Bulk Dirac points in distorted spinels
Julia A. Steinberg, Steve M. Young, Saad Zaheer +3
We report on a Dirac-like Fermi surface in three-dimensional bulk materials in a distorted spinel structure on the basis of density functional theory (DFT) as well as tight-binding…
Spin texture on the Fermi surface of tensile strained HgTe
Saad Zaheer, S. M. Young, D. Cellucci +4
We present ab initio and k.p calculations of the spin texture on the Fermi surface of tensile strained HgTe, which is obtained by stretching the zincblende lattice along the (111)…
Dirac semimetal in three dimensions
S. M. Young, S. Zaheer, J. C. Y. Teo +3
In a Dirac semimetal, the conduction and valence bands contact only at discrete (Dirac) points in the Brillouin zone (BZ) and disperse linearly in all directions around these criti…
Casimir potential of a compact object enclosed by a spherical cavity
Saad Zaheer, Sahand Jamal Rahi, Thorsten Emig +1
We study the electromagnetic Casimir interaction of a compact object contained inside a closed cavity of another compact object. We express the interaction energy in terms of the o…
Casimir spring and compass: Stable levitation and alignment of compact objects
Sahand Jamal Rahi, Saad Zaheer
We investigate a stable Casimir force configuration consisting of an object contained inside a spherical or spheroidal cavity filled with a dielectric medium. The spring constant f…
Casimir interactions of an object inside a spherical metal shell
Saad Zaheer, Sahand Jamal Rahi, Thorsten Emig +1
We investigate the electromagnetic Casimir interactions of an object contained within an otherwise empty, perfectly conducting spherical shell. For a small object we present analyt…
