A ug 2 00 2 Spin polarised particles in Gödel world
نویسنده
چکیده
The motion of classical test spinning particles in Gödel universe in the realm of Einstein’s General Relativity (GR) is investigated by making use of Killing conserved currents. We consider three distinct cases of motion of spinning particles polarized along the three distinct axes of the anisotropic metric. It is shown that in the case the spin is polarised along the y − direction the minimum energy of the motion is attained for only for spinless particles while the other two directions the minimum energy is obtained for spinning particles. The continuos energy spectrum is also computed. Departamento de F́ısica Teórica Instituto de F́ısica UERJ Rua São Fco.

We find a quantum mechanical formulation of proper time for spin 1/2 particles within the framework of the Dirac theory. It is shown that the rate of proper time can be represented by an operator called the “tempo operator”, and that the proper time itself be given by the integral of the expectation value of the operator. The tempo operator has some terms involving the Pauli spin matrices, and ...

Two consecutive measurements of the position of a non relativistic free particle will give entirely unrelated results. Recent quantum information research by G. Svetlichny, J. Tolar, and G. Chadzitaskos have explained this property of position observables as a result of a path in the Feynman integral being mathematically defined as a product of incompatible states; that is, as a product of mutu...

of 3d transition metals (Sc, Ti, Cr, Mn , Fe, Co, Ni) in both far and close situations were studied based on spin polarised density functional theory using the generalized gradient approximation (LDA) with SIESTA code. The electronic structures show that zigzag (0,9) GaAs nanotubes are non-magnetic semiconductors with direct band gap. It was revealed that doping of 11.11 % Fe and Mn concentrati...

We show that a particle, with positive orbital angular momentum, following an outgoing null/time-like geodesic, shall never reach the closed time like horizon (CTH) present in the (4+1)dimensional rotating Gödel black hole space-time. Therefore a large part of this space-time remains inaccessible to a large class of geodesic observers, depending on the conserved quantities associated with them....

We describe gapped single-particle and collective excitations across a superfluid to insulator quantum phase transition of particles (bosons or fermions) in a periodic potential, with an even number of particles per unit cell. We demonstrate that the dynamics is controlled by a quantum impurity problem of a localized particle interacting with the bulk critical modes. Critical exponents are dete...
