Light-induced ideal Weyl semimetal in HgTe via nonlinear phononics
Dongbin Shin, Angel Rubio, Peizhe Tang
Interactions between light and matter allow the realization of out-of-equilibrium states in quantum solids. In particular, nonlinear phononics is one of the efficient approaches to…
Symmetry-driven anisotropic coupling effect in antiferromagnetic topological insulator: Mechanism for high-Chern-number quantum anomalous Hall state
Yiliang Fan, Huaiqiang Wang, Peizhe Tang +4
Antiferromagnetic (AFM) topological insulators (TIs), which host magnetically gapped Dirac-cone surface states and exhibit many exotic physical phenomena, have attracted great atte…
Floquet engineering of black phosphorus upon below-gap pumping
Shaohua Zhou, Changhua Bao, Benshu Fan +6
Time-periodic light field can dress the electronic states and lead to light-induced emergent properties in quantum materials. While below-gap pumping is regarded favorable for Floq…
Stripe charge order driven manipulation of Majorana bound states in 2M-WS2 topological superconductor
Xuemin Fan, Xiaoqi Sun, Penghao Zhu +8
Majorana bound states (MBSs) are building blocks for topological quantum computing. They can be generated via the combination of electronic topology and superconductivity. To achie…
-Nontrivial Moiré Minibands and Interaction-Driven Quantum Anomalous Hall Insulators in Topological Insulator Based Moiré Heterostructures
Kaijie Yang, Zian Xu, Yanjie Feng +6
We studied electronic band structure and topological property of a topological insulator thin film under a moiré superlattice potential to search for two-dimensional (2D) $\mathbb…
Pseudospin-selective Floquet band engineering in black phosphorus
Shaohua Zhou, Changhua Bao, Benshu Fan +10
Time-periodic light field has emerged as a control knob for manipulating quantum states in solid-state materials, cold atoms and photonic systems via hybridization with photon-dres…
Light-induced emergent phenomena in 2D materials and topological materials
Changhua Bao, Peizhe Tang, Dong Sun +1
Light-matter interaction in 2D and topological materials provides a fascinating control knob for inducing emergent, non-equilibrium properties and achieving new functionalities in…
