Reply to `Comment on "Quantum Bounce and Cosmic Recall"' [arXiv:0811.2790]
Alejandro Corichi, Parampreet Singh
A recent Comment [arXiv:0811.2790] on the Letter 'Quantum Bounce and Cosmic Recall' by the authors is shown to arise from an incorrect understanding of the issues at hand and of ou…
States and amplitudes for finite regions in a two-dimensional Euclidean quantum field theory
Daniele Colosi, Robert Oeckl
We quantize the Helmholtz equation (plus perturbative interactions) in two dimensions to illustrate a manifestly local description of quantum field theory. Using the general bounda…
Finite-size effects on a lattice calculation
Rafael G. Campos, Eduardo S. Tututi
We study in this paper the finite-size effects of a non-periodic lattice on a lattice calculation. To this end we use a finite lattice equipped with a central difference derivative…
Formation and Properties of Molecular Cloud Cores
Sami Dib, Roberto Galvan-Madrid, Jongsoo Kim +1
In this paper, we review some of the properties of dense molecular cloud cores. The results presented here rely on three-dimensional numerical simulations of isothermal, magnetized…
Is loop quantization in cosmology unique?
Alejandro Corichi, Parampreet Singh
We re-examine the process of loop quantization for flat isotropic models in cosmology. In particular, we contrast different inequivalent `loop quantizations' of these simple models…
Radio interferometric observations of candidate water-maser-emitting planetary nebulae
Jose F. Gomez, Olga Suarez, Yolanda Gomez +4
We present Very Large Array (VLA) observations of H2O and OH masers, as well as radio continuum emission at 1.3 and 18 cm toward three sources previously cataloged as planetary neb…
