We calculate the inelastic lifetime of an electron quasiparticle due to Coulomb interactions in an electron liquid at low (or zero) temperature in two and three spatial dimensions. The contribution of “exchange” processes ...

Erratum concerning Dynamical exchange-correlation potentials for an electron liquid [Phys. Rev. B 65, 235121 (2002)]

It has been known for some time that the exchange-correlation potential in time- dependent density functional theory is an intrinsically nonlocal functional of the density as soon as one goes beyond the adiabatic approximation. ...

The components of the exchange-correlation kernel tensor of an isotropic electron liquid in the spin channel have the structure f xc,2 L,T (q,v) ! q!0 A(v)/q21BL,T(v), where L denotes the longitudinal component and T the ...

We show that in order to calculate correctly the spin current carried by a quasiparticle in an electron liquid one must use an effective “spin mass” ms that is larger than both the band mass mb, which determines the charge ...

The imaginary parts of the exchange-correlation kernels fxcL,T(ω) in the longitudinal and transverse current-current response functions of a homogeneous electron liquid are calculated exactly at low frequency, to leading ...

It has been known for some time that the exchange-correlation potential in time- dependent density-functional theory is an intrinsically nonlocal functional of the density as soon as one goes beyond the adiabatic approximation. ...

We derive the spin-wave dynamics of a magnetic material from the time-dependent spin-density-functional theory in the linear response regime. The equation of motion for the magnetization includes, besides the static spin ...
