More than 30 years after the discovery of high-temperature superconductors, their basic mechanisms are still not fully understood. However, more knowledge would be important to find materials with superconductivity at room temperature that can transport electricity without loss. Scientists at the Max Planck Institute of Quantum Optics are trying to unravel this mystery using a special quantum simulator. Recently, they made a breakthrough: the very first high-resolution photos of single magnetic polarons. They are suspected to be significantly involved in the formation of superconductivity.
