In this paper, we investigate the growth rates of action for anti--de Sitter black holes in massive-Einstein gravity models and obtain universal behaviors (the holographic complexity) within ``Wheeler-DeWitt'' (WDW) patch at late limit. Furthermore, find that, static neutral cases, when same mass is given, computational speed massive hole as its Einstein counterpart, which independent with effect graviton terms; nevertheless, charged charge parameters are always superior to without terms,...
Based on the infectious disease model with latency, this paper proposes a new for rumor spreading process in online social network. In what we establish an SEIR to describe network varying total number of users and user deactivation rate. We calculate exact equilibrium points reproduction model. Furthermore, perform increasing population size based original real world Facebook The simulation results indicate that changing can accurately reveal inherent characteristics
We examine the evolution of universe in [Formula: see text] gravity where is Ricci curvature and trace energy–momentum tensor. focus on specific form explicitly find out relation between state equation by adiabatic condition. All possible modes scale factor for five kinds equation, are exhibited. simulate numerically plots redshift versus distance modulus three interesting then obtain good fitting curve compared with astronomical observation data.
In this paper we investigate vector particles' Hawking radiation from a Banados–Teitelboim–Zanelli (BTZ) black hole. By applying the Wentzel–Kramers–Brillouin (WKB) approximation and Hamilton–Jacobi ansatz to Proca equation, obtain tunneling spectrum of particles. The expected temperature is recovered.
We study the behavior of entanglement between different degrees freedom scattering fermions, based on an exemplary QED process $e^+e^-\longrightarrow\mu^+\mu^-$. The variation entropy two fermions from initial state to final was computed, with respect ingoing particles. This is found be proportional area quantity, total cross section. also spin-momentum and helicity-momentum entanglements within one particle in aforementioned process. calculations relevant variations mutual information same...
The phase transition and critical behaviours of charged AdS black holes in $f(R)$ gravity with a conformally invariant Maxwell (CIM) source constant curvature are further investigated. As highlight, this research is carried out by employing new state parameters $(T,Q,\Phi)$ contributes to deeper understanding the thermodynamics structure holes. Our analyses manifest that $f(R)$-CIM hole undergoes first order small-large transition, qualitatively behave like Van der Waals liquid-vapor system....
Thermodynamical properties of charged AdS black holes with a global monopole still remain obscure. In this paper, we investigate the thermodynamics and phase transition in extended space. It is shown that thermodynamical quantities exhibit an interesting dependence on internal monopole, they perfectly satisfy both first law Smarr relation. Furthermore, analysis local stability manifests hole undergoes elegant at critical point. Of special interest, behaviors resemble Van der Waals liquid-gas...
We analyze the structure of Faddeev-Jackiw method and show that canonical 2-form Lagrangian constructed in last step is always nondegenerate. So according to Darboux theorem, there must exist a coordinate transformation can transform into standard form. take coordinates after as these phase space, use this form Lagrangian, we achieve its path integral expression over symplectic give quantization integral, then further up concrete application integral.
Starting from the free Polyakov action of an open 2-brane, we obtain solutions to Euler-Lagrange equation. By relating normal modes raising and lowering operators defining vacuum state, achieve spectrum 2-brane at different levels. Interestingly, there are two kinds tachyon states appearing as scalar vector states, respectively. Besides, graviton fields, Kalb-Ramond dilaton, photon appear same level in model.
Vector particles' Hawking radiation as tunneling from the apparent horizon of Vaidya black holes is investigated. By applying WKB approximation and appropriate ansatz for form action to Proca equation, we obtain spectrum vector particles. As a result, expected temperature recovered by particles holes.
