The fundamental collective degree of freedom of fractional quantum Hall states is identified as a unimodular two-dimensional spatial metric that characterizes the local shape of the correlations of the incompressible fluid. Its quantum fluctuations are controlled by a topologically quantized "guiding-center spin." Charge fluctuations are proportional to its Gaussian curvature. 

Microscopic diagnosis of universal geometric responses in fractional quantum Hall liquids

Topological quantum liquids contain internal degrees of freedom that are coupled to geometric response. Here, the authors present a method, with the help of the Dehn twist on the torus geometry, to

Quantum Geometry and Topology

Attempts to understand the phenomenon of the robustness of the values of the Hall conductivity in quantum Hall systems led to the idea of characterizing the ground state of many electron systems

Chiral Gravitons in Fractional Quantum Hall Liquids.

It is demonstrated that they are chiral gravitons carrying angular momentum -2, which are quanta of quantum motion of an internal metric, and show up as resonance peaks in the system's response to what is the fractional Hall analog of gravitational waves.

Quantum Hall physics : Hierarchies and conformal field theory techniques

The fractional quantum Hall effect, being one of the most studied phenomena in condensed matter physics during the past 30 years, has generated many ground-breaking new ideas and concepts. Very ear

Hall viscosity of hierarchical quantum Hall states

Using methods based on conformal field theory, we construct model wave functions on a torus with arbitrary flat metric for all chiral states in the abelian quantum Hall hierarchy. These functions h

Single-mode approximation for quantum Hall states with broken rotational symmetry

A topological phase can often be represented by a corresponding wavefunction (exact eigenstate of a model Hamiltonian) that has a higher underlying symmetry than necessary. When the symmetry is

Algebraic approach to fractional quantum Hall effect

We construct an algebraic description for the ground state and for the static response of the quantum Hall plateaux with filling factor $\nu=N/(2N+1)$ in the large $N$ limit. By analyzing the algebra

Fractional quantum Hall effect in semiconductor systems

The fractional quantum Hall (FQH) effect refers to the strongly-correlated phenomena and the as- sociated quantum phases of matter realized in a two-dimensional gas of electrons placed in a large

Non relativistic diffeomorphism and the geometry of the fractional quantum Hall effect

We show that our recently proposed method\cite{BMM1,BMM2,BMM3,BM4} of constructing nonrelativistic diffeomorphism invariant field theories by gauging the Galilean symmetry provides a natural
