About the seminar

Charge density waves (CDWs), electronic states characterised by spontaneously broken translational symmetry, are a common instability in strongly interacting electron systems. They are ubiquitous across condensed matter physics, playing important roles in both quantum Hall systems and unconventional superconductors. In this talk, I will explore CDW orders in rhombohedral multilayer graphene using transport techniques. I show that CDW order in this material is intimately intertwined with the emergence of both superconductivity and the fractional quantum Hall effect. I will discuss the origin of this intertwinement and its implications for understanding Cooper pairing, charge fractionalisation, and the broader emergence of correlated phases at the intersection of strong correlations, topology, and broken symmetries.
