| contents | We study a repulsive thermal system governed by odd interactions. The interplay between oddness and inertia induces a non-equilibrium phase transition from a homogeneous to a non-homogeneous phase, characterized by bubbles induced by odd interactions. This phenomenon occurs in the absence of attractions and is generated by the competition between the standard pressure contribution due to particle repulsion and an effective surface tension generated by odd-induced centrifugal forces. As a signature of the phase transition, the system exhibits vortex structures and oscillating spatial velocity correlations, which emerge close to the analytically predicted transition point. Our findings can be verified in granular experiments governed by odd interactions, such as spinners and colloidal magnets, and could be key to characterizing the emerging properties of metamaterials. |
