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 …

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 …

The pseudogap Kondo problem, describing a magnetic impurity embedded in an electronic
environment with a power-law density of states, displays continuous quantum phase …

Rare-earth intermetallic alloys and compounds, in particular those with Ce or Yb, are often
close to a magnetic instability. In particular, CeCu6− xAux has become a prototype heavy …

It took several years after the idea of a zero-temperature phase transition emerged to realize
the impact of such a quantum critical point over a large region of the phase diagram …

From the crystalization of water into snowflakes, the alignment of electron spins in a
ferromagnet, the emergence of superconductivity in a cooled metal, to the very formation of …
