Ferroelectromagnets - compounds with ferroelectric and magnetic orderings - were discovered about fifty years ago. They are of great interest due to the possibility of mutual control of electric (magn . . . . .

Linear scaling methods, or O(N) methods, have computational and memory requirements which scale linearly with the number of atoms in the system, N, in contrast to standard approaches which scale with . . . . .

The electronic ground state of a periodic system is usually described in terms of extended Bloch orbitals, but an alternative representation in terms of localized "Wannier functions" was introduced by . . . . .

White organic light-emitting diodes (OLEDs) are ultra-thin, large-area light sources made from organic semiconductor materials. Over the last decades, much research has been spent on finding the suita . . . . .
