Universal Periods in Quantum Hall Droplets [PDF]

, 2007
Using the hierarchy picture of the fractional quantum Hall effect, we study the ground-state periodicity of a finite size quantum Hall droplet in a quantum Hall fluid of a different filling factor.

Roadmap for quantum simulation of the fractional quantum Hall effect [PDF]

Physical Review A, 2020
A major motivation for building a quantum computer is that it provides a tool to efficiently simulate strongly correlated quantum systems. In this work, we present a detailed roadmap on how to simulate a two-dimensional electron gas---cooled to absolute zero and pierced by a strong transversal magnetic field---on a quantum computer.

From Fractional Chern Insulators to a Fractional Quantum Spin Hall Effect

, 2012
We investigate the algebraic structure of flat energy bands a partial filling of which may give rise to a fractional quantum anomalous Hall effect (or a fractional Chern insulator) and a fractional quantum spin Hall effect. Both effects arise in the case

Microscopic theory for nematic fractional quantum Hall effect

Physical Review Research, 2020
We analyze various microscopic properties of the nematic fractional quantum Hall effect (FQHN) in the thermodynamic limit, and present necessary conditions required of the microscopic Hamiltonians for the nematic fractional quantum Hall effect to be ...

Exclusonic Quasiparticles and Thermodynamics of Fractional Quantum Hall Liquids

, 1997
Quasielectrons and quasiholes in the fractional quantum Hall liquids obey fractional (including nontrivial mutual) exclusion statistics. Their statistics matrix can be determined from several possible state-counting scheme, involving different ...

Haldane fractional statistics in the fractional quantum Hall effect [PDF]

Physical Review B, 1994
We have tested Haldane's ``fractional-Pauli-principle'' description of excitations around the $ = 1/3$ state in the FQHE, using exact results for small systems of electrons. We find that Haldane's prediction $ = \pm 1/m$ for quasiholes and quasiparticles, respectively, describes our results well with the modification $ _{qp} = 2-1/3$ rather than $-1/

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Towards the fractional quantum Hall effect: a noncommutative geometry perspective [PDF]

, 2005
In this paper we give a survey of some models of the integer and fractional quantum Hall effect based on noncommutative geometry. We begin by recalling some classical geometry of electrons in solids and the passage to noncommutative geometry produced by ...

Experimental investigation of the edge states structure at fractional filling factors

, 2005
We experimentally study electron transport between edge states in the fractional quantum Hall effect regime. We find an anomalous increase of the transport across the 2/3 incompressible fractional stripe in comparison with theoretical predictions for the
