Query: Quasilinear quantum magnetoresistance in pressure-induced nonsymmorphic
  superconductor CrAs   In conventional metals, modification of electron trajectories under magnetic
field gives rise to a magnetoresistance that varies quadratically at low field,
followed by a saturation at high field for closed orbits on the Fermi surface.
Deviations from the conventional behaviour, e.g. the observation of a linear
magnetoresistance, or a non-saturating magnetoresistance, have been attributed
to exotic electron scattering mechanisms. Recently, linear magnetoresistance
has been observed in many Dirac materials, in which the electron-electron
correlation is relatively weak. The strongly correlated helimagnet CrAs
undergoes a quantum phase transition to a nonmagnetic superconductor under
pressure. Near the magnetic instability, we observe a large and non-saturating
quasilinear magnetoresistance from the upper critical field to 14 T at low
temperatures. We show that the quasilinear magnetoresistance arises from an
intricate interplay between a nontrivial band crossing protected by
nonsymmorphic crystal symmetry and strong magnetic fluctuations
