Calculations of long-range three-body interactions for He()-He()-He()
Pei-Gen Yan, Li-Yan Tang, Zong-Chao Yan +1
We theoretically investigate long-range interactions between an excited state He atom and two identical state He atoms, for the cases of the three atoms all in spin singlet…
Panel collapse and its applications
Mark F. Hagen, Nicholas W. M. Touikan
We describe a procedure called panel collapse for replacing a CAT(0) cube complex by a "lower complexity" CAT(0) cube complex whenever contains a codimension-$2…
The loop quantum cosmology bounce as a Kasner transition
Edward Wilson-Ewing
For the Bianchi type I space-time (vacuum or with a massless scalar field), the loop quantum cosmology bounce can be viewed as a rapid transition between two classical solutions, w…
Natural Inflation from Polymer Quantization
Masooma Ali, Sanjeev S. Seahra
We study the polymer quantization of a homogeneous massive scalar field in the early universe using a prescription inequivalent to those previously appearing in the literature. Spe…
Roaring Bitmaps: Implementation of an Optimized Software Library
Daniel Lemire, Owen Kaser, Nathan Kurz +4
Compressed bitmap indexes are used in systems such as Git or Oracle to accelerate queries. They represent sets and often support operations such as unions, intersections, differenc…
On the Penrose inequality in anti-deSitter space
Viqar Husain, Suprit Singh
For asymptotically flat spacetimes the Penrose inequality gives an initial data test for the weak cosmic censorship hypothesis. We give a formulation of this inequality for asympto…
