Pauli effects in uncertainty relations
I.V. Toranzo a c, P. Sánchez-Moreno b c, R.O. Esquivel c d, J.S. Dehesa a c In this Letter we analyze the effect of the spin dimensionality of a physical system in two mathematical formulations of the uncertainty principle: a generalized Heisenberg uncertainty relation valid for all antisymmetric N-fermion wavefunctions, and the Fisher-information-based uncertainty relation…

A Density Functional study of Covalency in the Trihalides of Lutetium and Lawrencium
Ossama Kullie In this work we present a four component relativistic theoretical investigation of the trihalides of lutetium and lawrencium, LuX3, LrX3 (X= F, Cl, Br, I) respectively using density functional theory (DFT) with different density functional and a geometrical optimisation procedure as implemented in DIRAC-package. The results show the trend of bonding from lighter…
