Ultrafast switching of topological invariants by light-driven strain

Autor: Park, Tae Gwan, Baek, Seungil, Park, Junho, Shin, Eui-Cheol, Na, Hong Ryeol, Oh, Eon-Taek, Chun, Seung-Hyun, Kim, Yong-Hyun, Lee, Sunghun, Rotermund, Fabian

Reversible control of the topological invariants from nontrivial to trivial states has fundamental implications for quantum information processors and spintronics, by realizing of an on/off switch for robust and dissipationless spin-current. Although

Ultrafast acousto-optic modulation at the near-infrared spectral range by interlayer vibrations

Autor: Park Tae Gwan, Kim Chaeyoon, Oh Eon-Taek, Na Hong Ryeol, Chun Seung-Hyun, Lee Sunghun, Rotermund Fabian

Publikováno v: Nanophotonics, Vol 13, Iss 7, Pp 1059-1068 (2024)

The acousto-optic modulation over a broad near-infrared (NIR) spectrum with high speed, excellent integrability, and relatively simple scheme is crucial for the application of next-generation opto-electronic and photonic devices. This study aims to e

Electronic structure and charge-density wave transition in monolayer VS_{2}

Autor: Kim, Hyuk Jin, Choi, Byoung Ki, Lee, In Hak, Kim, Min Jay, Chun, Seung-Hyun, Jozwiak, Chris, Bostwick, Aaron, Rotenberg, Eli, Chang, Young Jun

Vanadium disulfide (VS_{2}) attracts elevated interests for its charge-density wave (CDW) phase transition, ferromagnetism, and catalytic reactivity, but the electronic structure of monolayer has not been well understood yet. Here we report synthesis

Skyrmion phase in MnSi on sapphire grown by a conventional sputtering

Autor: Choi, Won-Young, Bang, Hyun-Woo, Chun, Seung-Hyun, Lee, Sunghun, Jung, Myung-Hwa

Topologically protected chiral skyrmion is an intriguing spin texture, which has attracted much attention because of fundamental research and future spintronic applications. MnSi with the non-centrosymmetric structure is well-known material hosting s
