Semiclassical Analysis of the Wigner $12j$ Symbol with One Small Angular Momentum

, 2011
We derive an asymptotic formula for the Wigner $12j$ symbol, in the limit of one small and 11 large angular momenta. There are two kinds of asymptotic formulas for the $12j$ symbol with one small angular momentum.

Bilocal versus non-bilocal correlations in entanglement swapping experiments [PDF]

, 2011
Entanglement swapping is a process by which two initially independent quantum systems can become entangled and generate nonlocal correlations. To characterize such correlations, we compare them to those predicted by bilocal models, where systems that are

The square-kagome quantum Heisenberg antiferromagnet at high magnetic fields: The localized-magnon paradigm and beyond [PDF]

, 2013
We consider the spin-1/2 antiferromagnetic Heisenberg model on the two-dimensional square-kagome lattice with almost dispersionless lowest magnon band. For a general exchange coupling geometry we elaborate low-energy effective Hamiltonians which emerge ...

Systems of Hess-Appel'rot type

, 2006
We construct higher-dimensional generalizations of the classical Hess-Appel'rot rigid body system. We give a Lax pair with a spectral parameter leading to an algebro-geometric integration of this new class of systems, which is closely related to the ...

Physical Reach of a Neutrino Factory in the 2+2 and 3+1 Four-Family Scenario [PDF]

, 2001
We compare the physical reach of a Neutrino Factory in the 2+2 and 3+1 four-family models, with similar results in the two schemes; in both cases huge CP-violating effects can be observed with a near detector in the $\nu_\mu \to \nu_\tau$ channel.

Anchote (Coccinia abyssinica [Lam.] Cogn.) powder, an underutilized indigenous crop, as a substitute to commercial pectin in the production of strawberry jam

Heliyon, 2022
The study investigated the potential of anchote (Coccinia abyssinica [Lam.] Cogn.) tuber powder as a substitute to commercial pectin. Mixture D-optimal design was used to generate 14 experimental runs using ranges: strawberry fruit (45–55%), sugar (43–53%

Lie bialgebra contractions and quantum deformations of quasi-orthogonal algebras [PDF]

, 1994
Lie bialgebra contractions are introduced and classified. A non-degenerate coboundary bialgebra structure is implemented into all pseudo-orthogonal algebras $so(p,q)$ starting from the one corresponding to $so(N+1)$.

Family And Economic Growth In Poland

Folia Oeconomica Stetinensia, 2014
In the article we test the hypothesis that the weakening of family ties, as measured by the reduction in the number of marriages, a cascade of divorces and the decrease in the fertility rate, has brought about an economic slowdown in Poland.
