SU(4) Kondo Lattice in Semiconductor Moiré Materials
Sunghoon Kim
Motivated by recent advances in transition metal dichalcogenide (TMD) moiré materials, we propose TMD moiré multilayers as a platform for realizing an approximately SU(4)-symmetr…

Homogenization of an obstacle problem with highly oscillating coefficients and obstacles
Sunghoon Kim, Ki-Ahm Lee, Se-Chan Lee +1
We develop the viscosity method for the homogenization of an obstacle problem with highly oscillating obstacles. The associated operator, in non-divergence form, is linear and elli…
