Integer quantum Hall transition in a of a Landau level
Matteo Ippoliti, Scott D. Geraedts, R. N. Bhatt
We investigate the quantum Hall problem in the lowest Landau level in two dimensions, in the presence of an arbitrary number of -function potentials arranged in different geomet…
Composite fermions in bands with N-fold rotational symmetry
Matteo Ippoliti, Scott D. Geraedts, R. N. Bhatt
We study the effect of band anisotropy with discrete rotational symmetry (where ) in the quantum Hall regime of two-dimensional electron systems. We focus on the comp…
Connection between Fermi contours of zero-field electrons and composite fermions in two-dimensional systems
Matteo Ippoliti, Scott D. Geraedts, R. N. Bhatt
We investigate the relation between the Fermi sea (FS) of zero-field carriers in two-dimensional systems and the FS of the corresponding composite fermions which emerge in a high m…
Numerical study of anisotropy in a composite Fermi liquid
Matteo Ippoliti, Scott D. Geraedts, R. N. Bhatt
We perform density-matrix renormalization group studies of a two-dimensional electron gas in a high magnetic field and with an anisotropic band mass. At half-filling in the lowest…
