Ultrafast Nonequilibrium Dynamics in Two-dimensional Quantum Spin-Hall Materials
Rajesh K. Malla, Dasol Kim, Dong Eon Kim +2
We develop the theoretical framework of nonequilibrium ultrafast photonics in monolayer quantum spin-Hall insulators supporting a multitude of topological states. In these material…
Strong-field physics in three-dimensional topological insulators
Denitsa Baykusheva, Alexis Chacón, Dasol Kim +3
We investigate theoretically the strong-field regime of light-matter interactions in the topological-insulator class of quantum materials. In particular, we focus on the process of…
White-light-seeded, CEP-stable, 4.5-W, 4-micron KTA parametric amplifier driven by a 1.4-ps Yb:YAG thin disk laser
Tsuneto Kanai, Yeon Lee, Meenkyo Seo +1
We demonstrate a robust, carrier envelope phase (CEP)-stable, potassium titanyl arsenate (KTA)-based optical parametric amplifier (OPA) delivering 6-cycle (79 fs), 3.8-m pulses…
Laser-induced asymmetric faceting and growth of nano-protrusion on a tungsten tip
Hirofumi Yanagisawa, Vahur Zadin, Karsten Kunze +7
Irradiation of a sharp tungsten tip by a femtosecond laser and exposed to a strong DC electric field led to gradual and reproducible surface modifications. By a combination of fiel…
