Topological Enhancement of Nonlinear Transports in Unconventional Point-Node Semimetals
Junyeong Ahn
The topological singularity of the Bloch states close to the Fermi level significantly enhances nonlinear electric responses in topological semimetals. Here, we systematically char…

Topological Circular Dichroism in Chiral Multifold Semimetals
Junyeong Ahn, Barun Ghosh
Uncovering the physical contents of the nontrivial topology of quantum states is a critical problem in condensed matter physics. Here, we study the topological circular dichroism i…
