A four-dimensional generalization of the quantum Hall effect.

چکیده
We construct a generalization of the quantum Hall effect, where particles move in four dimensional space under a SU(2) gauge field. This system has a macroscopic number of degenerate single particle states. At appropriate integer or fractional filling fractions the system forms an incompressible quantum liquid. Gapped elementary excitation in the bulk interior and gapless elementary excitations at the boundary are investigated.

Geometric Construction of the Quantum Hall Effect in Higher Dimensions
A clean geometric construction is presented for the recent generalization of the Quantum Hall Effect to higher dimensional spaces. A very explicit formula is derived for the Hamiltonian in the generalized Quantum Hall Effect. This explicit formula suggests that the quantum Hall effect in even dimensions larger than two turns out to be simply copies of the two-dimensional effect.

In this paper we study the integer quantum Hall effect (IQHE) on the systems with different types of impurities in delta and gaussian forms. The Landau energy levels in the presence of impurity split in two different levels,the extended and localized levels, emerging then the Hall step. Finally, we add a specified form of a quantum dot potential to a system with impurity, and observed that incr...
متن کاملEffective Field Theory Description of the Higher DimensionalQuantum Hall Liquid
We derive an effective topological field theory model of the four dimensional quantum Hall liquid state recently constructed by Zhang and Hu. Using a generalization of the flux attachment transformation, the effective field theory can be formulated as a U (1) Chern–Simons theory over the total configuration space C P3, or as a SU (2) Chern–Simons theory over S4. The new quantum Hall liquid supp...
متن کاملThe global phase diagram of a modular invariant two dimensional statistical model
A generalization of the Coulomb Gas model with modular SL(2, Z)symmetry allows for a discrete infinity of phases which are characterized by the condensation of dyonic pseudoparticles and the breaking of parity and time reversal. Here we study the phase diagram of such a model by using renormalization group techniques. Then the symmetry SL(2, Z) acting on the two-dimensional parameter space give...
متن کاملشبیه سازی اثر بی نظمی و میدان مغناطیسی بر ترابرد کوانتومی نانوساختارهای دو بعدی مدل شده با تقریب تنگابست
In recent years, semiconductor nanostructures have become the model systems of choice for investigation of electrical conduction on short length scales. Quantum transport is studied in a two dimensional electron gas because of the combination of a large Fermi wavelength and large mean free path. In the present work, a numerical method is implemented in order to contribute to the understanding ...
