Realization of Arbitrary Gauge Fields via Symmetry-Protected Zero Modes
J. X. Dai, Bingbing Wang, Jiangzi Chen +2
Gauge fields are fundamental to modern physics, but prescribed gauge configurations are often difficult to implement in artificial systems. Here, we present a general scheme for re…
Topological antilaser
Rui-Chang Shen, Chunquan Peng, Bingbing Wang +6
Coherent perfect absorption (CPA)-the time-reversed operation of lasing at threshold-relies on finely tuned interference and is intrinsically fragile to disorder and structural imp…
Pressure-Tunable Generalized Wigner Crystal and Fractional Chern Insulator in twisted MoTe
Bingbing Wang, Junxi Yu, Cheng-Cheng Liu
Due to the forming of low-energy flat bands, the moiré superlattices of the transition metal dichalcogenides are fascinating platforms for studying novel correlated states when su…
Spontaneous Fully Compensated Ferrimagnetism
Bingbing Wang, Yongpan Li, Yichen Liu +1
We propose a general mechanism for the spontaneous emergence of filling-enforced fully compensated ferrimagnetism (fFIM), characterized by zero net magnetization yet ferromagnetic-…
Relaxation and Its Effects on Electronic Structure in Twisted Systems: An Analytical Perspective
Junxi Yu, Bingbing Wang, Cheng-Cheng Liu
Lattice relaxation profoundly reshapes electronic structures in twisted materials. Prevailing treatments, however, typically rely on large-scale density functional theory (DFT), wh…
