Electronic structure of interfaces between hexagonal and rhombohedral graphite
M. Taut, K. Koepernik
The electronic structure including energy bands, band weights, and local density of states (LDOS) of interfaces between hexagonal (AB) and rhombohedral (ABC) graphite has been has…
Electronic structure of stacking faults in hexagonal graphite
M. Taut, K. Koepernik, M. Richter
We present results of self-consistent, full-potential electronic structure calculations for slabs of hexagonal graphite with stacking faults and for slabs with one displaced surfac…
Density-functional investigation of rhombohedral stacks of graphene: topological surface states, nonlinear dielectric response, and bulk limit
Ruijuan Xiao, F. Tasnádi, K. Koepernik +3
A DFT-based investigation of rhombohedral (ABC)-type graphene stacks in finite static electric fields is presented. Electronic band structures and field-induced charge densities ar…
Exact solutions for a two-electron quantum dot model in a magnetic field and application to more complex systems
Manfred Taut, Helmut Eschrig
We discussed exact solutions of the Schroedinger equation for a two-dimensional parabolic confinement potential in a homogeneous external magnetic field. It turns out that the two-…
Distortion of Wigner molecules : pair function approach
M. Taut
We considered a two dimensional three electron quantum dot in a magnetic field in the Wigner limit. A unitary coordinate transformation decouples the Hamiltonian (with Coulomb inte…
Broken Generalized Kohn Theorem in Harmonic Dot Lattices due to Coulomb Interaction between the Dots: Exact solution of the Schrödinger equation in the dipole approximation
M. Taut
The Generalized Kohn Theorem in arrays of parabolic quantum dots with Coulomb interaction between the dots is violated, if there are different dot species involved. We solve the Sc…
