A collision between relativistic ions will sometimes, if the temperatures/energies of the particles are high enough, create a temporary state known as a quark-gluon plasma: where even individual ...

Researchers have demonstrated a way to maintain an unstable quantum system by applying bursts of microwave radiation. The technique is comparable to methods used for controlling an inverted pendulum ...

Upon a quench, namely a sudden change of the external conditions, a system is initially in a nonequilibrium state. The processes of relaxation to the new equilibrium state may be complex, specially if ...
