Summary: In this study, higher-dimensional traversable wormholes are investigated within the context of Rindler-AdS/CFT framework. It is shown that the wormhole can be made traversable through a double trace deformation that violates the average null energy condition (ANEC). The research finds a formula for ANEC violation in higher dimensions, and shows that the information transferred through the wormhole propagates with butterfly speed upsilon B=1d-1.

Summary: The study defines defect extremal surface by minimizing the Ryu-Takayanagi surface corrected by the quantum theory localized on the defect, and extends the results to higher dimensions. It is found that the entropy computed from bulk defect extremal surface is generally less than that from island formula in boundary low energy effective theory, suggesting a smaller entropy from the UV completion of island formula.

Summary: By applying recursive renormalization group transformations to a scalar field theory, an effective quantum gravity theory with an emergent extra dimension is obtained. Dynamics of dual order-parameter field and metric tensor field originate from different effective interactions in the Gaussian level approximation. In the large N limit, quantum fluctuations of dynamical metric and dual scalar fields are suppressed, leading to a classical field theory in (D+1)-spacetime dimensions.

Summary: In this study, the entanglement transition in monitored Brownian SYK chains in the large-N limit is investigated. The steady state n-th Renyi entropy is found to saturate to the Page value in the n -> 1 limit without measurement. In the presence of measurements, the analytical continuation n -> 1 is performed using the cyclic symmetric solution. The result shows a continuous von Neumann entanglement entropy transition from volume-law to area-law occurs at the point of replica symmetry unbreaking as the monitoring rate increases.

Summary: The study investigates instabilities in strongly coupled metallic systems using a modified Pomeranchuk technique applied to weakly coupled fermions in a curved AdS bulk. The resulting unstable modes correspond to instabilities in the dual holographic metal. By exploring the phase diagram at zero temperature with varying couplings, the researchers find a wide region where the system is stable and localized around the origin of coupling space.

Summary: The holographic superconductor is a popular model in applied holography. It describes a superfluid phase with a spontaneously broken U(1) global symmetry rather than a superconductor. By using mixed boundary conditions, a genuine holographic superconductor can be constructed, and its near-equilibrium dynamics in the Higgs phase and the characteristic features of the Anderson-Higgs mechanism can be studied. The results show the disappearance of second sound and the emergence of a finite energy gap for the gauge field.

Summary: In this study, we used the cMERA method to approximate the ground state of a T<(T)overbar>-deformed scalar CFT on the line using a Gaussian approximation to the first order deformation parameter. The result was then used to determine the correction to the correlators of scaling operators and the entanglement entropy of a half-line. We found that the T<(T)overbar> deformation induced mild non-localities at short length scales, which did not violate the area law of entanglement. Furthermore, our analysis in the context of the conjectured connection between cMERA and holography suggested the existence of a finite bulk radius in the putative geometric dual description of cMERA, although the entropy analysis contradicted the proposal that no geometry can be ascribed to the region outside this radial cutoff.

Summary: In this study, the condensation of a charged scalar field in a (3 + 1)-dimensional asymptotically AdS background in the context of Einsteinian cubic gravity was investigated. The results revealed that the critical temperature for the superconducting phase transition decreases as the higher curvature coupling increases.

Summary: We study entanglement dynamics in toy models of black hole information and find that the Page curve is related to the transition in the entanglement membrane around the Page time. We also observe rapid transfer of information from the black hole to the radiation around the Page time.

Summary: Pole skipping is a recently discovered subtle effect in the thermal energy density, determined by the stress tensor contribution to many-body chaos. In non-maximally chaotic theories, the true butterfly velocity is uB, and there exists a universal bound u(B) <= uB.

Summary: Existing hydrodynamic models of charged fluids consider external electric fields either as completely arbitrary but first order, or zeroth order but constrained by the fluid's chemical potential. This is contradictory to experimental observations where the electric field is both arbitrary and zeroth order. In this study, we propose a new class of hydrodynamic stationary states that include arbitrary zeroth order electric fields, which allows for the construction of hydrodynamics. By deriving the hydrostatic constitutive relations for a boost-agnostic charged fluid up to first order in derivatives and introducing suitable relaxation terms, we balance the influence of the electric field on the fluid and establish a new hydrostatic constraint on the spatial fluid velocity. This constraint generalizes a similar constraint found in the Drude model of electronic transport and exhibits non-trivial thermo-electric transport with non-linear dependence on the electric field.

Summary: In this study, a holographic framework is used to investigate a strongly interacting fermionic fluid in the presence of an applied magnetic field. The results show that at low temperatures, the translation symmetry is spontaneously broken, leading to a striped Hall fluid phase. The presence of a magnetic field causes the stripes to slide when an electric field is applied parallel to the stripes, a phenomenon known as Hall sliding. The magneto-transport of the system is also examined in the presence of a lattice that breaks the translation symmetry explicitly. The electrical properties are well described by a hydrodynamical model, providing insights into the observed particle-like cyclotron and pseudo-Goldstone excitations. Additionally, a novel semi-circle law is derived analytically for the DC conductivities in the translationally invariant ground state at low temperature.

Summary: The study found that introducing mild nonlocality into otherwise local and chaotic quantum systems can increase the rate of information spreading, but in some cases these rates may be suppressed.

Summary: In Dp-brane holography, entanglement in the target space of the D-brane Yang-Mills theory offers a precise notion of bulk entanglement in the gravity dual. The discussion expands by introducing a gauge invariant characterization of operator sub-algebras corresponding to such entanglement. Additionally, motivation is provided for why these operator sub-algebras are suitable for describing measurements carried out with low-energy probes in the bulk region of interest.

Summary: We study the entanglement entropy of an arbitrary subregion in a system of N non-relativistic fermions in 2+1 dimensions in Lowest Landau Level (LLL) states. Using the connection between these states and an auxiliary 1 + 1 dimensional fermionic system, we derive an expression for the leading large-N contribution in terms of the expectation value of the phase space density operator in 1 + 1 dimensions. Additionally, we obtain analytic expressions for additional contributions from sharp corners on the entangling curve. Our results are important for the integer quantum Hall effect problem and the half-BPS sector of N = 4 Yang Mills theory on S-3, and may have implications for gauge-gravity duality.
