Charge density waves and their transitions in anisotropic quantum Hall systems
Yuchi He, Kang Yang, Mark Oliver Goerbig +1
In recent experiments, external anisotropy has been a useful tool to tune different phases and study their competitions. In this paper, we look at the quantum Hall charge density w…
Exceptional Spin Liquids from Couplings to the Environment
Kang Yang, Siddhardh C. Morampudi, Emil J. Bergholtz
We establish the appearance of a qualitatively new type of spin liquid with emergent exceptional points when coupling to the environment. We consider an open system of the Kitaev h…
Collective excitations of quantum Hall states under tilted magnetic field
Kang Yang, Mark Goerbig, Benoît Douçot
We study the neutral excitations of fractional quantum Hall states in electronic systems of finite width where an external anisotropy is introduced by tilting the magnetic field. A…
