A Bicontinuous Mesophase Geometry with Hexagonal Symmetry

open access: yesLangmuir, 2011
We report that a specific realization of Schwarz's triply periodic hexagonal minimal surface is isotropic with respect to the Doi-Ohta interface tensor and simultaneously has minimal packing and stretching frustration similar to those of the commonly found cubic bicontinuous mesophases. This hexagonal surface, of symmetry P6(3)/mmc with a lattice ratio

Designer Curved-Space Geometry for Relativistic Fermions in Weyl Metamaterials

open access: yesPhysical Review X, 2017
Weyl semimetals are recently discovered materials supporting emergent relativistic fermions in the vicinity of band-crossing points known as Weyl nodes.

Nonlocal Lagrangian fields and the second Noether theorem. Non-commutative U(1) gauge theory

open access: yesJournal of High Energy Physics
This article focuses on three main contributions. Firstly, we provide an in-depth overview of the nonlocal Lagrangian formalism. Secondly, we introduce an extended version of the second Noether’s theorem tailored for nonlocal Lagrangians.

Symplectic groupoids and Poisson electrodynamics

open access: yesJournal of High Energy Physics
We develop a geometric approach to Poisson electrodynamics, that is, the semi-classical limit of noncommutative U(1) gauge theory. Our framework is based on an integrating symplectic groupoid for the underlying Poisson brackets, which we interpret as the

Optimal geometry for a quartz multipurpose SPM sensor

open access: yesBeilstein Journal of Nanotechnology, 2013
We propose a geometry for a piezoelectric SPM sensor that can be used for combined AFM/LFM/STM. The sensor utilises symmetry to provide a lateral mode without the need to excite torsional modes.
