Rotation of intrinsic orbital angular momentum and the orbital Hall effect for twisted particles in arbitrary gravitational fields
For twisted particles in arbitrary gravitational fields, the problems of the rotation of intrinsic orbital angular momentum and the orbital Hall effect are solved in the general case. We need not use the Maxwell equations in curved spacetimes for a description of twisted photons. The exact general equation rigorously defining the OAM dynamics in any Riemannian spacetimes is derived. The general description of different manifestations of the orbital Hall effect for any twisted particles is also …

It’s the moment we’ve feared
—the moment the Supreme Court invoked in giving Donald Trump immunity,
and the moment that marks an authoritarian government at its most vulgar and vicious.
On Monday, Attorney General Pam Bondi signed an order
directing an as-yet-unidentified federal prosecutor to convene a grand jury
to investigate whether prominent officials in Barack Obama’s administration, including Obama himself,
purposely manufactured an intelligence asse…

Bondi’s Obama Grand Jury: The Authoritarian Moment We’ve All Feared
It’s officially happening: the use of the machinery of justice to go on fishing expeditions about political predecessors. Absolute madness.

Pseudorapidity dependence of charged particles production in non-single diffractive $pp$ collisions in the PACIAE 4.0 model
Studying experimental observables is a key benchmark for validating theoretical models in high energy physics. In this work, we employ the PACIAE 4.0 model to simulate non-single diffractive proton-proton ($pp$) collisions at center-of-mass energies of 0.9, 2.36, and 7 TeV, comparing the results with Compact Muon Solenoid (CMS) experimental data on charged-particle pseudorapidity densities and transverse momentum spectra across different pseudorapidity bins, respectively. Our results show good …

On the existence of negative moments for some non-colliding particle systems and its application
We consider a class of $d$-dimensional stochastic differential equations that model a non-colliding random particle system. We provide a sufficient condition, which does not depend on the dimension $d$, for the existence of negative moments of the gap between two particles, and then apply this result to study the strong rate of convergence of the semi-implicit Euler-Maruyama approximation scheme. Our finding improves a recent result of Ngo and Taguchi (Annals of Applied Probability, 2020).

Transient segregation of bi-disperse granular mixtures in a periodic chute flow
Transient size segregation of a bi-disperse granular mixture flowing over a periodic chute is studied using the Discrete Element Method and continuum simulations. A recently developed particle force-based size segregation model is used to predict the time-dependent flow properties of binary mixtures starting from rest. A two-way coupled continuum model that solves the momentum balance and convection-diffusion equations by incorporating the mixture segregation model along with the generalized in…

Had a lot of fun last night, compiling a little playlist of some of my fave old #NinjaTune tracks. So many outstanding artists, tracks, so much variety and also humor (in titles, samples, production)... mementos and signs from a more optimistic era!

Series A, Episode 09 - Project Avalon
GAN: There. [Avalon takes the phial out of the tunic and holds it up, dropping the tunic]
JENNA: [Entering from the corridor] Gan, that's not Avalon. [Avalon drops the phial and it lands on her tunic. She struggles with Jenna and Gan, but is obviously stronger than they are. Blake and Vila arrive and the four of them overpower her.]

Higher-Order Boundary Conditions for Atomistic Dislocation Simulations
We present a higher-order boundary condition for atomistic simulations of dislocations that address the slow convergence of standard supercell methods. The method is based on a multipole expansion of the equilibrium displacement, combining continuum predictor solutions with discrete moment corrections. The continuum predictors are computed by solving a hierarchy of singular elliptic PDEs via a Galerkin spectral method, while moment coefficients are evaluated from force-moment identities with co…

Nonlinear electrodynamic black hole's impact on the gravitational waveforms from periodic orbits
In this paper, we investigate periodic orbits exhibiting zoom-whirl behavior around a magnetically charged black hole (MCBH) within the framework of nonlinear electrodynamics (NED). We examine how the NED charge parameter influences orbital dynamics by modifying the background spacetime geometry, thereby affecting the energy and angular momentum of particles. In particular, we calculate the radii of the marginally bound orbits (MBOs) and innermost stable circular orbits (ISCOs), demonstrating t…
