    "abstract": "The quantum theory of Brownian motion is discussed in the Schwinger version\nwherein the notion of a coordinate moving forward in time $x(t)$ is replaced by\ntwo coordinates, $x_+(t)$ moving forward in time and $x_-(t)$ moving backward\nin time. The role of the doubling of the degrees of freedom is illustrated for\nthe case of electron beam two slit diffraction experiments. Interference is\ncomputed with and without dissipation (described by a thermal bath). The notion\nof a dissipative interference phase, closely analogous to the Aharonov-Bohm\nmagnetic field induced phase, is explored.",
