A Relativistic Compact Stellar Model of Anisotropic Quark Matter Mixed with Dark Energy

Advances in High Energy Physics, 2021
The possibility of strange stars mixed with dark energy to be one of the candidates for dark energy stars is the main issue of the present study. Our investigation shows that quark matter atcs as dark energy after a certain yet unknown critical condition

Magnetized strange quark matter and magnetized strange quark stars

, 2007
Strange quark matter could be found in the core of neutron stars or forming strange quark stars. As is well known, these astrophysical objects are endowed with strong magnetic fields which affect the microscopic properties of matter and modify the ...

Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

Advanced Physics Research, Volume 4, Issue 7, July 2025.
The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

Recent results from the G0 experiment

EPJ Web of Conferences, 2010
We have measured parity violating asymmetries in elastic electron-proton and quasi-elastic electrondeuteron scattering at backward electron angle. These measurements have been done at two momentum transfers : Q2 = 0.22 and 0.63 (GeV/c)2 .

Inverse moment of the B s -meson distribution amplitude from QCD sum rule

Journal of High Energy Physics, 2020
We derive a QCD sum rule for the inverse moment of the B s -meson light-cone distribution amplitude in HQET. Within this method, the SU(3) f l symmetry violation is traced to the strange quark mass and to the difference between strange and nonstrange ...

Strange-quark asymmetry in the proton in chiral effective theory [PDF]

, 2016
We perform a comprehensive analysis of the strange-antistrange parton distribution function (PDF) asymmetry in the proton in the framework of chiral effective theory, including the full set of lowest order kaon loop diagrams with off-shell and contact ...

Quantum Anomalies in Condensed Matter

Advanced Physics Research, Volume 4, Issue 7, July 2025.
Quantum materials provide a fertile ground in which to test and realize quantum anomalies predicted by quantum field theory. Quantum anomalies need to be canceled globally, however, quantum states with a quantum anomaly can exist at the boundary of topological materials.

Strange matter in compact stars

EPJ Web of Conferences, 2018
We discuss possible scenarios for the existence of strange matter in compact stars. The appearance of hyperons leads to a hyperon puzzle in ab-initio approaches based on effective baryon-baryon potentials but is not a severe problem in relativistic mean ...

Centrality Dependence of Azimuthal Anisotropy of Strange Hadrons in 200 GeV Au+Au Collisions [PDF]

, 2006
Measurements of azimuthal anisotropy for strange and multi-strange hadrons are presented for the first time in their centrality dependence. The high statistics results of v2(pT) allow for a more detailed comparison to hydrodynamical model calculations ...

Oscillation modes of strange quark stars with a strangelet crust [PDF]

, 2017
We study the non-radial oscillation modes of strange quark stars with a homogeneous core and a crust made of strangelets. Using a 2-component equation-of-state model (core+crust) for strange quark stars that can produce stars as heavy as 2 solar masses ...
