Photoswitchable exceptional points derived from bound states in the continuum
Lei Wang, Hang Liu, Junwei Liu +11
Bound states in the continuum (BICs) and exceptional points (EPs), as two distinct physical singularities represented by complex frequencies in non-Hermitian systems, have garnered…
Frequency-selective terahertz wave amplification by a time-boundary-engineered Huygens metasurface
Fu Deng, Fengjie Zhu, Xiaoyue Zhou +7
Ultrafast manipulation of optical resonance can establish the time-boundary effect in time-variant media leading to a new degree of freedom for coherent control of electromagnetic…
Physics-informed Inverse Design of Multi-bit Programmable Metasurfaces
Yucheng Xu, Jia-Qi Yang, Kebin Fan +8
Emerging reconfigurable metasurfaces offer various possibilities in programmatically manipulating electromagnetic waves across spatial, spectral, and temporal domains, showcasing g…
Manipulating THz Spin Current Dynamics by the Dzyaloshinskii-Moriya Interaction in Antiferromagnetic Hematite
Hongsong Qiu, Tom Sebastian Seifert, Lin Huang +12
An important vision of modern magnetic research is to use antiferromagnets as controllable and active ultrafast components in spintronic devices. Hematite is a promising model mate…
High-efficiency spontaneous terahertz emission from electrically-excited plasmons in AlGaN/GaN two-dimensional electron gas
Hua Qin, Yao Yu, Jiandong Sun +16
The advance of terahertz science and technology yet lays wait for the breakthrough in high-efficiency and high-power solid-state terahertz sources applicable at room temperature. P…
Terahertz Nonlinear Superconducting Metamaterials
Caihong Zhang, Biaobing Jin, Jiaguang Han +7
We investigate the nonlinear effect of a planar superconducting metamaterial made from niobium nitride (NbN) at terahertz frequencies. As the variation of the incident intense tera…
