Topology and Magnetism in the Kondo Insulator Phase Diagram
Michael Klett, Seulgi Ok, David Riegler +3
Topological Kondo insulators are a rare example of an interaction-enabled topological phase of matter in three-dimensional crystals - making them an intriguing but also hard case f…
Non-Abelian chiral spin liquid on a simple non-Archimedean lattice
Valerio Peri, Seulgi Ok, Stepan S. Tsirkin +5
We extend the scope of Kitaev spin liquids to non-Archimedean lattices. For the pentaheptite lattice, which results from the proliferation of Stone-Wales defects on the honeycomb l…
Topological many-body scar states in dimensions 1, 2, and 3
Seulgi Ok, Kenny Choo, Christopher Mudry +3
We propose an exact construction for atypical excited states of a class of non-integrable quantum many-body Hamiltonians in one dimension (1D), two dimensions (2D), and three dimen…
Custodial glide symmetry of quantum spin Hall edge modes in WTe monolayer
Seulgi Ok, Lukas Muechler, Domenico Di Sante +3
A monolayer of WTe has been shown to display quantum spin Hall (QSH) edge modes persisting up to 100~K in transport experiments. Based on density-functional theory calculations…
Magnetic Weyl and Dirac Kondo semimetal phases in heterostructures
Seulgi Ok, Markus Legner, Titus Neupert +1
We study a layered three-dimensional heterostructure in which two types of Kondo insulators are stacked alternatingly. One of them is the topological Kondo insulator SmB 6 , the ot…
Effect of Quantum Tunneling on Spin Hall Magnetoresistance
Seulgi Ok, Wei Chen, Manfred Sigrist +1
We present a formalism that simultaneously incorporates the effect of quantum tunneling and spin diffusion on spin Hall magnetoresistance observed in normal metal/ferromagnetic ins…
