“…The lattice results, however, does not tell how the monopole confines the color. In the preceding papers we have shown how to calculate the effective action of SU(2) QCD, and demonstrated that the stable monopole condensation can take place which generates the mass gap and color confinement in SU(2) QCD [15][16][17]. The purpose of this paper is to generalize this result to the real SU(3) QCD.…”

“…Second,F µν is made of two potentials, the non-topological A µ and topological C µ . This dual structure ofF µν plays an important role in the calculation of the QCD effective action, because this tells that there are actually two candidates of classical magnetic background to choose, the Savvidy background coming from F µν and the monopole background coming from H µν [15][16][17].…”

“…For example, in spontaneous symmetry breaking we have tachyon when we choose the false vacuum. Similarly, in Neveu-Schwarz-Ramond (NSR) arXiv:1811.08303v1 [hep-th] 17 Nov 2018 string theory we have the tachyonic vacuum when we do not make the theory modular invariant and supersymmetric with the Gliozzi-Scherk-Olive (GSO) projection [13,14]. So, obviously there is something wrong in the instability of the SNO vacuum.…”

“…This means that there are actually two possible magnetic backgrounds, the non-topological magnetic background (the Savvidy background) and topological monopole background. Moreover, we can show that only the monopole background is gauge invariant [15][16][17]. So choosing the monopole background in the calculation of the QCD effective action, we can avoid this trouble.…”

“…So the color reflection invariance assures the gauge invariance after the decomposition. This means that, integrating the colored gluons imposing this color reflection invariance under the monopole background we can calculate the QCD effective action gauge invariantly [15][16][17]. This removes the tachyonic modes and allows us to obtain the stable monopole condensation.…”

We show how to calculate the effective potential of SU(3) QCD which tells that the true minimum is given by the monopole condensation. To do this we make the gauge independent Weyl symmetric Abelian decomposition of the SU(3) QCD which decomposes the gluons to the color neutral neurons and the colored chromons. In the perturbative regime this decomposes the Feynman diagram in such a way that the conservation of color is explicit. Moreover, this shows the existence of two gluon jets, the neuron jet and chromon jet, which can be verified by experiment. In the non-perturbative regime, the decomposition puts QCD to the background field formalism and reduces the non-Abelian gauge symmetry to a discrete color reflection symmetry, and provides us an ideal platform to calculate the one-loop effective action of QCD. Integrating out the chromons from the Weyl symmetric Abelian decomposition of QCD gauge invariantly imposing the color reflection invariance, we obtain the SU(3) QCD effective potential which generates the stable monopole condensation and the mass gap. We discuss the physical implications of our result, in particular the possible existence of the vacuum fluctuation mode of the monopole condensation in QCD.

Construction of Sensor for Submicromolar Detection of Riboflavin by Surface Modification of SPCE with Thermal Degradation Products of Nickel Acetate Tetrahydrate

et al. 2022

Nickel acetate tetrahydrate (NAT) sample series were used to modify screen‐printed carbon electrodes (SPCE). The samples were hybrid Ni/NiO nanocomposites, where the NiO phase increased with an applied treatment temperature. Results of electrochemical measurements pointed that the Ni/NiO550/SPCE‐modified electrode had the best analytical performance toward the detection of riboflavin (RF). The Ni/NiO550/SPCE‐based sensor showed linear response with RF in the concentration range of 0.5–75 μM and 0.15 μM LOD in BRBS. Sensor offered fast response time, good repeatability, and selectivity with an RSD of 1.4 %. Our results show that the Ni:NiO nanocomposite ratio strongly influenced the electroanalytical performance of SPCE.

We study the non-relativistic expansion of general relativity coupled to matter. This is done by expanding the metric and matter fields analytically in powers of 1/c 2 where c is the speed of light. In order to perform this expansion it is shown to be very convenient to rewrite general relativity in terms of a timelike vielbein and a spatial metric. This expansion can be performed covariantly and off shell. We study the expansion of the Einstein-Hilbert action up to next-to-next-to-leading order. We couple this to different forms of matter: point particles, perfect fluids, scalar fields (including an off-shell derivation of the Schrödinger-Newton equation) and electrodynamics (both its electric and magnetic limits). We find that the role of matter is crucial in order to understand the properties of the Newton-Cartan geometry that emerges from the expansion of the metric. It turns out to be the matter that decides what type of clock form is allowed, i.e. whether we have absolute time or a global foliation of constant time hypersurfaces. We end by studying a variety of solutions of non-relativistic gravity coupled to perfect fluids. This includes the Schwarzschild geometry, the Tolman-Oppenheimer-Volkoff solution for a fluid star, the FLRW cosmological solutions and anti-de Sitter spacetimes.
