Geometric measure of entanglement for pure states and mean value of spin
Andrzej M. Frydryszak, Volodymyr M. Tkachuk
We derive an explicit expression for geometric measure of entanglement for spin and other quantum system. A relation of entanglement in pure state with the mean value of spin is gi…

Quantum brachistochrone problem for two spins-1/2 with anisotropic Heisenberg interaction
A. R. Kuzmak, V. M. Tkachuk
We study the quantum brachistochrone evolution for a system of two spins- described by an anisotropic Heisenberg Hamiltonian without , interacting couplings i…

Deformed Heisenberg algebra and minimal length
T. Masłowski, A. Nowicki, V. M. Tkachuk
A one-dimensional deformed Heisenberg algebra is studied. We answer the question: For what function of deformation there exists a nonzero minimal uncertainty i…
