Patterned Assembly of Transition Metal Dichalcogenide/Graphene Heterostructures via Direct Laser Writing

open access: yesAdvanced Functional Materials, EarlyView.
The fabrication of patterned transition metal dichalcogenide (TMD)/graphene heterostructures via direct laser writing reveals new interface chemistry and enables efficient, customizable assembly. Selective laser irradiation of functionalized TMD/graphene triggers localized reactions, forming chemically modified interfaces.

Twistor Spaces with Meromorphic Functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1991
Among the class of Kähler surfaces with zero scalar curvature, only the twistor space of those surfaces which are also Ricci-flat can admit nonconstant meromorphic functions. Moreover, the transcendental degree of the function field of the twistor space over such surfaces is equal to one.

Twistorial construction of minimal hypersurfaces

open access: yes, 2014
Every almost Hermitian structure $(g,J)$ on a four-manifold $M$ determines a hypersurface $\Sigma_J$ in the (positive) twistor space of $(M,g)$ consisting of the complex structures anti-commuting with $J$. In this note we find the conditions under which $

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies

open access: yesAdvanced Functional Materials, EarlyView.
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.

On the existence of compact scalar-flat Kähler surfaces [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 1995
A compact compler surface with non-trivial canonical bundle and a Kähler metric ofzero scalar curvature must be a ruled surface. It is also known that not every ruled surface can admit such extremal Kähler metrics.

Conformal higher spin scattering amplitudes from twistor space

open access: yesJournal of High Energy Physics, 2017
We use the formulation of conformal higher spin (CHS) theories in twistor space to study their tree-level scattering amplitudes, finding expressions for all three-point M H V ¯ $$ \overline{\mathrm{MHV}} $$ amplitudes and all MHV amplitudes involving ...
