computers<\/span>","superconductors<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":["pll_62723c78350d0<\/a>"],"unlinked":["pll_62723c78350d0<\/span>"],"slug":"post_translations","name":""},"location":{"linked":["Netherlands<\/a>"],"unlinked":["Netherlands<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/371825","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/1760"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=371825"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=371825"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=371825"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=371825"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=371825"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
