A wide range of materials, like d-wave superconductors, graphene, and topological
insulators, share a fundamental similarity: their low-energy fermionic excitations behave as …

The problem of electron-electron interactions in graphene is reviewed. Starting from the
screening of long-range interactions in these systems, the existence of an emerging Dirac …

A range of quantum field theoretical phenomena driven by external magnetic fields and their
applications in relativistic systems and quasirelativistic condensed matter ones, such as …

Photodetectors are one of the most important components for a future “Internet-of-Things”
information society. Compared to the mainstream semiconductor-based photodetectors …

Due to its unique atom-thick 2D structure and remarkable physicochemical properties,
graphene has been making a profound impact in many areas of science and technology. In …

Graphene exhibits superior mechanical strength, high thermal conductivity, strong light–
matter interactions, and, in particular, exceptional electronic properties. These merits make …

A highly unconventional superconducting state with a spin-singlet $ d_ {x^ 2-y^ 2}\pm {\rm i}
d_ {xy} $-wave, or chiral d-wave symmetry has recently been suggested to emerge from …

The above question is frequently asked by theorists who are interested in graphene as a
model system, especially in context of relativistic quantum physics. We offer an experimental …

The electron states of gapped pseudospin-1 fermions of the α− T 3 lattice in the Coulomb
field of a charged impurity are studied. The free α− T 3 model has three dispersive bands …

The Coulomb interaction in systems of quasi-relativistic massless electrons has an
unscreened long-range component at variance with conventional correlated metals. We …
