The following simulations show how “bumps” will result in different final equilibrium states for three different loadings. Recall that for α < 1, the system is unstable. The loadings on the left two ...

In physics, there are four concepts of equilibrium. The first is stable equilibrium, which is like a helium balloon held by a child. When disturbed, it has the resilience to return to its original ...

A research team at Tohoku University has shown that a steady electric current can hold electron spins in positions that ...
