We use time-dependent spin-density-functional theory to study dynamical magnetic phenomena. First, we recall that the local-spin-density approximation (LSDA) fails to account correctly for magnetic fluctuations in the paramagnetic state of iron and o

Using a method suggested by Zhang, Carlson and Gubernatis, we have formulated an auxiliary-field method for the electron gas (jellium) in the form of a random walk through the space of Slater determinants. A calculation on a model jellium shows that

We have written a version of the Hubbard-Stratonovich transformation for the case of the relativistic jellium, and have developed an auxiliary-field method for performing a quantum Monte Carlo calculation on such a system. We have successfully applie

Relativistic potential scattering from non-spherically symmetric scatterers is studied and expressions for both charge and magnetization density are derived. The validity of full potential Korringer-Kohn-Rostoker (KKR) multiple-scattering theory for

The modern first-principles theory of the electronic structure in ordered and random substitutional alloys will be reviewed with special reference to magnetic fluctuations on total energy calculations. Then, a variety of approaches to predicting allo

The magnetic behaviour of FCC superlattices of equal-thickness Ni and Fe layers, with repeat lengths between 6 and 30 atomic layers, and with layers parallel to both 111 and 100 crystal planes, is modelled with a short range interaction Ising model,

Using a first-principles, relativistic electronic structure theory of finite temperature metallic magnetism, we investigate the variation of magnetic anisotropy K with magnetization M in metallic ferromagnets. We apply the theory to the high uniaxial

We revisit the old problem of exotic superconductivity as Cooper pairing with finite angular momentum emerging from a central potential. Based on some general considerations, we suggest that the phenomenonn is associated with interactions that keep e

We study a simple BCS-like model which describes unconventional superconductivity on the basis of an electron-electron attraction corresponding to the delta-shell potential: $U(r) = -g \delta(r-r_0)$. It predicts a $T_c$ vs. doping behavior similar t
