Lorentz gauge and Gribov ambiguity in the compact lattice U(1) theory
The Gribov ambiguity problem is studied for compact U(1) lattice theory within the Lorentz gauge. In the Coulomb phase, it is shown that apart from double Dirac sheets all gauge (i.e. Gribov) copies originate mainly from the zero-momentum modes of the gauge fields. The removal of the zero–momentum modes turns out to be necessary for reaching the absolute maximum of the gauge functional F(θ) . A new gauge fixing procedure – zero-momentum Lorentz gauge – is proposed.
More on String Breaking in the 3D Abelian Higgs Model: the Photon Propagator
Abstract We study the Landau gauge photon propagator in the three-dimensional Abelian Higgs model with compact gauge field and fundamentally charged matter in the London limit. The total gauge field is split into singular and regular parts. On the confinement side of the string breaking crossover the momentum dependence of the total propagator is characterized by an anomalous dimension similarly to 3D compact QED. At the crossover and throughout the Higgs region the anomalous dimension disappears. This result perfectly agrees with recent observations that the monopole–antimonopole plasma leads to non-zero anomalous dimension and the presence of the matter fields causes monopole pairing into dipole bound states. The Yukawa mass characterizing the propagator part from regular gauge fields is non-vanishing at the Higgs side and coincides with the mass found for the total propagator. The regular gauge field without anomalous dimension becomes massless at the crossover and in the confinement region.
Concept design of solar cell satellite dish
Solar panels are devices that consist of solar cells that convert light into electricity. They are called solar on the Sun or “sol” because the Sun is the strongest light source that can be utilized. Solar panels are often called photovoltaic cells, photovoltaic can be interpreted as “light-electricity”. Solar cells or PV cells depend on the photovoltaic effect to absorb the Sun’s energy and cause currents to flow between two opposing charged layers. The purpose of this study is to analyze the satellite dish using solar panels, so this tool is a signal search tool that uses solar energy to run to carry out its functions. As we know that many places or areas that are still often experiencing power outages so that it can hamper and interfere with community activities. Therefore, this research wants to facilitate the public, especially the current generation who need electricity every day so that when there is a power outage, the satellite dish will utilize solar energy as its main source. This research uses a satellite dish as an intermediary to produce electrical energy with the help of solar energy and is collected into a high-voltage battery in the form of electricity, so that it becomes a source of electricity.
