During retrovirus maturation, cleavage of the precursor structural Gag polyprotein by the
viral protease induces architectural rearrangement of the virus particle from an immature into …

The optical bistability (OB) in the quantum dot molecules with four energy levels in a
unidirectional ring cavity has been investigated. The authors find that the OB behaviour in …

The optical bistability of a quantum dot molecule system under tunneling and coupling laser
excitations is investigated. It is found that the hysteresis loop, threshold, appearance and …

Optical multistablity (OM) and bistability (OB) are investigated theoretically in the four-level
cascade quantum wells (QWs) with two similar transitions for the probe laser. It is interesting …

The optical bistability (OB) in the quantum dot (QD) biexciton–exciton cascaded scheme in a
unidirectional ring cavity has been investigated. We find that the OB behavior in our system …

We have theoretically studied the optical bistability behaviors under an external electric field
and a coupling laser field in double quantum dot molecule system with π-type four energy …
