Fractional quantum Hall effect at the filling factor
Ken K. W. Ma, Michael R. Peterson, V. W. Scarola +1
The fractional quantum Hall (FQH) effect at the filling factor was discovered in GaAs heterostructures more than 35 years ago. Various topological orders have been proposed…
Majorana corner modes with solitons in an attractive Hubbard-Hofstadter model of cold atom optical lattices
Chuanchang Zeng, T. D. Stanescu, Chuanwei Zhang +2
Higher order topological superconductors hosting Majorana-Kramers pairs (MKPs) as corner modes have recently been proposed in a two-dimensional (2D) quantum spin Hall insulator (QS…
Robustness of topologically protected surface states in layering of Bi2Te3 thin films
Kyungwha Park, J. J. Heremans, V. W. Scarola +1
Bulk Bi2Te3 is known to be a topological insulator. We investigate surface states of Bi2Te3(111) thin films using density-functional theory including spin-orbit coupling. We constr…
Subband Engineering Even-Denominator Quantum Hall States
V. W. Scarola, C. May, M. R. Peterson +1
Proposed even-denominator fractional quantum Hall effect (FQHE) states suggest the possibility of excitations with non-Abelian braid statistics. Recent experiments on wide square q…
Pseudospin and Quantum Computation in Semiconductor Nanostructures
V. W. Scarola, K. Park, S. Das Sarma
We review the theoretical aspects of pseudospin quantum computation using vertically coupled quantum dots in the quantum Hall regime. We discuss the robustness and addressability o…
The Exchange Gate in Solid State Spin Quantum Computation: The Applicability of the Heisenberg Model
V. W. Scarola, S. Das Sarma
Solid state quantum computing proposals rely on adiabatic operations of the exchange gate among localized spins in nanostructures. We study corrections to the Heisenberg interactio…
