A critical appraisal of the singularity theorems.
Senovilla JMM. Senovilla JMM. Philos Trans A Math Phys Eng Sci. 2022 May 2;380(2222):20210174. doi: 10.1098/rsta.2021.0174. Epub 2022 Mar 14. Philos Trans A Math Phys Eng Sci. 2022. PMID: 35282689 Review.
The 2020 Nobel prize in Physics has revived the interest in the singularity theorems and, in particular, in the Penrose theorem published in 1965. ...In particular, a discussion of space-time extensions in relation to the theorems is provided. The nature of the singular …

Phase singularity diffusion.
Cheng X, Lockerman Y, Genack AZ. Cheng X, et al. Opt Lett. 2014 Jun 1;39(11):3348-51. doi: 10.1364/OL.39.003348. Opt Lett. 2014. PMID: 24876050
Phase singularities are observed to diffuse with a linear increase of the square displacement R2 with frequency shift. The product of the diffusion coefficient of phase singularities in the transmitted speckle pattern and the photon diffusion coefficient through the …

Engineering phase and polarization singularity sheets.
Lim SWD, Park JS, Meretska ML, Dorrah AH, Capasso F. Lim SWD, et al. Nat Commun. 2021 Jul 7;12(1):4190. doi: 10.1038/s41467-021-24493-y. Nat Commun. 2021. PMID: 34234140 Free PMC article.
Optical phase singularities are zeros of a scalar light field. The most systematically studied class of singular fields is vortices: beams with helical wavefronts and a linear (1D) singularity along the optical axis. Beyond these common and stable 1D topologi …

Unconventional Singularity in Anti-Parity-Time Symmetric Cavity Magnonics.
Yang Y, Wang YP, Rao JW, Gui YS, Yao BM, Lu W, Hu CM. Yang Y, et al. Phys Rev Lett. 2020 Oct 2;125(14):147202. doi: 10.1103/PhysRevLett.125.147202. Phys Rev Lett. 2020. PMID: 33064512
By engineering an anti-parity-time (anti-PT) symmetric cavity magnonics system with precise eigenspace controllability, we observe two different singularities in the same system. One type of singularity, the exceptional point (EP), is produced by tuning the magnon d …

Point singularity array with metasurfaces.
Lim SWD, Park JS, Kazakov D, Spägele CM, Dorrah AH, Meretska ML, Capasso F. Lim SWD, et al. Nat Commun. 2023 Jun 5;14(1):3237. doi: 10.1038/s41467-023-39072-6. Nat Commun. 2023. PMID: 37277345 Free PMC article.
Phase singularities are loci of darkness surrounded by monochromatic light in a scalar field, with applications in optical trapping, super-resolution imaging, and structured light-matter interactions. Although 1D singular structures, like optical vortices, are commo …

Naked singularity, firewall, and Hawking radiation.
Zhang H. Zhang H. Sci Rep. 2017 Jun 21;7(1):4000. doi: 10.1038/s41598-017-03854-y. Sci Rep. 2017. PMID: 28638101 Free PMC article.
Spacetime singularity has always been of interest since the proof of the Penrose-Hawking singularity theorem. ...By using standard quantum theory, we investigate the Hawking radiation emitted from the black holes with naked singularities. Here we show that th …

Singularity analysis of 3-DOF planar parallel continuum robots with constant curvature links.
Lilge S, Wen K, Burgner-Kahrs J. Lilge S, et al. Front Robot AI. 2023 Jan 24;9:1082185. doi: 10.3389/frobt.2022.1082185. eCollection 2022. Front Robot AI. 2023. PMID: 36760825 Free PMC article.
This paper presents the singularity analysis of 3-DOF planar parallel continuum robots (PCR) with three identical legs. ...It is shown that while loci and occurrences of type II singularities are mostly analogous to conventional parallel kinematic mechanisms (PKM), …

Coherence singularity and evolution of partially coherent Bessel-Gaussian vortex beams.
Zhu J, Zhang H, Wang Z, Zhao X, Lu X, Cai Y, Zhao C. Zhu J, et al. Opt Express. 2023 Mar 13;31(6):9308-9318. doi: 10.1364/OE.483647. Opt Express. 2023. PMID: 37157503 Free article.
We theoretically and experimentally confirmed that during free-space propagation, the number of coherence singularities is equal to the magnitude of the TC. In contrast to the Laguerre-Gaussian vortex beam, this quantitative relationship only holds for the case with an off …
