abstract

In this work we shall explore the effects of non commutativity in fractional classical and quantum schemes using the flat Friedmmann-Robertson-Walker (FRW) cosmological model coupled to a scalar field in the K-essence formalism. In previous work we have obtained the commutative solutions in both regimes into the fractional framework. Here we introduce noncommutative variables, considering that all minisuperspace variables $\rm q^i_{nc}$ do not commute, so the symplectic structure was modified. In the quantum regime, the probability density presents new structure in the scalar field corresponding to the value of the non-commutative parameter, in the sense that this probability density undergoes a shift back to the direction of the scale factor, causing classical evolution to arise earlier than in the commutative world.

  1. Fractional Schwarzschild-Tangherlini black hole with a fractal event horizon

    gr-qc 2025-06 reject novelty 4.0 of 10

    A fractional Wheeler-DeWitt equation yields D-dimensional Schwarzschild-Tangherlini black holes, with the horizon called fractal and the temperature set by an arbitrary parameter alpha.
