The imaginary part of the non-equilibrium magnetic susceptibility of Ising spin glass in a transverse field under time- dependent longitudinal external magnetic field has been calculated at very low temperature on the basis of quantum droplet model and quantum linear response theory. Quantum and aging effects on the low temperature dynamics of the model are discussed. A comparison with recent theoretical and experimental data in spin glass is made.

Abstract
The imaginary part of the non-equilibrium magnetic susceptibility of Ising spin glass in a transverse field under time- dependent longitudinal external magnetic field has been calculated at very low temperature on the basis of quantum droplet model and quantum linear response theory. Quantum and aging effects on the low temperature dynamics of the model are discussed. A comparison with recent theoretical and experimental data in spin glass is made.File in questo prodotto:
