The singularities of light: intensity, phase, polarisation
Light: Science & Applications, 2023 AbstractIn modern optics, light can be described at different levels: as rays, as scalar waves, as vector fields, and as quantum fields. In the first three levels, there are singularities—characteristic features, useful in interpreting phenomena at that level.

Spacelike Geodesics and Other Puzzles in the Mixmaster Universe [PDF]
, 2012 In this thesis we are going to investigate the behaviour of geodesics in a metric with a singularity known as the ``Mixmaster Universe''. This was motivated from previous work done, where the now well-known AdS/CFT correspondence was used to extract ...

Creation of Bessel–Gaussian Beams from Necklace Beams via Second-Harmonic Generation
PhotonicsThe interest in (quasi-)nondiffracting beams is rooted in applications spanning from secure sharing cryptographic keys real-world free-space optical communications and high-order harmonic generation to high-aspect-ratio nanochannel machining ...

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...

Observation of a phase space horizon with surface gravity water waves
Communications PhysicsIn 1974, Stephen Hawking predicted that quantum effects in the proximity of a black hole lead to the emission of particles and black hole evaporation. At the very heart of this process lies a logarithmic phase singularity which leads to the Bose-Einstein

Phase Characterization of Singular Metasurfaces
ACS PhotonicsThe controlled generation and accurate characterization of light beams carrying orbital angular momentum (OAM) are essential for emerging applications in optical communication, quantum information, and advanced imaging. Metasurfaces offer a versatile platform for tailoring such structured electromagnetic fields.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Can a false vacuum bubble remove the singularity inside a black hole?
European Physical Journal C: Particles and Fields, 2020 We investigate a regular black hole model with a de Sitter-like core at its center. This type of a black hole model with a false vacuum core was introduced with the hope of singularity-resolution and is a common feature shared by many regular black holes.
