      abstract     = {We present a detailed analysis of the time series of
                      time-stamped neutron counts obtained by single-neutron
                      interferometry. The neutron counting statistics display the
                      usual Poissonian behavior, but the variance of the neutron
                      counts does not. Instead, the variance is found to exhibit a
                      dependence on the phase-shifter setting which can be
                      explained by a probabilistic model that accounts for
                      fluctuations of the phase shift. The time series of the
                      detection events exhibit long-time correlations with
                      amplitudes that also depend on the phase-shifter setting.
                      These correlations appear as damped oscillations with a
                      period of about 2.8 s. By simulation, we show that the
                      correlations of the time differences observed in the
                      experiment can be reproduced by assuming that, for a fixed
                      setting of the phase shifter, the phase shift experienced by
                      the neutrons varies periodically in time with a period of
                      2.8 s. The same simulations also reproduce the behavior of
                      the variance. Our analysis of the experimental data suggests
                      that time-stamped data of single-particle interference
                      experiments may exhibit transient features that require a
                      description in terms of non-stationary processes, going
                      beyond the standard quantum model of independent random
                      events.},
