Atomically thin transition metal dichalcogenides (TMDs) are 2D semiconductors with tightly
bound excitons and correspondingly strong light–matter interactions. Owing to the weak van …

The basic aspects of electrons in graphene (two-dimensional graphite) exposed to a strong
perpendicular magnetic field are reviewed. One of its most salient features is the relativistic …

While regular flat bands are good for enhancing the density of states and hence the gap,
they are detrimental to the superfluid weight. We show that the predicted nontrivial topology …

Topological invariants built from the periodic Bloch functions characterize new phases of
matter, such as topological insulators and topological superconductors. The most important …

Presenting the physics of the most challenging problems in condensed matter using the
conceptual framework of quantum field theory, this book is of great interest to physicists in …

A spatially indirect exciton is created when an electron and a hole, confined to separate
layers of a double quantum well system, bind to form a composite boson,. Such excitons are …

An exciton condensate is a Bose–Einstein condensate of electron and hole pairs bound by
the Coulomb interaction,. In an electronic double layer (EDL) subject to strong magnetic …

An exciton is the particle-like entity that forms when an electron is bound to a positively
charged 'hole'. An ordered electronic state in which excitons condense into a single …

Coulomb drag is a transport phenomenon whereby long-range Coulomb interaction
between charge carriers in two closely spaced but electrically isolated conductors induces a …

If bosonic particles are cooled down below the temperature of quantum degeneracy, they
can spontaneously form a coherent state in which individual matter waves synchronize and …
