Relativistic Spinning Particle and a New Non-commutative Spacetime
نویسنده
چکیده
The relativistic spinning particle model, recently proposed by Staruszkiewicz, is analyzed in a Hamiltonian framework. The model is heavily constrained and constraint analysis, in the Dirac scheme, is both novel and instructive. Our major finding is an associated noncommutative spacetime the structure of which is completely new. We have shown that this non-commutative phase space algebra is essential in revealing the spin effects in the particle model through the angular momentum generator and Hamiltonian equations of motion.

Noncommutativity in the mechanics of a free massless relativistic particle
We show the existence of a noncommutative spacetime structure in the context of a complete discussion on the underlying spacetime symmetries for the physical system of a free massless relativistic particle. The above spacetime symmetry transformations are discussed for the first-order Lagrangian of the system where the transformations on the coordinates, velocities and momenta play important ro...

متن کاملThermodynamics on Fuzzy Spacetime
We investigate the thermodynamics of non-relativistic and relativistic ideal gases on the spacetime with noncommutative fuzzy geometry. We first find that the heat capacities of the non-relativistic ideal boson and fermion on the fuzzy two-sphere have different values, contrast to that on the commutative geometry. We calculate the “statistical interparticle potential” therein and interprete thi...
متن کاملQuantum Mechanical Motion of Relativistic Particle in Non-Continuous Spacetime
The quantum mechanical motion of a relativistic particle in a noncontinuous spacetime is investigated. The spacetime model is a dense, rationale subset of two-dimensional Minkowski spacetime. Solutions of the Dirac equation are calculated using a generalized version of Feynman’s checkerboard model. They turn out to be closely related to the continuum propagator.
