Non-Equilibrium Orbital Transport in Terahertz Optorbitronics
Sobhan Subhra Mishra, Ranjan Singh
Modern information technologies rely on controlling the flow of electrons through their charge and spin. A rapidly emerging alternative is to use the orbital motion of electrons, t…
Complex Refractive Index Extraction for Spintronic Terahertz Emitter Analysis
Yingshu Yang, Keynesh Dongol, Stefano Dal Forno +7
Spintronic terahertz emitters (STEs) generate broadband terahertz (THz) radiation, which is essential for spectroscopy, imaging, and communication. The performances and the essenti…
Electric-field Control of Giant Ferronics
Baolong Zhang, Ruihuan Duan, Sobhan Subhra Mishra +8
Ferrons are quantum excitations of electric polarization in ferroelectrics and electric analogues of magnons but have lacked direct experimental verification at room temperature. W…
Electrically tunable Floquet Weyl photon emission from Dirac semimetal Cd3As2
Sobhan Subhra Mishra, Thomas CaiWei Tan, Manoj Gupta +2
The ability to optically engineer the Dirac band and electrically control the Fermi level in two-dimensional (2D) Dirac systems, such as graphene, has significantly advanced quantu…
Terahertz Cavity Phonon Polaritons in Lead Telluride in the Deep-Strong Coupling Regime
Andrey Baydin, Manukumara Manjappa, Sobhan Subhra Mishra +9
Lead telluride is an important thermoelectric material due to its large Seebeck coefficient combined with its unusually low thermal conductivity that is related to the strong anhar…
