Infrared Plasmons Propagate through a Hyperbolic Nodal Metal
Yinming Shao, Aaron J. Sternbach, Brian S. Y. Kim +16
Metals are canonical plasmonic media at infrared and optical wavelengths, allowing one to guide and manipulate light at the nano-scale. A special form of optical waveguiding is aff…
Towards compact phase-matched and waveguided nonlinear optics in atomically layered semiconductors
Xinyi Xu, Chiara Trovatello, Fabian Mooshammer +6
Nonlinear frequency conversion provides essential tools for light generation, photon entanglement, and manipulation. Transition metal dichalcogenides (TMDs) possess huge nonlinear…
Spin Wave Generation via Localized Spin-Orbit Torque in an Antiferromagnet-Topological Insulator Heterostructure
Xinyi Xu, Yuriy G. Semenov, Ki Wook Kim
The spin-orbit torque induced by a topological insulator (TI) is theoretically examined for spin wave generation in a neighboring antiferromagnetic thin film. The investigation is…
Nonlinear twistoptics at symmetry-broken interfaces
Kaiyuan Yao, Nathan R. Finney, Jin Zhang +17
Broken symmetries induce strong nonlinear optical responses in materials and at interfaces. Twist angle can give complete control over the presence or lack of inversion symmetry at…
Broadband optical parametric amplification by two-dimensional semiconductors
Chiara Trovatello, Andrea Marini, Xinyi Xu +11
Optical parametric amplification is a second-order nonlinear process whereby an optical signal is amplified by a pump via the generation of an idler field. It is the key ingredient…
Electrical generation and propagation of spin waves in antiferromagnetic thin films
Xinyi Xu, Yuriy G. Semenov, Ki Wook Kim
Electrical generation of THz spin waves is theoretically explored in an antiferromangetic nanostrip via the current-induced spin-orbit torque. The analysis based on micromagnetic s…
Controllable dispersion of domain wall movement in antiferromagnetic thin films at finite temperatures
Yuriy G. Semenov, Xinyi Xu, Ki Wook Kim
The dynamics of a 90 domain wall in an antiferromagnetic nanostrip driven by the current-induced spin-orbital torque are theoretically examined in the presence of random…
Multi-photon Absorption in Optical Pumping of Rubidium
Xinyi Xu
In optical pumping of rubidium, a new kind of absorption occurs with a higher amplitude of radio frequency current. From measurement of the corresponding magnetic field value where…
