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.
Loss in an auxiliary cavity induces nonreciprocal excitation exchange in a three-cavity quantum battery, yielding significantly higher steady-state energy in the battery than the charger.
Nonreciprocity combined with open boundaries and symmetry defects produces a domain-wall traveling-wave phase and anomalous chiral relaxation in open quantum systems.
Cross-Kerr coupling in the two-photon bosonic regime of a SQUID-coupled phase qubit never vanishes due to potential asymmetry and coupler nonlinearity, with explicit limits on the number of coherent states needed for the approximation.
In molecular optomechanical cavities the anti-Stokes sideband gives higher conversion efficiency under red detuning while the Stokes sideband amplifies the infrared signal under blue detuning, with added noise reaching the one-quantum limit in the amplification regime.
