In this paper we revisit the isomorphism SU(2) ⊗ SU(2) ∼= SO(4) to apply to some subjects in Quantum Computation and Mathematical Physics. The unitary matrix Q by Makhlin giving the isomorphism as an adjoint action is studied and generalized from a different point of view. Some problems are also presented. In particular, the homogeneous manifold SU(2n)/SO(2n) which characterizes entanglements i...

متن کاملLocalized economic impact of sports stadium construction
A growing trend throughout the United States is an increasing willingness of cities to publicly finance professional sports stadiums. The stadiums are justified by tangible economic benefits, either citywide or specific to a targeted region through a revitalization plan. The citywide economic impact arising from a new professional sports stadium, when analyzed empirically, has been consistently...
متن کاملStadium billiard with moving walls.
We study the evolution of the energy distribution for a stadium with moving walls. We consider a one period driving cycle, which is characterized by an amplitude A and a wall velocity V. This evolving energy distribution has both "parametric" and "stochastic" components. The latter are important for the theory of quantum irreversibility and dissipation in driven mesoscopic devices. For an extre...
متن کاملSome dynamical properties of the stadium billiard
We consider the dynamical properties of one kind of cyclically ordered orbits of the stadium billiard. We prove that the stadium billiard possesses infinitely many such orbits, that they are hyperbolic, and that their stable and unstable manifolds intersect transversely. Hence the stadium billiard contains a Smale horseshoe. We construct symbolic dynamics for these orbits and consider their sen...
