Spin filtering in self-assembled bowl-shaped aromatics Open
Magnetic-conductive AFM reveals that self-assembled bowl-shaped aromatics function as molecular spin filters.

Nanoscale topological defects and improper ferroelectric domains in multiferroic barium hexaferrite nanocrystals Open
Multiferroic materials that demonstrate magnetically driven ferroelectricity have fascinating properties such as magnetic (electric) field-controlled ferroelectric (magnetic) response that can be used in transformative applications includi…

First-principles study of the <i>α</i>-<i>ω</i> phase transformation in Ti and Zr coupled to slip modes Open
We present first-principles density functional theory calculations to study the α-ω phase transformation in Ti and Zr and its coupling to slip modes of the two phases. We first investigate the relative energetics of all possible slip syste…

First-principles study of crystallographic slip modes in ω-Zr Open
We use first-principles density functional theory to study the preferred modes of slip in the high-pressure ω phase of Zr. The generalized stacking fault energy surfaces associated with shearing on nine distinct crystallographic slip modes…

First-principles study of $\langle c+a \rangle$ dislocations in Mg Open
We use first-principles density functional theory to study the generalized stacking fault energy surfaces for pyramidal-I and pyramidal-II slip systems in Mg. We demonstrate that the additional relaxation of atomic motions normal to the sl…

Discovery of superconductivity in pure Bi single crystal Open
Semimetal Bi has been studied extensively for more than a century \cite{1} and still continues to draw enormous scientific interest due to its anomalous electronic properties. In fact, Bi was the first element whose Fermi surface was exper…
