Doped moiré magnets: renormalized flat bands and excitonic phases
Ilia Komissarov, Onur Erten, Pouyan Ghaemi
We explore the phase diagram of a twisted bilayer of strongly interacting electrons on a honeycomb lattice close to half-filling using the slave boson mean-field theory. Our analys…
Anomalous Shiba states in topological iron-based superconductors
Areg Ghazaryan, Ammar Kirmani, Rafael M. Fernandes +1
We demonstrate the formation of robust zero energy modes close to magnetic impurities in the iron-based superconductor FeSeTe. We find that the Zeeman field generated b…
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…
Non-Abelian SU(2) gauge fields through density-wave order and strain in graphene
Sarang Gopalakrishnan, Pouyan Ghaemi, Shinsei Ryu
Spatially varying strain patterns can qualitatively alter the electronic properties of graphene, acting as effective valley-dependent magnetic fields and giving rise to pseudo-Land…
