Interaction-driven capacitance in Graphene electron-hole double layer in the quantum Hall regime
Bahman Roostaei
Fabrication of devices made by isolated Graphene or Graphene-like single layers (such as h-BN) has opened up possibility of examining highly correlated states of electron systems i…
Current Induced Vortex Wall Dynamics in Helical Magnetic Systems
Bahman Roostaei
Nontrivial topology of interfaces separating anti-chiral phases in helical magnets result in new effects as they interact with spin polarized current. These interfces or vortex wal…
Vortex Wall Dynamics and Pinning in Helical Magnets
Bahman Roostaei
Domain walls formed by one dimensional array of vortex lines have been recently predicted to exist in disordered helical magnets and multiferroics. These systems are on one hand an…
Pinning theory of domain walls in helical magnets
Bahman Roostaei, Thomas Nattermann
The theory of elasticity and pinning of domain walls in helical magnets is presented. Domain walls perpendicular to the helical axis show non-local elasticity and are marginally pi…
Dynamical Magnetic and Nuclear Polarization in Complex Spin Systems: Semi-magnetic II-VI Quantum Dots
Ramin M. Abolfath, Anna Trojnar, Bahman Roostaei +2
Dynamical magnetic and nuclear polarization in complex spin systems is discussed on the example of transfer of spin from exciton to the central spin of magnetic impurity in a quant…
Theory of Activated Transport in Bilayer Quantum Hall Systems
Bahman Roostaei, Kieran J. Mullen, Herbert A. Fertig +1
We analyze the transport properties of bilayer quantum Hall systems at total filling factor in drag geometries as a function of interlayer bias, in the limit where the disord…
