Efficiency Fluctuations in a Quantum Battery Charged by a Repeated Interaction Process

“…Repeated interaction schemes, also known as collisional models [ 1 , 2 , 3 , 4 , 5 , 6 ], have played a vital role in the development of quantum optics [ 7 , 8 , 9 , 10 ] and the rapid evolution of quantum thermodynamics [ 11 , 12 , 13 , 14 , 15 ]. The idealized and straightforward formalism has been crucial to designing and understanding quantum devices such as information engines [ 16 , 17 , 18 , 19 ], heat engines [ 12 , 20 , 21 , 22 , 23 ], and quantum batteries [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. Recently, it was realized that the framework can be extended to deal with macroscopic reservoirs [ 23 , 35 ], expanding the reach of applications in quantum thermodynamics.…”

“…INTRODUCTIONRepeated interaction schemes, a.k.a collisional models [1-6], have played a vital role in the development of quantum optics [7-10] and the rapid evolution of quantum thermodynamics [11][12][13][14][15]. The idealized and straightforward formalism has been crucial to designing and understanding quantum devices such as information engines [16][17][18][19], heat engines [12,[20][21][22][23], and quantum batteries [24][25][26][27][28][29][30][31][32][33].
