Riassunto (Italiano)
A Quantum Battery (QB) is a quantum system used to store and deliver energy where quantum or collective effects allow better performances in the delivery of energy then classical counterparts.
A Dicke Quantum Battery (DQB) is a kind of QB based on the Dicke model where supercharging is achieved, i.e. it is possible to transfer energy with superextensive power.
The aim of this Thesis is to further study the properties of a DQB in realistic scenarios. The role of dissipation, decoherence and detuning (between the charger and the battery) in the charging phase are studied in detail employing exact numerical diagonalization.
Lastly the so called "mean field" approximation usually used in literature to solve the dynamics of the Dicke model is discussed in a quantitative way.
