A geometric perspective on singularity resolution and uniqueness in loop quantum cosmology

Alejandro Corichi, Parampreet Singh

We re-examine the issue of singularity resolution in homogeneous loop quantum cosmology from the perspective of geometrical entities such as expansion rate and the shear scalar. Th…

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…

Spatially asymptotic S-matrix from general boundary formulation

Daniele Colosi, Robert Oeckl

We construct a new type of S-matrix in quantum field theory using the general boundary formulation. In contrast to the usual S-matrix the space of free asymptotic states is located…

A note on the least totient of a residue class

M. Z. Garaev

Let be a large prime number, be any integer, be a fixed small positive quantity. Friedlander and Shparlinksi \cite{FSh} have shown that there exists a positive integer…
