Shadow-Free Scattering with Complex Frequency Excitations
Vitali Kozlov, Wei Wang, Seunghwi Kim +2
The optical theorem dictates that the wave scattering of an object in the forward direction is proportional to the total power extinguished from the excitation. For passive objects…
Multimodal Terahertz Spectroscopy of the Pairing Symmetry and Normal-State Pseudogap in (La,Pr)NiO Films
Shuxiang Xu, Guangdi Zhou, Hao Wang +11
The discovery of ambient-pressure superconductivity in compressively strained (La,Pr)NiO thin films has intensified efforts to identify the pairing mechanism. However,…
Band modulations and topological transitions in a one-dimensional periodic bead-on-string chain
Haocong Pan, Wei Wang, Chunling Liu
We study band modulations and topological transitions in a one-dimensional periodic bead-on-string chain. Using an exact transfer-matrix formulation of the wave equation with perio…
Optical signatures of -1/3 fractional quantum anomalous Hall state in twisted MoTe2
Haiyang Pan, Shunshun Yang, Yuzhu Wang +9
The discovery of fractional charge excitations in new platforms offers crucial insights into strongly correlated quantum phases. While a range of fractional quantum anomalous Hall…
On-chip electrically reconfigurable octave-bandwidth optical amplification from visible to near-infrared
Guanyu Han, Wenjun Deng, Yu Wang +8
Achieving broadband on-chip optical amplification spanning the visible and near-infrared (NIR) can enable diverse quantum sensing, metrology, and classical communication applicatio…
