In this paper, we study nucleation of vacuum bubbles in the Brans-Dicke type theory of
gravity. In the Euclidean signatures, we calculate field combinations of vacuum bubbles as
solutions of Einstei...
Peculiar long-range superexchange in Cu2A2O7 (A = P, As, V): a spectacle of anions
Peculiar long-range superexchange spectacle of anions
2010/11/25
A microscopic magnetic model for -Cu2P2O7 is evaluated in a combined theoretical and ex-
perimental study. Despite a dominant intradimer coupling J1, sizable interdimer couplings enforce magnetic or...

Tunable band gaps bilayer graphene-BN heterostructures
2010/11/19
We investigate band-gap tuning of bilayer graphene between hexagonal boron nitride sheets,
by external electric elds. Using density functional theory, we show that the gap is continuously tunable fr...

Solvation Effects in Phase Transitions in Soft Matter
Solvation Effects in Phase Transitions Soft Matter
2010/11/18
Phase transitions in polar binary mixtures can be drastically altered even by a small amount of salt. This is because the preferential solvation strongly depends on the ambient composition.
