How quantum is quantum geometry?
Ady Stern, Felix von Oppen
The quantum geometric tensor - the Berry curvature together with the quantum metric - now underlies a long list of observables, from the anomalous Hall effect to the superfluid wei…
Coupled-layer description of topological crystalline insulators
I. C. Fulga, N. Avraham, H. Beidenkopf +1
We introduce a coupled-layer construction to describe three-dimensional topological crystalline insulators protected by reflection symmetry. Our approach uses stacks of weakly-coup…
Oscillating sign of drag in high Landau levels
Felix von Oppen, Steven H. Simon, Ady Stern
Motivated by experiments, we study the sign of the Coulomb drag voltage in a double layer system in a strong magnetic field. We show that the commonly used Fermi Golden Rule approa…
Mesoscopic fluctuations of the Coulomb drag at =1/2
B. N. Narozhny, I. L. Aleiner, Ady Stern
We consider mesoscopic fluctuations of Coulomb drag transresistivity between two layers at a Landau level filling factor each. We find that at low temperature sample to sam…
Conductivity tensor of striped quantum Hall phases
Felix von Oppen, Bertrand I. Halperin, Ady Stern
We study the transport properties of pinned striped quantum Hall phases. We show that under quite general assumptions, the macroscopic conductivity tensor satisfies a semicircle la…
On the Relation between Interband Scattering and the "Metallic Phase" of Two Dimensional Holes in GaAs/AlGaAs
Yuval Yaish, Oleg Prus, Evgeny Buchstab +4
The "metallic" regime of holes in GaAs/AlGaAs heterostructures corresponds to densities where two splitted heavy hole bands exist at a zero magnetic field. Using Landau fan diagram…
