We consider aspects of dynamical baryons in a holographic dual of QCD that is proposed on the basis of a D4/D8-brane configuration. We construct a soliton solution carrying a unit baryon number and show that it is given by an instanton solution of four-dimensional Yang-Mills theory with fixed size. The Chern-Simons term on the flavor D8-branes plays a crucial role of protecting the instanton fr...

We consider the D4−D8−D8 brane system which serves as ultraviolet completion of the Nambu-Jona-Lasinio model, where the only degrees of freedom carrying baryon charge are fermions. By turning on chemical potential for this charge one may expect the formation of the Fermi liquid ground state. At strong coupling we use the dual holographic description to investigate the responses of the system to...

A bstract D2-D8 model admits a numerical solution that corresponds to charge density wave and spin wave. Considering as the background, we numerically solve Dirac equation for probe fermions. From solution, obtain Green’s function study behaviour of spectral density. We begin with generic fermions have studied formation Fermi surface where it develops gap. In addition, incorporated an ionic lat...

We systematically investigated iodine–metal and iodine–iodine bonding in van Koten’s pincer complex 19 modifications changing substituents and/or the transition metal with a PBE0–D3(BJ)/aug–cc–pVTZ/PP(M,I) model chemistry. As novel tool for quantitative assessment of bond strength these complexes we used local mode analysis, originally introduced by Konkoli Cremer, complemented NBO Bader’s QTAI...

The straightforward identification of impurity signals in nuclear magnetic resonance (NMR) spectra is imperative for the structure elucidation and signal assignment synthetic products intermediates. To keep pace with emergence novel green solvents auxiliary compounds (e.g., acids bases), NMR tables databases must be regularly updated. This study reports residual 1H 13C chemical shifts 42 solven...

Bovine respiratory disease is still a major concern and has economic impact. Another consequence of infections the use antimicrobial molecules to control bacterial pathogens. This can participate in emergence shedding resistance that threaten animal as well human health. Appeasing pheromones with their capacity reduce stress thus ability preserve functions immune system have been proposed subst...

We construct dual Type I’ string descriptions to five dimensional supersymmetric fixed points with ENf+1 global symmetry. The background is obtained as the near horizon geometry of the D4-D8 brane system in massive Type IIA supergravity. We use the dual description to deduce some properties of the fixed points.

Abstract We present a class of dynamical solutions for intersecting D4-D8 and D3-D7 brane systems in ten-dimensional type IIA and IIB supergravity. We discuss if these solutions can be recovered in lower-dimensional effective theories for the warped compactification of a general p-brane system. It is found that an effective p + 1-dimensional description is not possible in general due to the ent...
