Dynamics of pinned quantized vortices in superfluid ${}^4$He in a microelectromechanical oscillator

Tomo Nakagawa, Makoto Tsubota, Keegan Gunther +1

We numerically studied the vortex dynamics at zero temperature in superfluid ${}^4$He confined between two parallel rough solid boundaries, one of which oscillates in a shear mode. T…
