Topological superconductivity from transverse optical phonons in oxide heterostructures
Minseong Lee, Hyun-Jae Lee, Jun Hee Lee +1
A topological superconductor features at its boundaries and vortices Majorana fermions, which are potentially applicable for topological quantum computations. The scarcity of the k…

First-principles approach to the dynamic magnetoelectric couplings in BiFeO
Jun Hee Lee, Istvan Kézsmáki, Randy S. Fishman
Despite its great technological importance, the magnetoelectric (ME) couplings in \BF are barely understood. By using a first-principles approach, we uncover the {\it dynamic} ME c…

Huge Spin-Driven Polarizations at Room-Temperature in bulk BiFeO3
Jun Hee Lee, Randy S. Fishman
The spin-driven polarizations of type-I multiferroics are veiled by the preexisting ferroelectric (FE) polarization. Using first-principles calculations combined with a spin model,…
