Periodically driven many-body quantum battery

AI-discovery of a new charging protocol in a micromaser quantum battery

“…The first work on the subject was by Alicki and Fannes [14], after which subsequent research works extended in several different directions. These include the proposal of explicit theoretical models of quantum batteries [15][16][17][18][19][20][21] and the analysis of the figures of merit to address the efficiency of such devices, such as the charging power [22,23], the maximum amount of energy which can be unitarily extracted [24][25][26], the effect of noise and imperfections [27][28][29][30], non-markovian effects [31,32], stability and fluctuations properties [33] or the necessary conditions to achieve a quantum charging advantage [34][35][36].…”

Lossy Micromaser Battery: Almost Pure States in the Jaynes–Cummings Regime

“…Recently, collision models have been used to describe the charging process of quantum batteries [ 13 , 14 , 15 , 16 , 24 , 25 ], that is, of quantum mechanical systems suitable to store energy in some excited states [ 15 , 16 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 ], to be later released on demand. The charging of the battery, modeled by a quantum harmonic oscillator or a large spin, via sequential interactions (collisions) with a stream of qubits, has exhibited enhanced performances with respect to classical counterpart, when the qubits are prepared in some coherent state, with respect to the classical, incoherent charging [ 15 , 16 ].…”

Micromasers as quantum batteries

“…Starting from the seminal work of Alicki and Fannes, [9], several figures of merit, to characterize the performance of a quantum battery, have been introduced and studied. These include energy storage [10][11][12][13][14], work extraction [9,15], fluctuations properties [16][17][18][19] and charging power [4][5][6][20][21][22][23][24][25][26][27][28][29][30][31][32][33], to name some of them.…”
