Phase diagram characterized by transmission in a triangular quantum dot Project supported by the National Natural Science Foundation of China (Grant Nos. 11174228 and 10874132). |
Phase diagram on the t–V plane indicates the Kondo resonance state, the Coulomb blockade state, V-induced resonance state, and the orbital spin singlet. Here, Γ = 0.01, U = 0.1, t0 = 0.01, and ϵ = −U/2 − 2V. |
