Quantum twisting microscope reveals electron-electron interactions in graphene at room temperature

An international team of researchers built a highly sensitive quantum microscope and used it to directly observe, for the first time at room temperature, how electrons subtly interact with each other in graphene—confirming a decades-old theoretical prediction with remarkable precision. The research is published in the journal Nano Letters. The team was led by Dmitri Efetov, Professor of Experimental Solid State Physics at LMU München's Faculty of Physics and MCQST co-coordinator for Research Area Quantum Matter.
