Quantum Metric Length as a Fundamental Length Scale in Disordered Flat Band Materials
Chun Wang Chau, Tian Xiang, Shuai A. Chen +1
Our previous understanding of electronic transport in disordered systems was based on the assumption that there is a finite Fermi velocity for the relevant electrons. The Fermi vel…

Disorder-induced diffusion transport in flat-band systems with quantum metric
Chun Wang Chau, Tian Xiang, Shuai A. Chen +1
Our previous understanding of transport in disordered system depends on the assumption that there is a well-defined Fermi velocity. The Fermi velocity determines important length s…
