'Conventional'superconductivity, as used in this review, refers to electron–phonon-coupled
superconducting electron pairs described by BCS theory. Unconventional superconductivity …

In materials with strong local Coulomb interactions, simple defects such as atomic
substitutions strongly affect both macroscopic and local properties of the system. A …

The transport of a small amount of liquid on a solid is not a simple process, owing to the
nature of the contact between the two phases. Setting a liquid droplet in motion requires non …

Polyhydrides are a novel class of superconducting materials with extremely high critical
parameters, which is very promising for sensor applications. On the other hand, a complete …

Underdoped high-Tc superconductors are frequently characterised by a temperature, T*,
below which the normal-state pseudogap opens. Two different “phase diagrams” based on …

Small changes in an external parameter can often lead to dramatic qualitative changes in
the lowest energy quantum mechanical ground state of a correlated electron system. In …

Magnetic interactions and magnetic impurities are destructive to superconductivity in
conventional superconductors. By contrast, in some unconventional macroscopic quantum …

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 …

This article summarizes our understanding of the Kondo effect in graphene, primarily from a
theoretical perspective. We shall describe different ways to create magnetic moments in …

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 …
