An important goal of modern condensed-matter physics involves the search for states of
matter with emergent properties and desirable functionalities. Although the tools for material …

Light–matter interaction in 2D and topological materials provides a fascinating control knob
for inducing emergent, non-equilibrium properties and achieving new functionalities in the …

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 …

Although copper oxide high-temperature superconductors constitute a complex and diverse
material family, they all share a layered lattice structure. This curious fact prompts the …

Terahertz (THz) light has proven to be a fine tool to probe and control quasi-particles and
collective excitations in solids, to drive phase transitions and associated changes in material …

Recent advances in laser technology have made it possible to generate of precisely shaped
strong-field pulses at terahertz frequencies. These pulses are especially useful to selectively …

Light-induced supercurrents chart a path forward for the electromagnetic design of emergent
materials phases and collective modes for quantum engineering applications. However …

Harmonic generation is a general characteristic of driven nonlinear systems, and serves as
an efficient tool for investigating the fundamental principles that govern the ultrafast …

The Higgs mechanism, ie, spontaneous symmetry breaking of the quantum vacuum, is a
cross-disciplinary principle, universal for understanding dark energy, antimatter and …

The defining characteristic, of Cooper pairs with finite centre-of-mass momentum is a
spatially modulating superconducting energy gap Δ (r), where r is a position. Recently, this …
