Quantum phase transition of infrared radiation

Journal of High Energy Physics
We describe a phase transition of infrared radiation, driven by quantum fluctuations, which takes place at the boundary of (the conformal diagram of) Minkowski spacetime.

Radiative transfer in ultra-relativistic outflows

, 2011
Analytical and numerical solutions are obtained for the equation of radiative transfer in ultra-relativistic opaque jets. The solution describes the initial trapping of radiation, its adiabatic cooling, and the transition to transparency.

Chiral Cherenkov and chiral transition radiation in anisotropic matter [PDF]

, 2018
A significant contribution to the electromagnetic radiation by a fast electric charge moving in anisotropic chiral matter arises from spontaneous photon radiation due to the chiral anomaly.

Transition radiation at radio frequencies from ultrahigh-energy neutrino-induced showers [PDF]

, 2015
Coherent radiation at radio frequencies from high-energy showers fully contained in a dense radio-transparent medium\char22{}like ice, salt, soil, or regolith\char22{}has been extensively investigated as a promising technique to search for ultrahigh ...

Spatial resolution in optical transition radiation beam diagnostics

Physical Review Special Topics. Accelerators and Beams, 1998
An evaluation of the optical transition radiation (OTR) single particle image dimension is obtained using diffraction theory based on a realistic description of the radiation source.

Physics with the ALICE Transition Radiation Detector

, 2011
The ALICE Transition Radiation Detector (TRD) significantly enlarges the scope of physics observables studied in ALICE, because it allows due to its electron identification capability to measure open heavy-flavour production and quarkonium states, which ...

Full-scale ab initio 3D PIC simulations of an all-optical radiation reaction configuration at $10^{21}\mathrm{W/cm^2}$ [PDF]

, 2013
Using full-scale 3D particle-in-cell simulations we show that the radiation reaction dominated regime can be reached in an all optical configuration through the collision of a $\sim$1 GeV laser wakefield accelerated (LWFA) electron bunch with a counter ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

Molecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox
