Terahertz Metamaterial Renormalization of Superconducting Josephson Plasmons in LaSrCuO
Kelson Kaj, Ian Hammock, Chunxu Chen +8
We investigate light-matter coupling in the cuprate superconductor LaSrCu0 (LSCO), accomplished by adhering metamaterial resonator arrays (MRAs) to a c-axis o…
Conformal Metamaterials with Active Tunability and Self-adaptivity for Magnetic Resonance Imaging
Ke Wu, Xia Zhu, Xiaoguang Zhao +2
Ongoing effort has been devoted to applying metamaterials to boost the imaging performance of magnetic resonance imaging owing to their unique capacity for electromagnetic field co…
Complementary Vanadium Dioxide Metamaterials with Enhanced Modulation Amplitude at Terahertz Frequencies
Yuwei Huang, Xuefei Wu, Jacob Schalch +8
One route to create tunable metamaterials is through integration with "on-demand" dynamic quantum materials, such as vanadium dioxide (VO2). This enables new modalities to create h…
Auxetics-Inspired Tunable Metamaterials for Magnetic Resonance Imaging
Ke Wu, Xiaoguang Zhao, Stephan W. Anderson +1
Auxetics refers to structures or materials with a negative Poisson's ratio, thereby capable of exhibiting counter-intuitive behaviors. Herein, auxetic structures are exploited to d…
Multi-messenger nano-probes of hidden magnetism in a strained manganite
A. S. McLeod, J. Zhang, M. Q. Gu +9
The ground state properties of correlated electron systems can be extraordinarily sensitive to external stimuli, such as temperature, strain, and electromagnetic fields, offering a…

Terahertz Saturable Absorption in Superconducting Metamaterials
George R. Keiser, Jingdi Zhang, Xiaoguang Zhao +2
We present a superconducting metamaterial saturable absorber at terahertz frequencies. The absorber consists of an array of split ring resonators (SRRs) etched from a 100nm YBaCu3O…
Terahertz radiation-induced sub-cycle field electron emission across a split-gap dipole antenna
Jingdi Zhang, Xiaoguang Zhao, Kebin Fan +5
We use intense terahertz pulses to excite the resonant mode (0.6 THz) of a micro-fabricated dipole antenna with a vacuum gap. The dipole antenna structure enhances the peak amplitu…
Nonlinear terahertz devices utilizing semiconducting plasmonic metamaterials
