    "abstract": "A standard two-path interferometer fed into a linear N-port analyzer with\ncoincidence detection of its output ports is analyzed. The N-port is assumed to\nbe implemented as a discrete Fourier transformation $\\cal F$, i.e., to be\nbalanced. For unbound bosons it allows us to detect N-particle interference\npatterns with an N-fold reduction of the observed de Broglie wavelength,\nperfect visibility and minimal noise. Because the scheme involves heavy\nfiltering a lot of the signal is lost, yet, it is surprisingly robust against\ncommon experimental imperfections, and can be implemented with current\ntechnology.",
