Generalized Heisenberg algebra from
Tea Martinic Bilac, Stjepan Meljanac, Salvatore Mignemi
It is well known that the algebra generates the conformal group, but it can also be used to define some variants of the Yang model of noncommutative geometry on a curved s…
Towards new relativistic doubly -deformed D=4 quantum phase spaces
Jerzy Lukierski, Stjepan Meljanac, Salvatore Mignemi +2
We propose new noncommutative models of quantum phase spaces, containing a pair of -deformed Poincaré algebras, with two independent double ()-deformations in spa…
Quantum mechanics of the nonrelativistic Yang model
S. Meljanac, S. Mignemi
We discuss, at leading order in , the quantum mechanics of a specific realization in phase space of the Yang model describing noncommutative geometry in a curved background.…
Dual -Minkowski spaces and -Poincaré algebras from Yang model and their Weyl realizations
T. MartiniÄ BilaÄ, S. Meljanac, S. Mignemi
We consider the Yang algebras isomorphic to and derive dual -Minkowski and -Poincaré algebras in terms of a metric . The corresponding Weyl rea…
Yang model revisited
S. Mignemi
A long time ago C.N. Yang proposed a generalization of the Snyder model to the case of a curved background spacetime, based on an algebra isomorphic to , which includes as…
Reduced Yang model and noncommutative geometry of curved spacetime
S. Meljanac, S. Mignemi
The Yang model describes a noncommutative geometry in a curved spacetime by means of an orthogonal algebra , whose 15 generators are identified with phase space variables a…
