Effect of back reaction on entanglement and subregion volume complexity in strongly coupled plasma

Abstract: The back reaction imparted by a uniform distribution of heavy static fundamental quarks on large Nc strongly coupled gauge theory can be holographically realized as a deformation in AdS blackhole background. The presence of back reaction brings significant changes in to the entanglement structure of the strongly coupled boundary theory at finite temperature. Since the deformed blackhole geometry still remains asymptotically AdS, the gauge/ gravity duality allows us to explore the entanglement structure of back reacted plasma in a quantitative way by computing various measures, e.g holographic en­ tanglement entropy (HEE) and entanglement wedge cross section (EWCS). We explicitly study the variation of those entanglement measures with respect to the uniform density of heavy static fundamental quarks present in the boundary theory. In particular, we notice enhancement of both HEE and EWCS with respect to quark density. We also study the effect of back reaction on the holographic subregion volume complexity. In this analysis we observe an occurrence of logarithmic divergence proportional to the quark density parameter.

Experimental Assessment of the Thermo-Hydraulic Performance of Automobile Radiator with Metallic and Nonmetallic Nanofluids

Abstract: The overall heat transfer of a cross flow heat exchanger can be enhanced by using the nanofluids as coolant, which finds application in reducing the size and weight of automobile radiator. However,...

Fluorometric appraisal of HSO4− in aqueous media and daily utilities using organic–inorganic nanohybrids

Abstract: Receptor 1 based on rhodamine dye was designed and characterized using 1H, 13C NMR and mass spectroscopy like spectroscopic techniques. Re-precipitation methods have been used for developing nano-aggregates of 1 (N1) in aqueous medium, which were further used for preparation of inorganic–organic hybrid nanomaterial (H1) i.e. by coating organic nanoparticles with gold nanoparticles. Changes in the photophysical profile by anion binding of N1 and H1 were evaluated using fluorescence spectroscopy. No selectivity was perceived with nano-aggregates (N1) for any anion. However, the hybrid nanomaterial (H1) selectively recognized HSO4− through enhancement of fluorescence emission intensity in aqueous medium. Thus, the hybrid nanomaterial (H1) has been established for sensing of HSO4− and was considered for various parameters like rapid response, good stability in water and is validated for determination of HSO4− ions in daily use items.
