The current understanding of the superconductor–insulator transition is discussed level by
level in a cyclic spiral-like manner. At the first level, physical phenomena and processes are …

The conventional theory of metals is in crisis. In the past 15 years, there has been an
unexpected sprouting of metallic states in low-dimensional systems, directly contradicting …

T he investigation of superconductivity in the presence of disorder began 60 years ago with
the work of Alexander Shal'nikov at the Institute for Physical Problems in Moscow. The …

We describe the nature of charge transport at nonzero temperatures (T) above the two-
dimensional (d) superfluid-insulator quantum-critical point. We argue that the transport is …

Providing an up-to-date and lucid presentation of phenomena across modern advanced-
level solid state physics, this new edition builds on an elementary understanding to …

Superconductor-insulator transitions, especially in thin films, can provide the simplest
examples of the continuous quantum phase transition paradigm. Quantum phase transitions …

The superconductor-insulator transition in ultrathin films of amorphous Bi has been tuned by
changing both film thickness and magnetic field on the same set of films. A thickness …

The critical temperature for the attractive Hubbard model on a square lattice is determined
from the analysis of two independent quantities, the helicity modulus ρ s and the pairing …

The superconductor-insulator transition of ultrathin films of bismuth, grown on liquid-helium-
cooled substrates, has been studied. The transition was tuned by changing both film …

The complex ac conductivity of thin highly disordered In O x films was studied as a function
of magnetic field through the nominal two-dimensional superconductor-insulator transition …
