Such electron fluids are ideal to find new behaviours of materials in which <a href=\"https:\/\/phys.org\/tags\/electron-electron+interactions\/\" rel=\"tag\" class=\"\">electron-electron interactions<\/a> are particularly strong. The problem is that most materials are rarely pure enough to allow electrons to enter the viscous regime. This is because they contain many impurities off which electrons can scatter before they have time to interact with each other and organise a viscous flow.<\/p>\n<p><!-- Link: <a href=\"https:\/\/phys.org\/news\/2019-02-hall-effect-viscous-graphene.html\">https:\/\/phys.org\/news\/2019&#45;02-hall-effect-viscous-graphene.html<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at The University of Manchester in the UK have discovered that the Hall effect\u2014a phenomenon well known for more than a century\u2014is no longer as universal as it was thought to be.
