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…
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…
Hamiltonian theory for Quantum Hall systems in a tilted magnetic field: robustness of activation gaps
Kang Yang, Mark Oliver Goerbig, Benoît Douçot
We use the Hamiltonian theory developed by Shankar and Murthy to study a quantum Hall system in a tilted magnetic field. With a finite width of the system in the direction, the…
Spin-valley skyrmions in graphene at filling factor
Yunlong Lian, Mark O. Goerbig
We model quantum Hall skyrmions in graphene monolayer at quarter filling by a theory of CP3 fields and study the energy minimizing skyrmions in presence of valley pseudospin anisot…
Flat-band ferromagnetism in a topological Hubbard model
R. L. Doretto, M. O. Goerbig
We study the flat-band ferromagnetic phase of a topological Hubbard model within a bosonization formalism and, in particular, determine the spin-wave excitation spectrum. We consid…
Bandwidth-resonant Floquet states in honeycomb optical lattices
Anton Quelle, Mark Goerbig, Cristiane Morais Smith
We investigate, within Floquet theory, topological phases in the out-of-equilibrium system that consists of fermions in a circularly shaken honeycomb optical lattice. We concentrat…
