چکیده

The frictional drag between parallel two-dimensional electron systems has been measured in a regime of strong interlayer correlations. When the bilayer system enters the excitonic quantized Hall state at total Landau level filling factor nu(T) = 1, the longitudinal component of the drag vanishes but a strong Hall component develops. The Hall drag resistance is observed to be accurately quantized at h/e(2).

Bilayer quantum hall systems at nu(T)=1: coulomb drag and the transition from weak to strong interlayer coupling.

Measurements revealing anomalously large frictional drag at the transition between the weakly and strongly coupled regimes of a bilayer two-dimensional electron system at total Landau level filling factor nu(T)=1 are reported. This result suggests the existence of fluctuations, either static or dynamic, near the phase boundary separating the quantized Hall state at small layer separations from ...

Excitonic superfluid phase in Double Bilayer Graphene

Spatially indirect excitons can be created when an electron and a hole, confined to separate layers of a double quantum well system, bind to form a composite Boson[1, 2]. Because there is no recombination pathway such excitons are long lived making them accessible to transport studies. Moreover, the ability to independently tune both the intralayer charge density and interlayer electron-hole se...

اثرات بس ذره‌ای در مایعات الکترونی ابعاد کم

 This review article is about the role of electron-electron interactions in low dimensional systems and its transport properties in nano-structures. It begins with a review of the pair-distribution function theory of electron liquid systems taking into account the electron-electron interactions. We extend the theory for highly correlated system such two- and one-dimensional electron liquids. We...

Phase Diagram for Quantum Hall Bilayers at 1

116802-1 We present a phase diagram for a double quantum well bilayer electron gas in the quantum Hall regime at a total filling factor 1, based on exact numerical calculations of the topological Chern number matrix and the (interlayer) superfluid density. We find three phases: a quantized Hall state with pseudospin superfluidity, a quantized Hall state with pseudospin ‘‘gauge-glass’’ order, an...

Charge imbalance and bilayer two-dimensional electron systems at T=1

We use interlayer tunneling to study bilayer two-dimensional electron systems at T=1 over a wide range of charge-density imbalance = 1− 2 between the two layers. We find that the strongly enhanced tunneling associated with the coherent excitonic T=1 phase at small layer separation can survive at least up to an imbalance of =0.5, i.e., 1 , 2 = 3 /4,1 /4 . Phase transitions between the excitonic ...
