Topological Kondo Insulator from Spin Loop Currents
Andreas Gleis, Kevin Lucht, Po-Jui Chen +3
We demonstrate that interacting electrons in AB-stacked realize a topological Kondo insulator at hole filling per moiré unit cell. In the p…

A higher dimensional generalization of the Kitaev spin liquid
Po-Jui Chen, Piers Coleman
We construct an exactly solvable model of a four-dimensional Kitaev spin liquid. The lattice structure is orthorhombic and each unit-cell contains six sublattice degrees of freedom…

A Landau Theory for Pair Density Modulation in Fe(Te,Se) flakes
Po-Jui Chen, Piers Coleman
Motivated by recent scanning tunneling microscopy (STM) experiments reporting a pair-density modulation (PDM) in flakes of FeTeSe, we develop a Landau theory…
