Light-induced fractional quantum Hall phases in graphene
Areg Ghazaryan, Tobias Graß, Michael J. Gullans +2
We show how to realize two-component fractional quantum Hall phases in monolayer graphene by optically driving the system. A laser is tuned into resonance between two Landau levels…
Positive Quantum Magnetoresistance in Tilted Magnetic Field
William Mayer, Areg Ghazaryan, Pouyan Ghaemi +2
Transport properties of highly mobile 2D electrons are studied in symmetric GaAs quantum wells placed in titled magnetic fields. Quantum positive magnetoresistance (QPMR) is observ…
Competing Adiabatic Thouless Pumps in Enlarged Parameter Spaces
Pedro L. S. Lopes, Pouyan Ghaemi, Shinsei Ryu +1
The transfer of conserved charges through insulating matter via smooth deformations of the Hamiltonian is known as quantum adiabatic, or Thouless, pumping. Central to this phenomen…
