Condensed Matter Journal Club - "The Higher-Order Topological Semimetals: Dirac, Weyl and superconductivity"
(sign-up)Sayed Ali Akbar Ghorashi
|Sponsor:||CM Journal Club|
In this talk, I will discuss some aspects of higher-order topological semimetals. In particular, starting from a higher-order Dirac semimetal, I will first discuss the effect of superconducting instability  and obtain two classes of higher-order topological superconductors. Next, I will show various ways of getting higher-order Weyl semimetals and present some of their interesting properties .
