The TS section of QUAGRAP is pursuing various lines of research in the field of quantum gravity phenomenology. An important development concerns the theory and phenomenology of regular black holes and other "black hole mimickers," with or without horizons. Another area of interest is the phenomenology of quantum gravity in scenarios of deformed special relativity, with a new geometric description based on the cotangent bundle or violated at high energies. In recent years, research has focused on the resilience of thermodynamic properties of black holes in the context of Horava's gravity theory.
A natural context for simulating quantum phenomena in spacetimes of this type is analog gravity. This research area aims to simulate field theory phenomena in curved spaces in laboratories, through the study of condensed matter systems, such as Bose-Einstein condensates. These systems have also been explored as "toy models" for emergent gravity systems, allowing a reevaluation of open questions, such as the quantum information loss paradox in black holes.
Finally, another active research area concerns a framework in which dark matter develops a non-minimal coupling similar to Horndeski in galactic disks, demonstrating the success of the theory in reproducing observed rotation curves and density profiles.
