Numerical solution of the radial Dirac equation in pseudopotential construction
Ondrej Certik
In the present work we study numerical solution of the radial Dirac equation in a specific case - ab-initio pseudopotential generating process - which is needed within the electron…
Simple derivation of the special theory of relativity without the speed of light axiom
Ondrej Certik
We show a very simple yet rigorous derivation of the invariance of the space-time interval (and hence the whole special relativity) just from the isotropy, homogeneity and a princi…
Integral and fractional Quantum Hall Ising ferromagnets
K. Vyborny, O. Certik, D. Pfannkuche +3
We compare quantum Hall systems at filling factor 2 to those at filling factors 2/3 and 2/5, corresponding to the exact filling of two lowest electron or composite fermion (CF) Lan…
Transport gap in a nu=1/3 quantum Hall system: a probe for skyrmions
A. F. Dethlefsen, R. J. Haug, K. Vyborny +2
The dependence of the activated gap on magnetic field is studied for the fractional filling factor~1/3. By comparing the experimental results with results from exact diagonalizatio…
