Johan Chang: New publication in Nature Physics
on the impact of low-energy spin fluctuations on the strange metal in a cuprate superconductor.
It was investigate how the strange metal phase of La2-xSrxCuO4 is impacted by a field-induced glassy antiferromagnetic state. Strange metals exhibit unusual properties such as a resistivity that scales linearly with temperature. It was found that the transport properties of the strange metal phase are closely linked to low-energy magnetic fluctuations that persist at
the lowest temperatures.
