The Quantum Deformed Dirac Equation from the k-Poincare` Algebra
Anatol Nowicki, Emanuele Sorace, Marco Tarlini
In this letter we derive a deformed Dirac equation invariant under the k-Poincare` quantum algebra. A peculiar feature is that the square of the k-Dirac operator is related to the…

Heisenberg XXZ Model and Quantum Galilei Group
F. Bonechi, E. Celeghini, R. Giachetti +2
The 1D Heisenberg spin chain with anisotropy of the XXZ type is analyzed in terms of the symmetry given by the quantum Galilei group Gamma_q(1). We show that the magnon excitations…
