Query: Marginally jammed states of hard disks in a one-dimensional channel   We have studied a class of marginally jammed states in a system of hard disks
confined in a narrow channel---a quasi-one-dimensional system---whose exponents
are not those predicted by theories valid in the infinite dimensional limit.
The exponent $\gamma$ which describes the distribution of small gaps takes the
value $1$ rather than the infinite dimensional value $0.41269\dots$. Our work
shows that there exist jammed states not found within the tiling approach of
Ashwin and Bowles. The most dense of these marginal states is an unusual state
of matter that is asymptotically crystalline.
