Broad-band THz emission by Spin-to-Charge Conversion in Topological Material -- Ferromagnet Heterostructures
Xingyue Han, Xiong Yao, Tilak Ram Thapaliya +10
Terahertz spintronic devices combine ultrafast operation with low power consumption, making them strong candidates for next-generation memory technologies. In this study, we use ti…
Large Topological Magnetic Optical Effects and Imaging of Antiferromagnetic Octupole Domains of an Altermagnet-like Weyl Semimetal
Xingyue Han, Xiaoran Liu, Mikhail Kareev +2
Pyrochlore iridates have attracted significant interest due to their complex phase behavior arising from the interplay among electron correlations, quantum metric in flat bands, ge…
Magneto-optical effects of an artificially-layered ferromagnetic topological insulator with T of 160 K
Xingyue Han, Hee Taek Yi, Seongshik Oh +1
Magnetic topological insulator is a fertile platform to study the interplay between magnetism and topology. The unique electronic band structure can induce exotic transport and opt…
A new type of cyclotron resonance from charge-impurity scattering in the bulk-insulating BiSe thin films
Xingyue Han, Maryam Salehi, Seongshik Oh +1
This work focuses on the low frequency Drude response of bulk-insulating topological insulator BiSe films. The frequency and field dependence of the mobility and carrier de…
Observation of the superconducting proximity effect from surface states in SmB/YB thin film heterostructures via terahertz spectroscopy
Jonathan Stensberg, Xingyue Han, Seunghun Lee +5
The AC conduction of epitaxially-grown SmB thin films and superconducting heterostructures of SmB/YB are investigated via time domain terahertz spectroscopy. A two-chan…
Giant intrinsic anomalous terahertz Faraday rotation in the magnetic Weyl semimetal CoMnGa at room temperature
Xingyue Han, Anastasios Markou, Jonathan Stensberg +3
We report measurement of terahertz anomalous Hall conductivity and Faraday rotation in the magnetic Weyl semimetal CoMnGa thin films as a function of the magnetic field, temper…
Kondo physics in antiferromagnetic Weyl semimetal Mn3+xSn1-x films
Durga Khadka, T. R. Thapaliya, Sebastian Hurtado Parra +9
Topology and strong electron correlations are crucial ingredients in emerging quantum materials, yet their intersection in experimental systems has been relatively limited to date.…
Electron-Hole Asymmetry of Surface States in Topological Insulator Sb2Te3 Thin Films Revealed by Magneto-Infrared Spectroscopy
Yuxuan Jiang, Mahmoud M. Asmar, Xingyue Han +7
When surface states (SSs) form in topological insulators (TIs), they inherit the properties of bulk bands, including the electron-hole (e-h) asymmetry but with much more profound i…
