We theoretically study the coherent pseudo-spin dynamics in Aharonov-Bohm interferometer containing laterally coupled double quantum dots (DQDs). We propose a novel blockade mechanism in laterally coupled DQDs suffering from a quantum interference effect. The leakage current due to the coherent pseu
