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...
This thesis is dedicated to the study of quantum phase transitions in 2D Dirac semimetals. In Chapter 1, we first briefly review how Dirac fermions emerge in condensed matter systems and then briefly review the physics of quantum phase transitions. Chapter 2 is devoted to the field-theoretic...
This thesis provides a theoretical discussion of several new phenomena associated with spin-orbit coupling in systems that lack inversion symmetry. Chapter 1 gives an introduction to the context of spin-orbit coupling in condensed matter physics and the role of inversion symmetry breaking. The...
