In recent years we have examined various quantum mechanisms that may boost the performance of heat machines: squeezed baths, coherent pistons, Dicke cooperative working media and more. Yet all these mechanisms have classical analogs. More fundamentally, none of them can be described unitarily: all heat machines to date are dissipative open systems. We have now broken away from this paradigmatic description of heat machines and suggest instead few-mode coherent nonlinear systems that are describable unitarily but act as genuine heat machines. Their simplest version is a nonlinear Mach-Zehnder interferometer, which allows the bridging of thermodynamic and properly quantum descriptions.
