Charge dynamics in doped frustrated magnets and quantum spin liquids — •Luke Staszewski and Alexander Wietek — Max Planck Institute for the Physics of Complex Systems, 01187 Dresden, Germany

The advent of recent developments in algorithms, namely finite temperature tensor network related algorithms, has opened the doors to a serious numerical testbed for investigating the plethora of interesting phenomenology in strongly interacting electron systems. This testbed is taking us a step closer to understanding an array of systems displaying unconventional superconductivity as well as helping answer questions about the delicate interplay between magnetic correlations and the onset of superconductivity in such materials. This work looks at how the mobility of holes is affected by various magnetic environments and vice versa in the hope to shed some more light on the nature of the mechanisms at play in the resulting phases that have recently been demonstrated both numerically and experimentally. We focus on the role geometric magnetic frustration plays in leading to both unconventional superconductivity, and exotic magnetic order, such as quantum spin liquids.
