Deformed Quantum Phase Spaces, Realizations, Star Products and Twists
Stjepan Meljanac, Rina Štrajn
We review deformed quantum phase spaces and their realizations in terms of undeformed phase space. In particular, methods of calculation for the star product, coproduct of momenta…
Generalized Heisenberg algebra, realizations of the algebra and applications
Stjepan Meljanac, Zoran Škoda, Rina Štrajn
We introduce the generalized Heisenberg algebra appropriate for realizations of the algebra. Linear realizations of the algebra are presented…
Exponential Formulas, Normal Ordering and the Weyl-Heisenberg Algebra
Stjepan Meljanac, Rina Štrajn
We consider a class of exponentials in the Weyl-Heisenberg algebra with exponents of type at most linear in coordinates and arbitrary functions of momenta. They are expressed in te…
Snyder dynamics in a Schwarzschild spacetime
S. Mignemi, R. Strajn
We calculate the orbits of a particle in Schwarzschild spacetime, assuming that the dynamics is governed by a Snyder symplectic structure. With this assumption, the perihelion shif…
Generalized Poincare algebras, Hopf algebras and kappa-Minkowski spacetime
D. Kovacevic, S. Meljanac, A. Pachol +1
We propose a generalized description for the kappa-Poincare-Hopf algebra as a symmetry quantum group of underlying kappa-Minkowski spacetime. We investigate all the possible implem…
