In this letter, we derive the path integral action of a particle in κ-Minkowski spacetime. The equation of motion for an arbitrary potential due to the κ-deformation of the Minkowski spacetime is then obtained. The action contains a dissipative term which owes its origin to the κ-Minkowski deformation parameter a. We take the example of the harmonic oscillator and obtain the frequency of oscillations in the path integral approach as well as the operator approach up to the first order in the…

Generalized Dirac oscillator with κ-Poincaré algebra

In this paper, the generalized Dirac oscillator with κ-Poincare algebra is structured by replacing the momentum operator p with p − imωβV (r)r in κ-deformation Dirac equation. The deformed radial e...

Classical and Quantum Mechanics of Free κ-Relativistic Systems

We consider the Hamiltonian and Lagrangian formalism describing free κ-relativistic particles with their four-momenta constrained to the κ-deformed mass shell. We study the formalism with commuting

Path-integral action of a particle in the noncommutative plane.

A coherent state approach to the path-integral representation of the transition amplitude of the free particle and harmonic oscillator is formulated and it is found that this action is nonlocal in time.

Path integral action of a particle in a magnetic field in the noncommutative plane and the Aharonov–Bohm effect

The formulation of noncommutative quantum mechanics as a quantum system represented in the space of Hilbert–Schmidt operators is used to systematically derive, using the standard time slicing

κ-Minkowski spacetime and the star product realizations

We investigate a Lie algebra-type κ-deformed Minkowski spacetime with undeformed Lorentz algebra and mutually commutative vector-like Dirac derivatives. There are infinitely many realizations of

Quantum symmetry, the cosmological constant and Planck scale phenomenology

We present a simple algebraic mechanism for the emergence of deformations of Poincar? symmetries in the low-energy limit of quantum theories of gravity. The deformations, called ?-Poincar? algebras,

Feynman Path Integral on the Noncommutative Plane

. We formulate Feynman path integral on a non commutative plane using coherent states. The propagator for a free particle exhibits UV cut-off induced by the parameter of non commutativity.
