Transverse interactions in Dicke QBs induce collective spin squeezing for exponential coupling boost and act as nonlinear torque to guide optimal charging paths, remaining robust under dissipation and sometimes outperforming ideal cases.
Phase engineering in waveguide QED enables unidirectional remote charging of quantum batteries with independent control of nonreciprocity and storage efficiency across four emitter-waveguide configurations.
A two-level approximation predicts that bosonic atoms in a 1D trap form a faster quantum battery as particle number grows, with power scaling as the square root of the atom number.
Topology in a PT-symmetric SSH quantum battery produces an edge exceptional point at smaller gain-loss strength, yielding better transient and long-time charging, stored energy, and extractable work than the trivial configuration.
