Mechanical characterisation of novel aperiodic lattice structures
Materials & Design, 2023 This paper compares the mechanical properties of a class of lattice metamaterials with aesthetically-pleasing patterns that are governed by the mathematics of aperiodic order.

Aperiodic order and spherical diffraction, I: auto‐correlation of regular model sets [PDF]
, 2016 We study uniform and non‐uniform model sets in arbitrary locally compact second countable (lcsc) groups, which provide a natural generalization of uniform model sets in locally compact abelian groups as defined by Meyer and used as mathematical models of

Broadband Mid-IR superabsorption with aperiodic polaritonic photonic crystals [PDF]
Journal of the European Optical Society-Rapid Publications, 2014 We propose an approach for broadband near-perfect absorption with aperiodic-polaritonic photonic crystals (PCs) operating in the phonon-polariton gap of the constituent material.

Thermal Emission Control via Bandgap Engineering in Aperiodically Designed Nanophotonic Devices
Nanomaterials, 2015 Aperiodic photonic crystals can open up novel routes for more efficient photon management due to increased degrees of freedom in their design along with the unique properties brought about by the long-range aperiodic order as compared to their periodic ...

Aperiodic-Order-Induced Multimode Effects and Their Applications in Optoelectronic Devices
Symmetry, 2019 Unlike periodic and random structures, many aperiodic structures exhibit unique hierarchical natures. Aperiodic photonic micro/nanostructures usually support optical multimodes due to either the rich variety of unit cells or their hierarchical structure.

$m$th-order Fisher-KPP equation with free boundaries and time-aperiodic advection
Mathematics in Applied Sciences and Engineering, 2021 In this paper, we investigate a $m$th-order Fisher-KPP equation with free boundaries and time-aperiodic advection. Considering the influence of advection term and initial conditions on the long time behavior of solutions, we obtain spreading-vanishing ...

Schrödinger’s What is Life?—Complexity, Cognition and the City
Entropy, 2023 This paper draws attention to four central concepts in Schrödinger’s ‘What is Life?’ that have not, as yet, received sufficient attention in the domain of complexity: delayed entropy, free energy, order out of order and aperiodic crystal.

Magneto-Optical Faraday Effect in Quasicrystalline and Aperiodic Microresonator Structures
Magnetochemistry, 2023 We theoretically and numerically investigate magnetophotonic microresonators formed by a magnetic layer sandwiched between two reflective multilayers with different layer arrangements.

Aperiodic Weighted Automata and Weighted First-Order Logic [PDF]
International Symposium on Mathematical Foundations of Computer Science, 2019 By fundamental results of Sch\"utzenberger, McNaughton and Papert from the 1970s, the classes of first-order definable and aperiodic languages coincide. Here, we extend this equivalence to a quantitative setting.
