Valley Isospin Controlled Fractional Quantum Hall States in Bilayer Graphene
Ke Huang, Hailong Fu, Danielle Reifsnyder Hickey +5
A two-dimensional electron system placed in a magnetic field develops Landau levels, where strong Coulomb interactions lead to the appearance of many-body correlated ground states.…
Low-Temperature Conductivity of Weakly Interacting Quantum Spin Hall Edges in Strained-Layer InAs/GaInSb
Tingxin Li, Pengjie Wang, Gerard Sullivan +2
We report low-temperature transport measurements in strained InAs/Ga0.68In0.32Sb quantum wells, which supports time-reversal symmetry-protected helical edge states. The temperature…
Nonlinear Transport of Graphene in the Quantum Hall Regime
Shibing Tian, Pengjie Wang, Xin Liu +6
We have studied the breakdown of the integer quantum Hall (QH) effect with fully broken symmetry, in an ultra-high mobility graphene device sandwiched between two single crystal he…
Observation of a Helical Luttinger-Liquid in InAs/GaSb Quantum Spin Hall Edges
Tingxin Li, Pengjie Wang, Hailong Fu +8
We report on the observation of a helical Luttinger-liquid in the edge of InAs/GaSb quantum spin Hall insulator, which shows characteristic suppression of conductance at low temper…
