The doping or the alteration of crystals with guest species to obtain desired properties has
long been a research frontier in materials science. However, the closely packed lattice …

Moiré materials have emerged as a platform for exploring the physics of strong electronic
correlations and non-trivial band topology. Here we review the recent progress in …

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 progress in utilizing ultrafast light-matter interaction to control the macroscopic
properties of quantum materials is reviewed. Particular emphasis is placed on photoinduced …

The Hubbard model is the simplest model of interacting fermions on a lattice and is of similar
importance to correlated electron physics as the Ising model is to statistical mechanics or the …

Quantum particles on a lattice with competing long-range interactions are ubiquitous in
physics; transition metal oxides,, layered molecular crystals and trapped-ion arrays are a few …

The Tauc plot is a method originally developed to derive the optical gap of amorphous
semiconductors such as amorphous germanium or silicon. By measuring the absorption …

Strongly correlated systems can give rise to spectacular phenomenology, from high-
temperature superconductivity to the emergence of states of matter characterized by long …

The evolution of a Landau Fermi liquid into a non-magnetic Mott insulator with increasing
electronic interactions is one of the most puzzling quantum phase transitions in physics …

The Hubbard model, formulated by physicist John Hubbard in the 1960s, is a simple
theoretical model of interacting quantum particles in a lattice. The model is thought to …
