Black Hole Entropy and Superconformal Field Theories on Brane-Antibrane Systems [PDF]
, 2004 We obtain the enropy of Schwarzschild and charged black holes in D>4 from superconformal gases that live on p=10-D dimensional brane-antibrane systems wrapped on T^p.

Subleading eikonal, AdS/CFT and double stress tensors
Journal of High Energy Physics, 2019 The eikonal phase which determines the Regge limit of the gravitational scat- tering amplitude of a light particle off a heavy one in Minkowski spacetimes admits an expansion in the ratio of the Schwarzschild radius of the heavy particle to the impact ...

Black Holes or Objects without Event Horizon?
Reports in Advances of Physical Sciences, 2022 This paper examines the question of whether the generally accepted interpretation of a supermassive object in M87 is the only one possible. There are grounds for this, in particular, due to the detection of a magnetic field in its vicinity.

Surface Tension and Negative Pressure Interior of a Non-Singular `Black Hole'
, 2015 The constant density interior Schwarzschild solution for a static, spherically symmetric collapsed star has a divergent pressure when its radius $R\le\frac{9}{8}R_s=\frac{9}{4}GM$.

Enhancing IR‐MALDESI MSI Spatial Resolution Through Beam Constriction With a Ring‐Actuated Iris
Rapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.ABSTRACT Rationale Infrared matrix‐assisted laser desorption electrospray ionization (IR‐MALDESI) mass spectrometry imaging (MSI) enables label‐free, spatially resolved molecular analysis of biological tissues under ambient conditions. While improving spatial resolution is important for mapping fine tissue structures, mid‐infrared (IR) lasers are ...

Deforming the Double‐Scaled SYK and Reaching the Stretched Horizon From Finite Cutoff Holography
Fortschritte der Physik, Volume 74, Issue 5, May 2026.ABSTRACT We study the properties of the double‐scaled SYK (DSSYK) model under chord Hamiltonian deformations based on finite cutoff holography for general dilaton gravity theories with Dirichlet boundaries. The formalism immediately incorporates a lower‐dimensional analog of TT¯(+Λ2)$\text{T}\overline{\text{T}}(+\Lambda _2)$ deformations, denoted T2 ...
