Circular dichroism in high-order harmonic generation: Heralding topological phases and transitions in Chern insulators
Alexis Chacón, Dasol Kim, Wei Zhu +10
Topological materials are of interest to both fundamental science and advanced technologies, because topological states are robust with respect to perturbations and dissipation. Ex…

Chiral liquid phase of simple quantum magnets
Zhentao Wang, Adrian E. Feiguin, Wei Zhu +3
We study a quantum phase transition between a quantum paramagnetic state and a magnetically ordered state for a spin XXZ Heisenberg antiferromagnet on a two-dimensional…

Invariance of topological indices under Hilbert space truncation
Zhoushen Huang, W. Zhu, Daniel P. Arovas +2
We show that the topological index of a wavefunction, computed in the space of twisted boundary phases, is preserved under Hilbert space truncation, provided the truncated state re…
