A different view of the quantum Hall plateau-to-plateau transitions
D. Shahar, D. C. Tsui, M. Shayegan +2
We demonstrate experimentally that the transitions between adjacent integer quantum Hall (QH) states are equivalent to a QH-to-insulator transition occurring in the top Landau leve…
Duality Near Quantum Hall Transitions
E. Shimshoni, S. L. Sondhi, D. Shahar
A recent experiment by Shahar et al, on the phase transitions between quantum Hall states and the insulator, found that the current-voltage characteristics in the two phases are re…
Continuous Quantum Phase Transitions
S. L. Sondhi, S. M. Girvin, J. P. Carini +1
A quantum system can undergo a continuous phase transition at the absolute zero of temperature as some parameter entering its Hamiltonian is varied. These transitions are particula…
The Nature of the Hall Insulator
D. Shahar, D. C. Tsui, M. Shayegan +3
We have conducted an experimental study of the linear transport properties of the magnetic-field induced insulating phase which terminates the quantum Hall (QH) series in two dimen…
