A team of researchers from the University of Exeter and Piazza Leonardo da Vinci, has shown, theoretically, that corkscrew elastic waves carry well-defined orbital angular momentum. In their paper published in the journal Physical Review Letters, the group describes experiments they conducted with aluminum pipe and simulations they built that showed the possibility of using waves of vibration moving along the walls of a pipe in new types of applications.
