(phys.org)—when three physicists first discovered through their calculations that a decaying atom moving through the vacuum experiences a friction-like force, they were highly suspicious. the results seemed to go against the laws of physics: the vacuum, by definition, is completely empty space and does not exert friction on objects within it. further, if true, the results would contradict the principle of relativity, since they would imply that observers in two different reference frames would see the atom moving at different speeds (most observers would see the atom slow down due to friction, but an observer moving with the atom would not).

researchers have studied ultrafast non-equilibrium magnetization in correlated spin systems in recent years. at both fundamental and application levels, ultrafast laser pulse excitation and dynamics measurement provide an effective path to fast optical detection, as well as control of magnetic order. studies have been conducted with magnetic media measuring the time-resolved magneto-optical kerr effect (tr-moke), ultrafast magnetic relaxation phenomenon such as ultrafast demagnetization and uniform precession. the optically excited magnetization precession in magnetic media exhibits the temporal response of magnetization when the effective magnetic field is instantaneously changed by ultrafast laser pulse excitation and provides information about the spin dynamics microscopically.
