Quantum critical metals and loss of quasiparticles
Haoyu Hu, Lei Chen, Qimiao Si
Strange metals develop near quantum critical points in a variety of strongly correlated systems. Some of the issues that are central to the field include how the quantum-critical s…

Metallic quantum criticality enabled by flat bands in a kagome lattice
Lei Chen, Fang Xie, Shouvik Sur +4
Strange metals arise in a variety of platforms for strongly correlated electrons, ranging from the cuprates, heavy fermions to flat band systems. Motivated by recent experiments in…

Shot noise and universal Fano factor as characterization of strongly correlated metals
Yiming Wang, Chandan Setty, Shouvik Sur +4
Shot noise measures out-of-equilibrium current fluctuations and is a powerful tool to probe the nature of current-carrying excitations in quantum systems. Recent shot noise measure…
