Dilatonic Brans-Dicke Anisotropic Collapsing Fluid Sphere And de Broglie Quantum Wave Motion

Two dimensional (2D) analogue of vacuum sector of the Brans Dicke (BD) gravity [1] is studied to obtain dynamics of anisotropic spherically symmetric perfect fluid. Our obtained static solutions behave as dark matter with state equation $\gamma =\frac{p(\rho )}{\varrho }=-0.25$ but in non-static regimes behave as regular perfect fluid with barotropic index $\gamma >0.$ Positivity property of total mass of the fluid causes that the BD parameter to be $\omega >\frac{2}{3}$ and/or $\omega <-1$. Locations of the event and apparent horizons of the collapsing fluid are obtained in its static regime. In case $\omega >0$ the apparent horizon is covered by event horizon where the cosmic censorship hypothesis is still valid. According to the model [1], we obtain de Broglie pilot wave of our metric solution which describes particles ensemble which become distinguishable via different values of $\omega \mathrm{.}$ Incident current density of particles ensemble on the horizons is evaluated which describe the Hawking radiation. The de Brogle -Bohm quantum potential effect is calculated also on the event (apparent) horizon which is independent (dependent) to values of $\omega \mathrm{.}$
