Interfacial spintronic THz emission
Piyush Agarwal, Rohit Medwal, Keynesh Dongol +5
The broken inversion symmetry at the ferromagnet (FM)/heavy-metal (HM) interface leads to spin-dependent degeneracy of the energy band, forming spin-polarized surface states. As a…
Secondary spin current driven efficient THz spintronic emitters
Piyush Agarwal, Yingshu Yang, Rohit Medwal +4
Femtosecond laser-induced photoexcitation of ferromagnet (FM)/heavy metal (HM) heterostructures have attracted attention by emitting broadband terahertz frequencies. The phenomenon…
The Elusive High-Tc Superinductor
Yogesh Kumar Srivastava, Manoj Gupta, Manukumara Manjappa +3
Ginzburg-Landau (GL) parameters formed the basis for Abrikosov discovery of the quantum vortex of a supercurrent in type-II superconductor with a normal core of size , the super…
Terahertz sensing of highly absorptive water-methanol mixtures with multiple resonances in metamaterials
Min Chen, Leena Singh, Ningning Xu +3
Ultrasensitive terahertz sensing of highly absorptive aqueous solutions remains challenging due to strong absorption of water in the terahertz regime. Here, we experimentally demon…
Ultra-high terahertz index in deep subwavelength coupled bi-layer free-standing flexible metamaterials
Leena Singh, Ranjan Singh, Weili Zhang
We report extensive enhancement in the refractive index of artificially designed metamaterials by exploiting the deep subwavelength coupling in a free-standing, thin-film metal-die…
Temporal Loss Boundary Engineered Photonic Cavity
Longqing Cong, Jiaguang Han, Weili Zhang +1
Losses are ubiquitous and unavoidable in nature inhibiting the performance of most optical processes. Manipulating losses to adjust the dissipation of photons is analogous to braki…
