Researchers discovered shear-induced anomalous stresses in field-responsive suspensions. This controllable phenomenon, involving competing fields and shear flow, offers new ways to tune soft condensed matter properties.

Area of Science:

  • Soft condensed matter physics
  • Rheology of complex fluids

Background:

  • Field-responsive suspensions exhibit unique behaviors under external stimuli.
  • Understanding stress generation in flowing complex fluids is crucial for material science.

Purpose of the Study:

  • To investigate shear-induced anomalous stresses in suspensions of bound dimers under competing fields.
  • To characterize the diverse stress regimes and their underlying mechanisms.

Main Methods:

  • Utilizing rheological measurements on suspensions of bound dimers with induced dipoles.
  • Applying controlled shear flow in the presence of a rotating external field.

Main Results:

  • Observed a multiplicity of anomalous stress behaviors, including nonmonotonic responses and negative viscosity.

  • Identified phenomena such as multiresonances and stress blockades.
  • Demonstrated the reversibility and self-similarity of stress transitions.

    • Conclusions:

    • The competition between rotating fields and shear flow induces complex rheological responses.
    • The controllable nature of these anomalous stresses allows for tuning macroscopic properties of soft matter.
    • This finding has potential applications in designing and manipulating soft condensed matter phases.
