Particle-Hole Duality in the Lowest Landau Level
Dung Xuan Nguyen, Tankut Can, Andrey Gromov
We derive a number of exact relations between response functions of holomorphic, chiral fractional quantum Hall states and their particle-hole (PH) conjugates. These exact relation…
Exact Electromagnetic Response of Landau Level Electrons
Dung Xuan Nguyen, Andrey Gromov
We present a simple method that allows to calculate the electromagnetic response of non-interacting electrons in strong magnetic field to arbitrary order in the gradients of extern…
Higher-Spin Theory of the Magnetorotons
Siavash Golkar, Dung Xuan Nguyen, Matthew M. Roberts +1
Fractional quantum Hall liquids exhibit a rich set of excitations, the lowest-energy of which are the magnetorotons with dispersion minima at a finite momentum. We propose a theory…
