Ultrafast dynamics in the Lifshitz-type 5 $d$ pyrochlore antiferromagnet Cd $_{2}$ Os $_{2}$ O $_{7}$

Inho Kwak, Min-Cheol Lee, Byung Cheol Park +7

We investigate the ultrafast dynamics of Cd $_{2}$ Os $_{2}$ O $_{7}$ , a prototype material showing a Lifshitz-type transition as a function of temperature. In the paramagnetic metallic state…

Revealing electrically undetectable room temperature surface-mobility of bulky topological insulators by spectroscopic techniques

Bumjoo Lee, Jinsu Kim, Jonghyeon Kim +11

High surface-mobility, which is attributable to topological protection, is a trademark of three-dimensional topological insulators (3DTIs). Exploiting surface-mobility indicates su…
