Dynamical torques from Shiba states in -wave superconductors
Archana Mishra, So Takei, Pascal Simon +1
Magnetic impurities inserted in a -wave superconductor give rise to spin-polarized in-gap states called Shiba states. We study the back-action of these induced states on the dyn…

Moon Jip Park, GiBaik Sim, Min Yong Jeong +3
Lacunar spinel GaTaSe is a unique example of spin-orbit coupled Mott insulator described by molecular states. It becomes superconducting at T=5…
Emergent chiral spin ordering and anomalous Hall effect of kagome lattice at 1/3 filling
Hee Seung Kim, Archana Mishra, SungBin Lee
The study of electronic and magnetic properties of kagome lattice has been an active research area searching for topological phases of matters. In particular, the kagome system wit…
Multipolar superconductivity in Luttinger semimetals
GiBaik Sim, Archana Mishra, Moon Jip Park +3
Topological superconductivity in multiband systems has received much attention due to a variety of possible exotic superconducting order parameters as well as non-trivial bulk and…
Stacking sensitive topological phases in a bilayer Kane-Mele-Hubbard model at quarter filling
