| Summary: | Analysis has been carried out on the interaction model of charger and quantum
batteries. The energy replenishment process was analyzed using the open
quantum system approach. Models of charger and quantum batteries use
harmonic oscillator models. This model was chosen because this model is
able to provide greater energy when compared to other battery models. The
dynamics of the interaction are determined using the master equation Lindblad
Master Equation by generating the equation of motion from the harmonic
oscillator operator charger-battery with the constant dephasing using the
ladder function approach. The energy equation is obtained by solving the
equation of motion to obtain the first momenta of the operator. The calculation
and modeling results show that in region I there is an interaction in close system
and in region II there is an interaction in open system. In the interaction
in region II, the energy produced is greater as a result of the assistance of
interaction with the environment. So it can be said that quantum batteries
have a better impact than conventional batteries.
