We review the dynamical mean-field theory of strongly correlated electron systems which is
based on a map** of lattice models onto quantum impurity models subject to a self …

A review of the basic ideas and techniques of the spectral density-functional theory is
presented. This method is currently used for electronic structure calculations of strongly …

The ordinary single-channel Kondo model consists of one or more spin-½ local moments
interacting antiferromagnetically with conduction electrons in a metal. This model has …

This paper reviews experimental evidence and the related theoretical background on exotic
phenomena arising from local quadrupolar degrees of freedom. Recent extensive studies on …

The multichannel Kondo model with SU (N) spin symmetry and SU (K) channel symmetry is
considered. The impurity spin is chosen to transform as an antisymmetric representation of …

Recent work is reviewed on continuous quantum phase transitions in impurity models, both
with fermionic and bosonic baths–these transitions are interesting realizations of boundary …

We present the universal theory of arbitrary, localized impurities in a confining paramagnetic
state of two-dimensional antiferromagnets with global SU (2) spin symmetry. The energy gap …

We present an extension of the noncrossing approximation (NCA), which is widely used to
calculate properties of Anderson impurity models in the limit of infinite Coulomb repulsion …

We introduce a representation of electron operators as a product of a spin-carrying fermion
and of a phase variable dual to the total charge (slave quantum rotor). Based on this …
