Non-standard quantum so(2,2) and beyond
A new “non-standard” quantization of the universal enveloping algebra of the split (natural) real form so(2, 2) of D2 is presented. Some (classical) graded contractions of so(2, 2) associated to a Z2 × Z2 grading are studied, and the automorphisms defining this grading are generalized to the quantum case, thus providing quantum contractions of this algebra. This produces a new family of “non-st...
متن کاملBeyond Standard Quantum Chromodynamics
Despite the many empirical successes of QCD, there are a number of intriguing experimental anomalies that have been observed in heavy avor hadroproduc-tion, in measurements of azimuthal correlations in deep inelastic processes, and in measurements of spin correlations in hadronic reactions. Such phenomena point to color coherence and multiparton correlations in the hadron wavefunc-tions and phy...

متن کاملNon-standard Quantum Groups and Superization
We obtain the universal R-matrix of the non-standard quantum group associated to the Alexander-Conway knot polynomial. We show further that this nonstandard quantum group is related to the super-quantum group Uqgl(1|1) by a general process of superization, which we describe. We also study a twisted variant of this non-standard quantum group and obtain, as a result, a twisted version of Uqgl(1|1...
متن کاملNon-Orthomodular Models for Both Standard Quantum Logic and Standard Classical Logic: Repercussions for Quantum Computers
It is shown that propositional calculuses of both quantum and classical logics are noncategorical. We find that quantum logic is in addition to an orthomodular lattice also modeled by a weakly orthomodular lattice and that classical logic is in addition to a Boolean algebra also modeled by a weakly distributive lattice. Both new models turn out to be non-orthomodular. We prove the soundness and...
