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 …

Recent studies of the electromagnetic response of high-T c superconductors using terahertz,
infrared, and optical spectroscopies are reviewed. In combination these experimental …

The discovery of superconducting H3S with a critical temperature T c∼ 200 K opened a
door to room temperature superconductivity and stimulated further extensive studies of …

The development of colloidal quantum dots has led to practical applications of quantum
confinement, such as in solution-processed solar cells, lasers and as biological labels …

One of the first theoretical proposals for understanding high-temperature superconductivity
in the cuprates was Anderson's RVB theory using a Gutzwiller projected BCS wavefunction …

The possibility of high, room-temperature superconductivity was predicted for metallic
hydrogen in the 1960s. However, metallization and superconductivity of hydrogen are yet to …

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 …

An ansatz is proposed for the coherent part of the single particle Green's function in a doped
resonant valence bond (RVB) state by analogy with the form derived by Konik and co …

We review recent experimental and theoretical results on the interaction between single-
particle excitations and collective spin excitations in the superconducting state of high-Tc …

The capability to control the type and amount of charge carriers in a material and, in the
extreme case, the transition from metal to insulator, is one of the key challenges of modern …
