Gaussian approximations for the exchange-energy functional of current-carrying states: Applications to two-dimensional systems
S. Pittalis, E. Rasanen, E. K. U. Gross
Electronic structure calculations are routinely carried out within the framework of density-functional theory, often with great success. For electrons in reduced dimensions, howeve…

Chiral two-dimensional electron gas in a periodic magnetic field
Mathieu Taillefumier, Vitalii Dugaev, Benjamin Canals +2
We study the energy spectrum and electronic properties of two-dimensional electron gas in a periodic magnetic field of zero average with a symmetry of triangular lattice. We demons…
