Polarization-driven band topology evolution in twisted MoTe and WSe
Xiao-Wei Zhang, Chong Wang, Xiaoyu Liu +3
Motivated by recent experimental observations of opposite Chern numbers in -type twisted MoTe and WSe homobilayers, we perform large-scale density-functional-theory (DFT…
Gate-tunable antiferromagnetic Chern insulator in twisted bilayer transition metal dichalcogenides
Xiaoyu Liu, Chong Wang, Xiao-Wei Zhang +2
A series of recent experimental works on twisted MoTe homobilayers have unveiled an abundance of exotic states in this system. Valley-polarized quantum anomalous Hall states ha…
Gate-tunable phonon magnetic moment in bilayer graphene
Xiao-Wei Zhang, Yafei Ren, Chong Wang +2
We develop a first-principles quantum scheme to calculate the phonon magnetic moment in solids. As a showcase example, we apply our method to study gated bilayer graphene, a materi…
Signatures of Fractional Quantum Anomalous Hall States in Twisted MoTe2 Bilayer
Jiaqi Cai, Eric Anderson, Chong Wang +13
The interplay between spontaneous symmetry breaking and topology can result in exotic quantum states of matter. A celebrated example is the quantum anomalous Hall (QAH) state, whic…
Fractional Chern Insulator in Twisted Bilayer MoTe
Chong Wang, Xiao-Wei Zhang, Xiaoyu Liu +5
A recent experiment has reported the first observation of a zero-field fractional Chern insulator (FCI) phase in twisted bilayer MoTe moiré superlattices [Nature 622, 63-68 (20…
Kekulé Moiré Superlattices
Yusen Ye, Jimin Qian, Xiao-Wei Zhang +3
Moiré superlattices from stacks of van der Waals materials offer an exciting arena in the fields of condensed matter physics and materials science. Typically, these moiré superlatt…
Tunable phononic coupling in excitonic quantum emitters
Adina Ripin, Ruoming Peng, Xiaowei Zhang +6
Engineering the coupling between fundamental quantum excitations is at the heart of quantum science and technologies. A significant case is the creation of quantum light sources in…
