Query: Robust quantum sensing in strongly interacting systems with many-body
  scars   In most quantum sensing schemes, interactions between the constituent
particles of the sensor are expected to lead to thermalisation and degraded
sensitivity. However, recent theoretical and experimental work has shown that
the phenomenon of quantum many-body scarring can slow down, or even prevent
thermalisation. We show that scarring can be exploited for quantum sensing that
is robust against certain strong interactions. In the ideal case of perfect
scars with harmonic energy gaps, the optimal sensing time can diverge despite
the strong interactions. We demonstrate the idea with two examples: a spin-1
model with Dzyaloshinskii-Moriya interaction, and a spin-1/2 mixed-field Ising
model. We also briefly discuss some non-ideal perturbations, and the addition
of periodic controls to suppress their effect on sensing.
