The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

Astronomische Nachrichten, EarlyView.
ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

Compressibility Function and Speed of Sound in the Non‐Commutative Quantum Hadrodynamics Type‐I Model for Neutron Stars

Astronomische Nachrichten, EarlyView.
ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Knowledge acquisition in science and the blurred boundary between perception and cognition

British Educational Research Journal, EarlyView.
Abstract This paper provides a critical and detailed study of what researchers in the fields of contemporary cognition and neuroscience have revealed about the blurred boundary between perception and cognition. We set out the arguments with a view to what researchers and teachers should now consider regarding the subtleties of their interrelationship ...

Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...
