- Abstract: The grand canonical thermodynamics of a bosonic system is studied in order to
identify the footprint of its own high-density quantum phase transition. The
phases displayed by the system at zero temperature establish recognizable
patterns at finite temperature that emerged in the proximity of the boundary of
the equilibrium diagram. The gaped phase induces a state of
collectivism/condensation at finite temperature in which population cumulates
into the ground state in spite of interacting attractively. The work sets the
foundation to approach the effect of attraction in the formation of a molecular
condensate.

Topological phase transitions are found in a variety of systems and were shown to be deeply related with a thermodynamic description through scaling relations.

Polariton condensates occur away from thermal equilibrium, in an open system where heat and particles are continually exchanged with reservoirs.
We construct a few-level model that captures the main processes involved in the buildup of a ground-state population of polaritons.
This allows condensation to be understood as the output of a thermal machine and exposes the thermodynamic constraints on its occurrence.
