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…
Berry phase in superconducting multiterminal quantum dots
Benoit Doucot, Romain Danneau, Kang Yang +2
We report on the study of the non-trivial Berry phase in superconducting multiterminal quantum dots biased at commensurate voltages. Starting with the time-periodic Bogoliubov-de G…
Engineering the Floquet spectrum of superconducting multiterminal quantum dots
Régis Mélin, Romain Danneau, Kang Yang +2
Here we present a theoretical investigation of the Floquet spectrum in multiterminal quantum dot Josephson junctions biased with commensurate voltages. We first draw an analogy bet…
Competing Fractional Quantum Hall and Electron Solid Phases in Graphene
Shaowen Chen, Rebeca Ribeiro-Palau, Kang Yang +5
We report experimental observation of the reentrant integer quantum Hall effect in graphene, appearing in the N2 Landau level. Similar to high-mobility GaAs/AlGaAs heterostructu…
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…
