Rainbow Oppenheimer-Snyder collapse and the entanglement entropy production

The dust ball collapse is studied in the context of "rainbow metric" approach (where matter content supplemented with a scalar field perturbation) to Oppenheimer-Snyder scenario within framework loop quantum cosmology. global spacetime structure determined for this and subsequently used evaluate entanglement entropy via slight adaptation existing formulas. resulting model shown qualitatively resemble Reissner-Nordstr\"om black hole spacetime, particular, it still contains singularities, which allows us define only portions null infinity. consequence these results information loss paradox discussed. Furthermore, presence are discussion regarding viability selected scenario, assumption stationarity determine exterior metric.
