Origin of the fractional quantum Hall effect in wide quantum wells
Tongzhou Zhao, William N. Faugno, Songyang Pu +2
The nature of the fractional quantum Hall effect at observed in wide quantum wells almost three decades ago is still under debate. Previous studies have investigated it by…
Bloch Ferromagnetism of Composite Fermions
Md. Shafayat Hossain, Tongzhou Zhao, Songyang Pu +9
In 1929 Felix Bloch suggested that the paramagnetic Fermi sea of electrons should make a spontaneous transition to a fully-magnetized state at very low densities, because the excha…
Hall Viscosity of the Composite-Fermion Fermi Seas for Fermions and Bosons
Songyang Pu
The Hall viscosity has been proposed as a topological property of incompressible fractional quantum Hall states and can be evaluated as Berry curvature. This paper reports on the H…
Interplay between fractional quantum Hall liquid and crystal phases at low filling
Zheng-Wei Zuo, Ajit C. Balram, Songyang Pu +4
The nature of the state at low Landau-level filling factors has been a longstanding puzzle in the field of the fractional quantum Hall effect. While theoretical calculations sugges…
