A simple ghost free and caustic free mimetic scalar field dark matter model
Published 5 Jul 2025 in gr-qc | (2507.05290v1)
Abstract: Chamseddine and Mukhanov have promoted the concept of mimetic dark matter as alternative dark matter candidate coming from gravitation. Unfortunately although being very interesting, their proposition turned out to have weakness among which ghost and caustic instabilities. In this paper I propose among the simplest ghost free and caustic free scalar field dark matter extension of their model; a proposition capable of challenging $\Lambda$CDM model or even capable of doing better.
