Query: Generic quantized zero-bias conductance peaks in
  superconductor-semiconductor hybrid structures   We show theoretically that quantized zero-bias conductance peaks should be
ubiquitous in superconductor-semiconductor hybrids by employing a
zero-dimensional random matrix model with continuous tuning parameters. We
demonstrate that a normal metal-superconductor (NS) junction conductance
spectra can be generically obtained in this model replicating all features seen
in recent experimental results. The theoretical quantized conductance peaks,
which explicitly do not arise from spatially isolated Majorana zero modes, are
easily found by preparing a contour plot of conductance over several
independent tuning parameters, mimicking the effect of Zeeman splitting and
voltages on gates near the junction. This suggests that, even stable apparently
quantized conductance peaks need not correspond to isolated Majorana modes;
rather, the $\textit{a priori}$ expectation should be that such quantized peaks
generically occupy a significant fraction of the high-dimensional tuning
parameter space that characterizes the NS tunneling experiments.
