Analysis

This paper introduces a novel all-optical lithography platform for creating microstructured surfaces using azopolymers. The key innovation is the use of engineered darkness within computer-generated holograms to control mass transport and directly produce positive, protruding microreliefs. This approach eliminates the need for masks or molds, offering a maskless, fully digital, and scalable method for microfabrication. The ability to control both spatial and temporal aspects of the holographic patterns allows for complex microarchitectures, reconfigurable surfaces, and reprogrammable templates. This work has significant implications for photonics, biointerfaces, and functional coatings.
Reference

The platform exploits engineered darkness within computer-generated holograms to spatially localize inward mass transport and directly produce positive, protruding microreliefs.

Analysis

This paper addresses inconsistencies in previous calculations of extremal and non-extremal three-point functions involving semiclassical probes in the context of holography. It clarifies the roles of wavefunctions and moduli averaging, resolving discrepancies between supergravity and CFT calculations for extremal correlators, particularly those involving giant gravitons. The paper proposes a new ansatz for giant graviton wavefunctions that aligns with large N limits of certain correlators in N=4 SYM.
Reference

The paper clarifies the roles of wavefunctions and averaging over moduli, concluding that holographic computations may be performed with or without averaging.

Analysis

This paper reviews the application of hydrodynamic and holographic approaches to understand the non-equilibrium dynamics of the quark-gluon plasma created in heavy ion collisions. It highlights the challenges of describing these dynamics directly within QCD and the utility of effective theories and holographic models, particularly at strong coupling. The paper focuses on three specific examples: non-equilibrium shear viscosity, sound wave propagation, and the chiral magnetic effect, providing a valuable overview of current research in this area.
Reference

Holographic descriptions allow access to the full non-equilibrium dynamics at strong coupling.

Analysis

This paper explores the connection between the holographic central charge, black hole thermodynamics, and quantum information using the AdS/CFT correspondence. It investigates how the size of the central charge (large vs. small) impacts black hole stability, entropy, and the information loss paradox. The study provides insights into the nature of gravity and the behavior of black holes in different quantum gravity regimes.
Reference

The paper finds that the entanglement entropy of Hawking radiation before the Page time increases with time, with the slope determined by the central charge. After the Page time, the unitarity of black hole evaporation is restored, and the entanglement entropy includes a logarithmic correction related to the central charge.

ArXiv

Analysis

This paper explores non-supersymmetric domain walls in 4D maximal ISO(7) gauged supergravity, a theory derived from massive IIA supergravity. The authors use fake supergravity and the Hamilton-Jacobi formalism to find novel domain walls interpolating between different AdS vacua. The work is relevant for understanding holographic RG flows and calculating quantities like free energy and anomalous dimensions.

Analysis

This paper establishes that the 'chordality condition' is both necessary and sufficient for an entropy vector to be realizable by a holographic simple tree graph model. This is significant because it provides a complete characterization for this type of model, which has implications for understanding entanglement and information theory, and potentially the structure of the stabilizer and quantum entropy cones. The constructive proof and the connection to stabilizer states are also noteworthy.
Reference

The paper proves that the 'chordality condition' is also sufficient.

Analysis

This paper investigates the impact of TsT deformations on a D7-brane probe in a D3-brane background with a magnetic field, exploring chiral symmetry breaking and meson spectra. It identifies a special value of the TsT parameter that restores the perpendicular modes and recovers the magnetic field interpretation, leading to an AdS3 x S5 background. The work connects to D1/D5 systems, RG flows, and defect field theories, offering insights into holographic duality and potentially new avenues for understanding strongly coupled field theories.
Reference

The combined effect of the magnetic field and the TsT deformation singles out the special value k = -1/H. At this point, the perpendicular modes are restored.
