Anomalous fractional quantum Hall effect and multi-valued Hamiltonians
Xi Wu, M. A. Zubkov
We discuss anomalous fractional quantum Hall effect that exists without external magnetic field. We propose that excitations in such systems may be described effectively by non-int…

TKNN formula for general lattice Hamiltonian in odd dimensions
Hidenori Fukaya, Tetsuya Onogi, Satoshi Yamaguchi +1
Topological insulators in odd dimensions are characterized by topological numbers. We prove the well-known relation between the topological number given by the Chern character of t…

Quantum Hall conductivity in the presence of interactions
Xi Wu, M. A. Zubkov
We discuss quantum Hall effect in the presence of arbitrary pair interactions between electrons. It is shown that irrespective of the interaction strength the Hall conductivity is…
