Capturing Thermal Effects Beyond the Zero‐Temperature Approximation Using the Uniform Electron Gas

Contributions to Plasma Physics, EarlyView.
ABSTRACT Density functional theory at finite temperatures often relies on the zero‐temperature approximation, which uses a ground‐state exchange‐correlation functional with thermalized densities. This approach, however, neglects the explicit temperature dependence of the exchange‐correlation free energy—a key factor in regimes such as warm dense matter,

Catalog of 3 < z < 5.5 Quasar Candidates Selected among XMM-Newton Sources and Its Spectroscopic Verification

Frontiers in Astronomy and Space Sciences, 2017
We have compiled a catalog of 903 quasar candidates (including known quasars) at 3 < z < 5.5 selected among X-ray sources from the XMM-Newton serendipitous survey (3XMM-DR4 catalog).

Vacuum stability and radiative symmetry breaking of the scale-invariant singlet extension of type II seesaw model

European Physical Journal C: Particles and Fields, 2023
The questions of the origin of electroweak symmetry breaking and neutrino mass are two major puzzles in particle physics. Neutrino mass generation requires new physics beyond the Standard Model and also suggests reconsideration of physics of symmetry ...

The X-ray properties and structure of A3571 up to R500

Astronomy & Astrophysics
Abell 3571 is a nearby, X-ray-bright galaxy cluster located in the Shapley Supercluster. Although it appears morphologically relaxed in X-ray images, multiwavelength observations reveal subtle indications of residual dynamical activity likely associated ...

Information theoretic measures for Lifshitz system

Journal of High Energy Physics
In this work, we have studied various mixed state information theoretic quantities for an excited state of Lifshitz spacetime in 3 + 1-dimensions. This geometry is the gravity dual to a class of 2 + 1-dimensional quantum field theories having Lifshitz ...

High-Energy and Ultra-High-Energy Neutrino Astrophysics

Universe
The origin of high-energy cosmic rays, and their behavior in astrophysical sources, remains an open question. Recently, new ways to address this question have been made possible by the observation of a new astrophysical messenger, namely neutrinos.
