Holographic complexity in the "complexity equals action" approach is reconsidered relaxing requirement of reparameterization invariance action with prescription that vanish any vacuum causal diamond. This implies anti-de Sitter space plays role reference state. Moreover, an Sitter-Schwarzschild black hole becomes intrinsically finite and saturates Lloyd's bound after a critical time. It also ar...

We examine the complexity/volume conjecture and further investigate possible connections between complexity partition function. The 2.0 states that growth rate $\mathcal{\dot{C}}\sim PV$. In standard statistics, there is a fundamental relation among $PV$, grand potential $\Omega$ function $\mathcal{Z}$. By using this relation, we are able to construct an ansatz complexity/partition then utilize...

A bstract We study the canonical purification of pure, bi-partite states (with respect to one parties) obtained by turning on sources in Euclidean path integral. In holographic conformal field theories, Lorentzian bulk dual consists corresponding entanglement wedge glued its CRT image at quantum extremal surface. However, mismatch classical expansions QES due corrections needs be supported a sh...

A bstract We use the replica method to compute entanglement entropy of a universe without gravity entangled in thermofield-double-like state with disjoint gravitating universe. Including wormholes between replicas latter gives an functional which includes “island” on solve back-reaction equations when cosmological constant is negative show that this island coincides causal shadow region created...

A bstract We study how entanglement spreads in the boundary duals of finite-cutoff three-dimensional theories with positive, negative and zero cosmological constant, $$ T\overline{T} T ¯ + Λ 2 two-dimensional theories. first Hawking-Page transition all three cases, fi...

Abstract We propose a gedanken experiment on realizing thermofield double state (TFD) by using analog black holes and provide an approach to test the scrambling time. Through this approach, we demonstrate clearly how shock wave changes TFD as time evolves. As whole system evolves forward in time, perturbation of space-time geometry will increase exponentially. Finally, it destroy entanglement b...

serum albumin is the most aboundant protein in blood plasma. its two major roles aremaintaining osmotic pressure and depositing and transporting compounds. in this paper,albumin-methanol solution simulation is carried out by three techniques including montecarlo (mc), molecular dynamic (md) and langevin dynamic (ld) simulations. byinvestigating energy changes by time and temperature (between 27...

A bstract In this paper, we study the fine structure of entanglement in holographic two-dimensional boundary conformal field theories (BCFT) terms spatially resolved quasilocal extension entropy — contour. We find that induces discontinuities contour revealing hidden localization-delocalization patterns degrees freedom. Moreover, observe formation “islands” where vanishes identically implying t...

We generalize the Gao-Jafferis-Wall construction of traversable two-sided wormholes to multi-boundary wormholes. In our construction, we take background spacetime be black holes in AdS$_3$. work hot limit where dual CFT state certain regions locally resembles thermofield double state. Furthermore, these regions, makes causal shadow exponentially small. Based on two features limit, and with thre...
