10. Photon Acceleration in Magnetized Plasma: A Potential Source of Fast Radio Bursts

Prof. Sergey Bulanov (ELI-ERIC, ELI BEAMLINES, Za Radnicí 835, Dolní Břežany, 25241, Czech Republic)

15/07/2026, 09:00

Invited talk

We propose a mechanism for fast radio bursts (FRBs) based on photon acceleration by relativistic shocks in highly magnetized electron-positron plasmas, as expected in magnetar magnetospheres. Density modulations at the shock front create relativistically moving refractive index perturbations that transform low-frequency electromagnetic precursors into enhanced high-frequency radiation. In...

25. Nuclear physics and astrophysics driven by intense lasers

Yuanbin Wu (Nankai University)

15/07/2026, 09:35

Invited talk

Owing to the capability of providing extreme conditions such as extremely intense electromagnetic files and high-energy-density environments in the laboratory, high-power laser facilities offer powerful platforms for the studies of various research fields such as particle physics, nuclear physics, and astrophysics. In this talk, we will present and discuss our recent progresses on the studies...

15. Cooling and emission of newborn quark stars

Gregory Vereshchagin (ICRANet)

15/07/2026, 10:10

Invited talk

Cooling of newborn quark stars occurs through neutrino emission from their interiors and photon and electron-positron pairs emission from their surface. We will discuss the cooling process of bare hot quark stars with particular emphasis on luminosity and spectrum, providing input for ongoing observational programs in X-rays.

48. Demonstration of Nonlinear Compton Scattering in the Strongly Nonlinear Regime with Its Implications to High-energy Astrophysics

Chul Min Kim (Center for Relativistic Laser Science, IBS; and Advanced Photonics Research Institute, GIST)

15/07/2026, 11:15

Invited talk

Nonlinear Compton scattering (NCS), the merging of multiple photons into one photon through collision with an energetic electron, is a fundamental process in strong-field quantum electrodynamics (SFQED). The degree of nonlinearity in NCS is quantified by the quantum nonlinearity parameter $\chi$,[1] defined as the electromagnetic field strength observed by the electron in its rest frame...

12. Dark matter effects in compact object dynamics and interior structure

Jorge Armando Rueda Hernandez (ICRANet)

15/07/2026, 11:50

Invited talk

We discuss alternative astrophysical probes of dark matter by estimating its effects on the dynamics and structure of compact objects, such as white dwarfs, neutron stars, and black holes. We analyze gravitational dynamical friction on compact-object binaries, dark-matter accretion, and tidal disruption, and how these effects constrain the nature of the dark-matter particle in observed...

46. Self-Confined Quarks: A General Relativistic Perspective on Strong Nuclear Forces

Prof. Yousef Sobouti (Institute for Advanced Studies in Basic Sciences - Zanjan)

Invited talk

Abstract
Quarks, as spin-$1/2$ particles, can be described as Dirac spinors, and as massive entities, they are capable of curving their surrounding spacetime. We demonstrate that the general relativistic (GR) gravitation of quarks is sufficient to confine them within hadrons while allowing them to remain asymptotically free. Consequently, we conclude that strong nuclear forces and general...
