NP Stokes fields for radio astronomy

open access: yes, 2010
The spin weighted spherical harmonic (SWSH) description of angular functions typically is associated with the Newman-Penrose (NP) null tetrad formalism.

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

open access: yesAdvanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Enhanced Trapping with an Optimized Graphene‐Based Bowtie Plasmonic Nanotweezer: Design, Analysis, and Bioanalytical Applications

open access: yesAdvanced Photonics Research, EarlyView.
A graphene‐based bowtie plasmonic nanotweezer is designed and optimized using particle swarm optimization and transfer matrix analysis. The structure achieves strong field confinement, delivering trapping forces up to 6 nN W−1 for 10 nm bioparticles with sixfold lower power requirements than conventional designs.

Entanglement decoherence in a gravitational well according to the event formalism

open access: yes, 2014
The event formalism is a non-linear extension of quantum field theory designed to be compatible with the closed time-like curves that appear in general relativity. Whilst reducing to standard quantum field theory in flat space-time the formalism leads to

Comparison of the Performance of Fluorescent, Phosphorescent, and TADF Luminophores for Explosives Sensing

open access: yesAdvanced Sensor Research, EarlyView.
Both singlet and triplet populations of the TADF compound 4CzIPN are quenched upon interaction with dinitrotoluene by photoinduced electron transfer. However, their quenching rate is different, with the triplet excitons being more efficiently quenched due to a combination of their longer lifetime and larger population.

In Defence of 'Structural Listening': Some Problems With the New Musicology

open access: yesMuzikološki Zbornik, 2005
This essay raises a number of issues with regard to recent developments in music theory. Among them is the turn against 'analysis' or 'structural listening' on account of their (supposed) investment in a discourse of mainstream musicology whose aim is to
