Query: AdS/QHE: Towards a Holographic Description of Quantum Hall Experiments   Transitions among quantum Hall plateaux share a suite of remarkable
experimental features, such as semi-circle laws and duality relations, whose
accuracy and robustness are difficult to explain directly in terms of the
detailed dynamics of the microscopic electrons. They would naturally follow if
the low-energy transport properties were governed by an emergent discrete
duality group relating the different plateaux, but no explicit examples of
interacting systems having such a group are known. Recent progress using the
AdS/CFT correspondence has identified examples with similar duality groups, but
without the DC ohmic conductivity characteristic of quantum Hall experiments.
We use this to propose a simple holographic model for low-energy quantum Hall
systems, with a nonzero DC conductivity that automatically exhibits all of the
observed consequences of duality, including the existence of the plateaux and
the semi-circle transitions between them. The model can be regarded as a
strongly coupled analog of the old `composite boson' picture of quantum Hall
systems. Non-universal features of the model can be used to test whether it
describes actual materials, and we comment on some of these in our proposed
model.
