We use the thermo-mechanical effect to create a chemical potential difference between two liquid reservoirs connected to each other through Vycor rods in series with solid hcp 4He to confirm that a DC flux of atoms takes place below 600 mK, but find that the flux falls abruptly in the vicinity of 80 mK. It is impossible to add density to a solid freshly made at 60 mK and samples freshly made at 60 mK do not allow mass flux, even when raised in temperature to 200 mK. Solids created above 300 mK and cooled to 60 mK accept added …

We demonstrate the existence of a new kind of non-pairwise multivortex interaction forces, which are present between superconducting vortices along with pairwise vortex interactions. We show that the multibody forces are especially important in compact vortex clusters in two-component type-1.5 superconductors and result in extremely rich physics of multivortex bound states.
