Abstract We study a thermofield double type entangled state on two disjoint universes A and B, where one of the is asymptotically flat containing black hole. As we increase entanglement temperature, this hole receives back-reaction from stress–energy tensor state. This results in lengthening wormhole region interior, decreasing its horizon area, both which are key features an evaporating then c...

In this work, we perform a holographic study to estimate the effect of backreaction on correlation between two subsystems forming thermofield double (TFD) state. Each these is described as strongly coupled large-Nc thermal field theory, and imparted it sourced by presence uniform distribution heavy static quarks. The TFD state consider here holographically corresponds an entangled AdS blackhole...

A bstract In this paper, we develop a general effective theory for two copies of the Sachdev-Ye-Kitaev (SYK) model with time-dependent bilinear coupling. For quantum quench problem an initial state thermofield double state, show how evolution system is described by complex reparametrization field classical Hamiltonian. We study correlation functions in and compare large- q bulk low energy theor...

Abstract We investigate the thermalization of Sachdev–Ye–Kitaev (SYK) models coupled via random interactions following quenches from perspective entanglement. Previous studies have shown that when a system two SYK by two-body terms is quenched thermofield double state with sufficiently low effective temperature, Rényi entropies do not saturate to expected thermal values in large- N limit. Using...

The emergence of second-harmonic generation (SHG) is a pivotal issue to the development of nano-optical devices and interfaces. Here, we perform a classical analysis of the SHG dynamics with the aim of determining critical values of the electric field. The signals of the SHG process are nonlinear, so it seems reasonable that chaos theory can be a suitable tool to analyze their dynamics. For thi...

We compute the disruption of mutual information between hemispherical subsystems on left and right CFT$s$ a Thermofield Double state described by Kerr geometry in $AdS_4$ due to shockwaves along equatorial plane. The considered respect axi-symmetry geometry. At late times is given lengthening HRT surface connecting two subsystems, we minimum value Lyapunov index-$\lambda_L^{(min)}$ at find that...

We investigate two sparse Sachdev-Ye-Kitaev (SYK) systems coupled by a bilinear term as holographic quantum mechanical description of an eternal traversable wormhole in the low temperature limit. Each SYK system consists $N$ Majorana fermions random $q$-body interactions. The degree sparseness is captured regular hypergraph such way that Hamiltonian contains exactly $k\,N$ independent terms. im...
