Quantum Hall effect in a singly and doubly connected three-dimensional topological insulator
Quantum Hall effect in a singly and doubly connected three-dimensional topological insulator
The surface states of topological insulators, which behave as charged massless Dirac fermions, are studied in the presence of a quantizing uniform magnetic field. Using the method of Lee, [Phys. Rev. Lett. 103, 196804 (2009)], the analytical formula satisfied by the energy spectrum is found for a singly and doubly …
