We study the separability of the state space of loop quantum gravity. In the standard construction, the kinematical Hilbert space of the diffeomorphism-invariant states is nonseparable. This is aâ€¦ (More)

We study how physical information can be extracted from a background independent quantum system. We use an extremely simple â€˜minimalistâ€™ system that models a finite region of 3d euclidean quantumâ€¦ (More)

Recently LIPKIN (1) has suggested that strongly interacting particles might be combined into ,hyper-supormult iplets ~) by utilizing the (~ barbaryon )) classification. Such multiplets were obtainedâ€¦ (More)

We study the separability of the state space of loop quantum gravity. In the standard construction, the kinematical Hilbert space of the diffeomorphism-invariant states is nonseparable. This is aâ€¦ (More)

THE ionization potentials of the members of the n-paraffin series of hydrocarbons have been calculated on the assumption that the electron which is removed comes from a symmetrical molecularâ€¦ (More)

For a helical magnet the axis of the helix is a hard axis in most materials but the moments are never constrained so completely. Without that restriction the moments have two degrees of freedom. Theâ€¦ (More)

We study the coupling of massive fermions to the quantum mechanical dynamics of spacetime emerging from the spinfoam approach in three dimensions. We first recall the classical theory beforeâ€¦ (More)
