Disorder effects on superconducting tendencies in the checkerboard Hubbard model
Peter M. Smith, Malcolm P. Kennett
The question of whether spatially inhomogeneous hopping in the two dimensional Hubbard model can lead to enhancement of superconductivity has been tackled by a number of authors in…
Decoherence induced deformation of the ground state in adiabatic quantum computation
Qiang Deng, Dmitri V. Averin, Mohammad H. Amin +1
Despite more than a decade of research on adiabatic quantum computation (AQC), its decoherence properties are still poorly understood. Many theoretical works have suggested that AQ…
Asymmetric spatial structure of zero modes for birefringent Dirac fermions
Bitan Roy, Peter M. Smith, Malcolm P. Kennett
We study the zero energy modes that arise in an unusual vortex configuration involving both the kinetic energy and an appropriate mass term in a model which exhibits birefringent D…
Adiabatic quantum optimization with qudits
M. H. S. Amin, Neil G. Dickson, Peter Smith
Most realistic solid state devices considered as qubits are not true two-state systems but multi-level systems. They can approximately be considered as qubits only if the energy se…
Birefringent break up of Dirac fermions in a square optical lattice
Malcolm P. Kennett, Nazanin Komeilizadeh, Kamran Kaveh +1
We generalize a proposal by Sorensen et al. [Phys. Rev. Lett. 94, 086803 (2005)] for creating an artificial magnetic field in a cold atom system on a square optical lattice. This l…
Tuning the effects of Landau-level mixing on anisotropic transport in quantum Hall systems
Peter M. Smith, Malcolm P. Kennett
Electron-electron interactions in half-filled high Landau levels in two-dimensional electron gases in a strong perpendicular magnetic field can lead to states with anisotropic long…
