In this paper, we study two-point correlation function in a medium composed of two kinds matter, which is the dual three-dimensional generalized p-brane gas geometry. Following holographic prescription, calculate temporal and spatial functions medium. general, screening effect makes decreases more rapidly than CFTs function. extremal limit, however, find that still conformal.

Abstract We establish the dual equivalence of category generalized (i.e., potentially nonunital) operator systems and pointed compact noncommutative (nc) convex sets, extending a result Davidson 1st author. then apply this to number results about systems, some which are new even in unital setting. For example, we show that maximal minimal C*-covers system can be realized terms theC*-algebra continuous nc functions on its quasistate space, clarifying recent Connes van Suijlekom. also...

Visible matter in the current Universe is a consequence of phase transition strong force, quantum chromodynamics (QCD). This has occurred at temperature around $T_c\simeq 165\,$MeV while it was expanding. Strongly interacting particles are quarks above $T_c$, they pions, protons and neutrons below $T_c$. The spin degrees freedom 37 quark gluon just $T_c$ converted to 3 (pions) after transition. might have been achieved mostly supercooled temperatures. supercooling provided by expansion...

Recently the calculation of holographic free energy for mass-deformed ABJM model (mABJM) with N=2 supersymmetry and SU(3)×U(1) global symmetry was tackled by Bobev et al. [1]. We solve associated BPS equations, requiring IR regularity, using a perturbative method proposed one us in [2]. In particular, we provide an analytic proof crucial conjecture made [1] based on numerical solutions: that R-charge values three chiral multiplets mABJM should be independent hypermultiplet scalar, which is...

For a given entanglement entropy of quantum field theory, we investigate how to reconstruct its dual geometry by applying the Ryu-Takayanagi formula and deep learning method. In holographic setup, radial coordinate is identified with energy scale theory. Therefore, can describe physical properties theory change along renormalization group flow. Intriguingly, show that reconstructed only from data give us more information about other like thermodynamic quantities in infrared region.

Non-commutative graph theory is an operator space generalization of theory. Well known parameters such as the independence number and Lovász theta function were first generalized to this setting by Duan, Severini, Winter. We introduce two new generalizations chromatic non-commutative graphs provide a sandwich inequality. In particular, we show orthogonal complement bounded below its number. also both Sabadussi's Theorem Hedetniemi's conjecture graphs.

We construct a flavor model in an anti-SU(5) grand unified theory with tetrahedral symmetry ${A}_{4}$. choose basis where ${Q}_{\text{em}}=\ensuremath{-}\frac{1}{3}$ quarks and charged leptons are already mass eigenstates. This choice is possible from the ${A}_{4}$ symmetry. Then, matter representation ${\overline{\mathbf{10}}}_{\ensuremath{-}1}^{\text{matter}}$ contains both quark doublet heavy neutrino $N$, which enables us to use ${Q}_{\text{em}}=+\frac{2}{3}$ masses (through see saw via...
