As we mark the centenary of Albert Einstein's seminal contribution to both quantum mechanics and special relativity, we approach another anniversary — that of Einstein's foundation of the quantum theory of solids. But 100 years on, the same experimental measurement that puzzled Einstein and his contemporaries is forcing us to question our understanding of how quantum matter transforms at ultra-low temperatures.

Holographic Quantum Matter (2016, background): “A ubiquitous property of the higher temperature superconductors (found in the cuprates, the pnictides, and related compounds) is an anomalous ‘strange metal’ state found at temperatures, T , above the superconducting critical temperature, Tc [654].”
Observation of the Dirac fluid and the breakdown of the Wiedemann-Franz law in graphene (2015, background): “The Dirac fluid shares many features with quantum critical systems [13]: most importantly, the electron-electron scattering time is fast [14–17], and well suited to a hydrodynamic description.”
The physics of quantum materials (2017, background): “Do they predominantly entangle electrons on nearest-neighbour lattice sites, or is the long-range entanglement generically associated with quantum phase transitions between diﬀerent forms of collective order 56 (Fig.”
Lectures on hydrodynamic fluctuations in relativistic theories (2012, background): “Instead, the studies were heavily motivated by the recent experiments studying the quark-gluon plasma [18], by the gauge-gravity duality [19, 20], and by the progress in understanding quantum critical phenomena [21].”
Quantum criticality in heavy-fermion metals (2007, background): “order phase transition is the quantum critical point (QCP).(2,3) The quantum critical state is distinct from the phases on both sides, and is expected to display features in its physical properties that are universal.”
What Can Gauge-Gravity Duality Teach Us about Condensed Matter Physics? (2011, background): “An exotic class of compressible states have emerged in condensed matter studies motivated by the strange metal problem of correlated electron systems [20].”
Fermi gases in one dimension: From Bethe ansatz to experiments (2013, background): “However, understanding the various aspects of quantum criticality in quantum systems represents a major challenge to our knowledge of many-body physics (Coleman and Schofield, 2005; Gegenwart et al., 2008; Löhneysen et al., 2007; Sachdev and Keimer, 2011; Sondhi et al., 1997; Vojta, 2003).”
Colloquium: Hidden order, superconductivity, and magnetism: The unsolved case of URu 2 Si 2 (2011, background): “For example, in the overview article of Coleman and Schofield (2005) it appears to mask the quantum phase transition in Sr2Ru3O7 where a putative nematic phase has replaced the HO one.”
Transport in inhomogeneous quantum critical fluids and in the Dirac fluid in graphene (2015, background): “Fermi liquid theory is known to fail in a variety of experimentally realized metals in two or more spatial dimensions – most famous among these is the strange metal phase of the cuprate superconductors [15, 16, 17] which does not have quasiparticle excitations.”
