DESCRIPTION:Speakers: John Henry Reina (Universidad del Valle)\nIn this ta
 lk\, we explore the superabsorption effect in quantum batteries\, which ex
 ploit collective quantum resources to surpass the limits of classical ener
 gy storage and power delivery. We analyse N-qubit cavity-coupled quantum b
 atteries governed by Dicke and Tavis-Cummings models under Gaussian drivin
 g and open-system dynamics. Finite-size scaling laws $O(N) \\sim N^\\alpha
 $ demonstrate an optimal region of relaxation and dephasing in which coher
 ent driving stabilises entanglement entropy growth for thermodynamic obser
 vables (maximum energy Emax\, charging time τ\, and maximum power Pmax) a
 nd for qubit and cavity entanglement entropies. The Dicke model exhibits e
 ntropy-suppressed extensive behaviour\, while the Tavis-Cummings model ach
 ieves super-extensive scaling ($\\alpha_{\\text{Emax}} \\in [1.08\,1.26]$\
 , $\\alpha_T \\simeq −0.49$\, $\\alpha_{\\text{Pmax}}\\in [1.57\,1.73]$)
 \, supported by qubit-cavity entanglement. \n\nWe demonstrate that dissipa
 tion can act as a stabiliser source\, yielding scaling benchmarks relevant
  to several experimental platforms. Our findings connect entanglement\, di
 ssipation-enhanced scaling laws\, and superabsorption\, outlining a pathwa
 y towards scalable quantum batteries that offer practical quantum advantag
