Whereas in a normal system atoms spread out evenly across all available states as energy increases, leading to an increase in entropy, in a negative system the atoms begin to occupy the maximum possible energy state at the same time - leading entropy to decrease as energy increases. This is the point where you've reached negative temperature.

As one scientist put it, "the gas is not colder than zero Kelvin, but hotter. It is even hotter than at any positive temperature - the temperature scale simply does not end at infinity, but jumps to negative values instead."
