    "abstract": "We study the connection between dissipation and reality in macroscopic\nquantum systems. We present the following scenario; if we consider the dynamics\nof a `partial\u0027 wave function, the dissipation is represented as a nonlocal term\nand it causes destructive interference to suppress the quantum fluctuation.\nUsing the variational method, we confirm that this dissipation term is a\nreasonable extension of the standard (Schr\\\"odinger) description for isolated\nsystems, from which we also derive the classical action. Consequently, in\nmacroscopic systems, the states whose time-integrated dissipation takes an\nextreme value come true. This description, which is consistent with our sense\nof reality, coexists with the usual linear-time-dependent description.",
