We demonstrate theoretically that the many-body effect such as exchange interaction can cause the hybridization of the electron and hole dispersion relations in InAs/GaSb based type II and broken-gap quantum well (QW) systems. As a result, a terahertz mini-gap at the anti-crossing points of the cond
