A universal description of Mott insulators: Characterizing quantum phases beyond broken symmetries
Matheus de Sousa, Zhiyu Fan, Wei Ku
Using Mott insulators as a prototypical example, we demonstrate a dynamics-based characterization of quantum phases of matter through a general N-body renormalization group framewo…

Magnetoelectric torque and edge currents in spin-orbit coupled graphene nanoribbons
Matheus S. M. de Sousa, Manfred Sigrist, Wei Chen
For graphene nanoribbons with Rashba spin-orbit coupling, the peculiar magnetic response due to the presence of a magnetization and geometric confinement are analyzed within a tigh…
