Valley Order in Moiré Topological Insulators
Bo Zou, Anzhuoer Li, Allan H. MacDonald
Moiré materials with opposite non-zero miniband Chern numbers in time-reversal-partner valleys are two-dimensional topological insulators at band filling . We explore the poss…

Competition between excitonic insulators and quantum Hall states in correlated electron-hole bilayers
Ruishi Qi, Qize Li, Zuocheng Zhang +11
Excitonic insulators represent a unique quantum phase of matter, providing a rich ground for studying exotic quantum bosonic states. Strongly coupled electron-hole bilayers, which…

Quantum oscillations in a dipolar excitonic insulator
Phuong X. Nguyen, Raghav Chaturvedi, Bo Zou +5
Quantum oscillations in magnetization or resistivity are a defining feature of metals subject to an external magnetic field. The phenomenon is generally not expected in insulators…
