Occupation numbers in a quantum canonical ensemble: a projection operator approach
Wim Magnus, Fons Brosens
Recently, we have used a projection operator to fix the number of particles in a second quantization approach in order to deal with the canonical ensemble. Having been applied earl…
Theoretical study of scattering in graphene ribbons in the presence of structural and atomistic edge roughness
Kristof Moors, Antonino Contino, Maarten L. Van de Put +4
We investigate the diffusive electron-transport properties of charge-doped graphene ribbons and nanoribbons with imperfect edges. We consider different regimes of edge scattering,…
Anisotropic bulk and planar Heisenberg ferromagnets in uniform, arbitrarily oriented magnetic fields
Joren Vanherck, Bart Sorée, Wim Magnus
Today, further downscaling of mobile electronic devices poses serious problems, such as energy consumption and local heat dissipation. In this context, spin wave majority gates mad…
Efficient solution of the Wigner-Liouville equation using a spectral decomposition of the force field
Maarten L. Van de Put, Bart Sorée, Wim Magnus
The Wigner-Liouville equation is reformulated using a spectral decomposition of the classical force field instead of the potential energy. The latter is shown to simplify the Wigne…
An envelope function formalism for lattice-matched heterostructures
Maarten L. Van de Put, William G. Vandenberghe, Wim Magnus +1
The envelope function method traditionally employs a single basis set which, in practice, relates to a single material because the matrix elements are generally only kno…
