The buildup of a hidden state by applying a 35-fs laser pulse. (a) An abrupt drop of electrical resistance can be observed after a single 35-fs laser pulse, which can be attributed to the formation of a hidden state. (b) Representation of energy diagram presents the buildup of the hidden states. (c) The phase diagram after a 35-fs laser pulse. (a) was reproduced from Ref. [38] with permission.
