The appearance of the Planckian time τ Pl= ℏ/k BT is reviewed in both conventional and
unconventional metals. A pedagogical discussion of the various different timescales …

Cuprates exhibit exceptionally strong superconductivity. To understand why, it is essential to
elucidate the nature of the electronic interactions that cause pairing. Superconductivity …

Superconductivity develops in metals upon the formation of a coherent macroscopic
quantum state of electron pairs. Iron pnictides and chalcogenides are materials that have …

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

The three central phenomena of cuprate (copper oxide) superconductors are linked by a
common doping level p*—at which the enigmatic pseudogap phase ends and the resistivity …

Whether a quantum critical point (QCP) lies beneath the superconducting dome has been a
long-standing issue that remains unresolved in many classes of unconventional …

We consider a low T c metallic superconductor weakly coupled to the soft fluctuations
associated with proximity to a nematic quantum critical point (NQCP). We show that (1) a …

Using determinantal quantum Monte Carlo, we compute the properties of a lattice model
with spin 1 2 itinerant electrons tuned through a quantum phase transition to an Ising …

In the quest for superconductors with higher transition temperatures (T c), one emerging
motif is that electronic interactions favorable for superconductivity can be enhanced by …

Many exotic metallic systems have a resistivity that varies linearly with temperature, and the
physics behind this is thought to be connected to high-temperature superconductivity in the …
