Query: Strongly Interacting Bose Gases near a $d$-wave Shape Resonance   Many unconventional quantum matters, such as fractional quantum Hall effect
and $d$-wave high-Tc superconductor, are discovered in strongly interacting
systems. Understanding quantum many-body systems with strong interaction and
the unconventional phases therein is one of the most challenging problems in
physics nowadays. Cold atom systems possess a natural way to create strong
interaction by bringing the system to the vicinity of a scattering resonance.
Although this has been a focused topic in cold atom physics for more than a
decade, these studies have so far mostly been limited for $s$-wave resonance.
Here we report the experimental observation of a broad $d$-wave shape resonance
in degenerate ${}^{41}$K gas. We further measure the molecular binding energy
that splits into three branches as a hallmark of $d$-wave molecules, and find
that the lifetime of this many-body system is reasonably long at strongly
interacting regime. From analyzing the breathing mode excited by ramping
through this resonance, it suggests that a quite stable low-temperature atom
and molecule mixture is produced. Putting all the evidence together, our system
offers great promise to reach a $d$-wave molecular superfluid.
