Unoccupied electronic structure and signatures of topological Fermi arcs in the Weyl semimetal candidate MoWTe
Ilya Belopolski, Su-Yang Xu, Yukiaki Ishida +30
Weyl semimetals have sparked intense research interest, but experimental work has been limited to the TaAs family of compounds. Recently, a number of theoretical works have predict…
Quasi-particles ultrafastly releasing kink bosons to form Fermi arcs in a cuprate superconductor
Y. Ishida, T. Saitoh, T. Mochiku +3
In a conventional framework, superconductivity is lost at a critical temperature (T_c) because, at higher temperatures, gluing bosons can no longer bind two electrons into a Cooper…
Electronic structure and relaxation dynamics in a superconducting topological material
Madhab Neupane, Yukiaki Ishida, Raman Sankar +9
Topological superconductors host new states of quantum matter which show a pairing gap in the bulk and gapless surface states providing a platform to realize Majorana fermions. Rec…
Quadratic Fermi Node in a 3D Strongly Correlated Semimetal
Takeshi Kondo, M. Nakayama, R. Chen +18
Strong spin-orbit coupling fosters exotic electronic states such as topological insulators and superconductors, but the combination of strong spin-orbit and strong electron-electro…
Gigantic surface life-time of an intrinsic topological insulator revealed via time-resolved (pump-probe) ARPES
Madhab Neupane, Su-Yang Xu, Yukiaki Ishida +11
The interaction between light and novel two-dimensional electronic states holds promise to realize new fundamental physics and optical devices. Here, we use pump-probe photoemissio…
Emergent photovoltage on SmB6 surface upon bulk-gap evolution revealed by pump-and-probe photoemission spectroscopy
Y. Ishida, T. Otsu, T. Shimada +5
Recent studies suggest that an exemplary Kondo insulator SmB6 belongs to a new class of topological insulators (TIs), in which non-trivial spin-polarized metallic states emerge on…
