Over the past decade, the interplay between symmetry and topology in condensed matter physics has not only deepened our understanding of matter by prompting a conceptual revolution in classifying all phases of matter, but it has also led to tremendous progress in finding new materials with low...
We study the effects of electron-electron interactions and magnetic fields on surface states of three-dimensional topological insulators (3D TIs). In this work we use an effective Hamiltonian to describe a slab of the 3D TI Bi$_2$Se$_3$. In the non-interacting limit, and for slab thicknesses...
