scientist can now reliably create a strange quantum object called a knowledge domain wall . The discovery could lead to newfangled quantum technology and to a better sympathy of quantum corpuscle in general .
Domain bulwark form when groups ofatomsat very low temperatures segregate into different clumps , or " domains . " Between those domains form a " wall " that behaves so otherwise from the atoms themselves that scientist consider it an independent quantum object .
Researchers discovered how to create a quantum phenomenon known as a “domain wall,” shown in this image as the lighter line between two groups of atoms. (Image adapted and color added from experiment data.)
scientist have witnessed domain rampart before , but this is the first time that a squad has developed a reliable elbow room to create and study them . The researchers simulated aBose - Einstein condensate , astate of matterwhere the element particles are cool to the point that they distil into a undivided quantum object . By tweaking sure circumstance , the squad was able to make atoms in the condensate freestanding into high- and broken - concentration domains with a demesne wall in between them . That wall acted like a completely disjoined object . For example , campaign the atoms in one counseling guide the rampart to move in the opposite direction .

" It ’s kind of like a sand dune in the desert — it ’s made up of Baroness Dudevant , but the dune play like an object that deport other than from case-by-case food grain of sand , " first generator and doctoral student Kai - Xuan Yaosaid in a command .

That puts domain wall in the class of " emerging phenomenon , " or single in which the particles in an object behave other than together than they do on their own . Studying emergent phenomenon can aid drop light on other event that involve many particles acting in unison — for lesson , in the former universe , when particles first clumped together to organise stars and extragalactic nebula .
The ability to mother quantum objects like these could also assist in the evolution of young technology .
“ It can be used to make a more rich way to salt away quantum info or enable new role in materials , " Colorado - writer Cheng Chin said in the statement . " But before we can rule that out , the first step is to understand how to control them . "
