Theory of unconventional quantum Hall effect in strained graphene
Bitan Roy, Zi-Xiang Hu, Kun Yang
We show through both theoretical arguments and numerical calculations that graphene discerns an unconventional sequence of quantized Hall conductivity, when subject to both magneti…
Comparison of the density-matrix renormalization group method applied to fractional quantum Hall systems in different geometries
Zi-Xiang Hu, Z. Papic, S. Johri +2
We report a systematic study of the fractional quantum Hall effect (FQHE) using the density-matrix renormalization group (DMRG) method on two different geometries: the sphere and t…
Bulk and edge quasihole tunneling amplitudes in the Laughlin state
Zi-xiang Hu, Ki Hoon Lee, Xin wan
The tunneling between the Laughlin state and its quasihole excitations are studied by using the Jack polynomial. We find a universal analytical formula for the tunneling amplitude,…
Model Wavefunctions for the Collective Modes and the Magneto-roton Theory of the Fractional Quantum Hall Effect
Bo Yang, Zi-Xiang Hu, Z. Papic +1
We construct model wavefunctions for the collective modes of fractional quantum Hall systems. The wavefunctions are expressed in terms of symmetric polynomials characterized by a r…
