Abstract Open quantum systems can be systematically controlled by making changes to their environment. A well-known example is the spontaneous radiative decay of an electronically excited emitter, such as atom or a molecule, which significantly influenced feedback from emitter’s environment, for example, presence reflecting surfaces. prerequisite deliberate control open system reveal physical mechanisms that determine its state. Here, we investigate Bose-Einstein condensation photonic Bose gas in environment with dissipation and feedback. Our measurements offer highly systematic picture under non-equilibrium conditions. We show adjusting frequency condensates naturally try avoid particle loss destructive interference In this way our experiments involved formation condensate, typically remain hidden when close thermal equilibrium.
