![]() 32 For many applications in granular or soft matter physics, achieving net horizontal motion of individual particles is desirable. 1,29 It has been shown that directed horizontal motion of passive bouncers can be achieved by breaking the symmetry of the vibration, 30 the individual particles, 31 or the impact surface. ![]() 1,26–29 In particular, it has recently been demonstrated in both experiment and theory that a concave impact surface can actually destabilize purely vertical bouncing and result in persistent horizontal motion of the ball. ![]() 10–25 Some extensions of the 1D case have focused on multiple spatial dimensions where the ball is not physically constrained in the horizontal direction and bounces on a non-flat topography. 9 The one-dimensional problem, wherein the ball bounces vertically on a flat platform in a gravitational field, is the scenario most frequently explored in the literature. The basic physical system is conceptually simple yet exhibits surprisingly rich dynamical behaviors. This problem has been investigated for decades and still constitutes an active area of research. This complex fluid system is reminiscent of the celebrated bouncing ball problem, wherein a ball bounces repeatedly on a vibrating rigid platform.
