Symmetrically pulsating bubbles swim in an anisotropic fluid by nematodynamics
Abstract Swimming in low-Reynolds-number fluids requires the breaking of time-reversal symmetry and centrosymmetry.Microswimmers, often with asymmetric shapes, exhibit Size Max X nonreciprocal motions or exploit nonequilibrium processes to propel.The role of the surrounding fluid has also attracted attention because viscoelastic, non-Newtonian, and
