Evolution of C-point singularities and polarization coverage of Poincaré–Bessel beam in self-healing process [PDF]

open access: yesScientific Reports
As a vector version of scalar Bessel beams, Poincaré–Bessel beams (PBBs) have attracted a great deal of attention due to their non-diffracting and self-healing properties as well as the presence of polarization singularities.

Integrable equations associated with the finite‐temperature deformation of the discrete Bessel point process [PDF]

open access: hybridJournal of the London Mathematical Society, 2023
We study the finite‐temperature deformation of the discrete Bessel point process. We show that its largest particle distribution satisfies a reduction of the 2D Toda equation, as well as a discrete version of the integro‐differential Painlevé II equation

Infinite determinantal measures and the ergodic decomposition of infinite Pickrell measures. III. The infinite Bessel process as the limit of the radial parts of finite-dimensional projections of infinite Pickrell measures [PDF]

open access: green, 2016
In the third paper of the series we complete the proof of our main result: a description of the ergodic decomposition of infinite Pickrell measures. We first prove that the scaling limit of the determinantal measures corresponding to the radial parts of ...

Noncolliding Squared Bessel Processes [PDF]

open access: greenJournal of Statistical Physics, 2011
We consider a particle system of the squared Bessel processes with index $ > -1$ conditioned never to collide with each other, in which if $-1 < < 0$ the origin is assumed to be reflecting. When the number of particles is finite, we prove for any fixed initial configuration that this noncolliding diffusion process is determinantal in the ...

Hitting Times of Bessel Processes [PDF]

open access: hybridPotential Analysis, 2012
Let $T_1^{( )}$ be the first hitting time of the point 1 by the Bessel process with index $ \in \R$ starting from $x>1$. Using an integral formula for the density $q_x^{( )}(t)$ of $T_1^{( )}$, obtained in Byczkowski, Ryznar (Studia Math., 173(1):19-38, 2006), we prove sharp estimates of the density of $T_1^{( )}$ which exibit the dependence ...

Bessel-like birth–death process [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2020
We consider models of the population or opinion dynamics which result in the non-linear stochastic differential equations (SDEs) exhibiting the spurious long-range memory. In this context, the correspondence between the description of the birth-death processes as the continuous-time Markov chains and the continuous SDEs is of high importance for the ...

On-chip generation of Bessel–Gaussian beam via concentrically distributed grating arrays for long-range sensing

open access: yesLight: Science and Applications, 2023
Bessel beam featured with self-healing is essential to the optical sensing applications in the obstacle scattering environment. Integrated on-chip generation of the Bessel beam outperforms the conventional structure by small size, robustness, and ...

Strong Approximation of Bessel Processes

open access: greenMethodology and Computing in Applied Probability, 2023
We consider the path approximation of Bessel processes and develop a new and efficient algorithm. This study is based on a recent work by the authors, on the path approximation of the Brownian motion, and on the construction of specific own techniques. It is part of the family of the so-called $\varepsilon$-strong approximations.

Dependence of Monocrystalline Sapphire Dicing on Crystal Orientation Using Picosecond Laser Bessel Beams

open access: yesMicromachines, 2023
Dicing is a critical step in the manufacturing process for the application of sapphire. In this work, the dependence of sapphire dicing on crystal orientation using picosecond Bessel laser beam drilling combined with mechanical cleavage was studied.
