Professor Hong clearly explained the phenomenon of Kondo-peak splitting occurring under the application of magnetic field and bias in a single-electron transistor with a quantum dot, which has not been explained until this work because no appropriate theory treating a strongly correlated system under nonequilibrium exists. Prof. Hong constructed a new nonperturbative dynamical theory that is good for treating nonequilibrium phenomenon of a single-electron transistor and found new resona
