Freezing of the quantum Hall liquid at nu =1/7 and 1/9.
We compare the free energy computed from the ground state energy and lowlying excitations of the 2-D Wigner solid and the fractional quantum Hall liquid, at magnetic filling factors ν = 1/7 and 1/9. We find that the Wigner solid melts into the fractional quantum Hall liquid at roughly the same temperature as that of some recent luminescence experiments, while it remains a solid at the lower tem...
متن کاملQuantum Hall Liquid Crystals
In this report we summarize a recent progress in exploration of correlated two-dimensional electron states in partially filled high Landau levels. At a mean-field Hartree-Fock level they can be described as charge-density waves, either unidirectional (stripes) or with the symmetry of the triangular lattice (bubbles). Thermal and quantum fluctuations have a profound effect on the stripe density ...
متن کاملElectrostatics of Inhomogeneous Quantum Hall Liquid
The distribution of electron density in the quantum Hall liquid is considered in the presence of macroscopic density gradient caused by side electrodes or inhomogeneous doping. In this case different Landau levels are occupied in different regions of a sample. These regions are separated by “incompressible liquid”. It is shown that the applicability of the approach by Chklovskii et al. is subst...
متن کاملHelical liquid and the edge of quantum spin Hall systems.
The edge states of the recently proposed quantum spin Hall systems constitute a new symmetry class of one-dimensional liquids dubbed the "helical liquid," where the spin orientation is determined by the direction of electron motion. We prove a no-go theorem which states that a helical liquid with an odd number of components cannot be constructed in a purely 1D lattice system. In a helical liqui...
متن کاملLiquid crystalline states in quantum Hall systems
We investigate liquid crystalline phases with nematic order at 3 -filling of the valence Landau level (LL). We generalize Laughlin’s fractional quantum Hall (QH) effect wavefunction at ν = 3 to include anisotropic nodal distribution by modifying the Jastrow factors. Lengthy Monte Carlo simulations are then used to determine with unprecedented accuracy the (anisotropic) pair distribution functio...
