The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

We review the physics of pair-density wave (PDW) superconductors. We begin with a
macroscopic description that emphasizes order induced by PDW states, such as charge …

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

The spectral energy gap is an important signature that defines states of quantum matter:
insulators, density waves and superconductors have very different gap structures. The …

At very high do** levels the van Hove singularity in the π* band of graphene becomes
occupied and exotic ground states possibly emerge, driven by many-body interactions …

Upon introducing charge carriers into the copper–oxygen sheets of the enigmatic lamellar
cuprates, the ground state evolves from an insulator to a superconductor and eventually to a …

The term'high-temperature superconductor'used to refer only to copper-based compounds—
now, iron-based pnictides have entered the frame. The comparison of these two types of …

High harmonic generation of ultrafast laser pulses can be used to perform angle-resolved
photoemission spectroscopy (ARPES) to map the electronic band structure of materials with …

Close to optimal do**, the copper oxide superconductors show 'strange metal'behaviour,,
suggestive of strong fluctuations associated with a quantum critical point,,,. Such a critical …

This paper examines the way of thinking and limitations of physicists regarding the
phenomenon of superconductivity and outlines how room-temperature and ambient …
