Fractional quantum Hall effect of hard-core bosons in topological flat bands.
Recent proposals of topological flat band models have provided a new route to realize the fractional quantum Hall effect without Landau levels. We study hard-core bosons with short-range interactions in two representative topological flat band models, one of which is the well-known Haldane model (but with different parameters). We demonstrate that fractional quantum Hall states emerge with sign...
متن کاملTopological flat bands from dipolar spin systems.
We propose and analyze a physical system that naturally admits two-dimensional topological nearly flat bands. Our approach utilizes an array of three-level dipoles (effective S=1 spins) driven by inhomogeneous electromagnetic fields. The dipolar interactions produce arbitrary uniform background gauge fields for an effective collection of conserved hard-core bosons, namely, the dressed spin flip...
متن کاملTopological quantum numbers in the Hall effect
Topological quantum numbers account for the precise quantization that occurs in the integer Hall effect. In this theory, Kubo’s formula for the conductance acquires a topological interpretation in terms of Chern numbers and their non-commutative analog, the Fredholm Indices.

متن کاملQuantum Hall Effects
1 Preface The present notes cover a series of three lectures on the quantum Hall effect given at the Singapore session " Ultracold Gases and Quantum Information " at Les Houches Summer School 2009. Almost 30 years after the discovery of the quantum Hall effect, the research subject of quantum Hall physics has certainly acquired a certain degree of maturity that is reflected by a certain number ...
