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.

A strange contribution to the neutron EDM

Journal of High Energy Physics
We analyze the contribution of hypothetical quark electric dipoles to the electric dipole moment (EDM) of the neutron. Particular emphasis is devoted to the strange quark contribution.

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 ...

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

Quark condensates and strange quark matter [PDF]

Physical Review C, 1997
Based upon recent studies on quark condensates, we investigate strange quark matter at zero temperature and find that the mass parametrization popularly used for u/d quarks with the mass-density-dependent model is just a first-order approximation to a more general formula, whereas the corresponding formula for s quarks has to be modified, which leads ...

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.

Phase diagram of dense neutral three-flavor quark matter [PDF]

, 2007
We study the phase diagram of dense, locally neutral three-flavor quark matter as a function of the strange quark mass, the quark chemical potential, and the temperature, employing a general nine-parameter ansatz for the gap matrix.
