Unstable Features, Reproducible Subspaces: Understanding Seed Dependence in Sparse Autoencoders
Gleb Gerasimov, Timofei Rusalev, Nikita Balagansky +3
Sparse autoencoders (SAEs) are widely used to interpret neural network representations, but their utility depends on whether the learned features are reproducible across training r…
Entanglement Entropy in Jackiw-Teitelboim de Sitter gravity with Timelike Boundaries
Timofei Rusalev
The consideration of timelike boundaries in de Sitter static patches has a broad motivation, such as the formulation of a well-defined canonical ensemble and the realization of a n…
Black Holes, Cavities and Blinking Islands
Dmitry S. Ageev, Irina Ya. Aref'eva, Timofei A. Rusalev
Placing a black hole in a cavity provides a natural framework for exploring gravitational scales, thermodynamic instabilities, and effective gravity theories. In this paper, we exa…
Entanglement entropy in de Sitter: no pure states for conformal matter
D. S. Ageev, I. Ya. Aref'eva, A. I. Belokon +2
In this paper, we consider the entanglement entropy of conformal matter for finite and semi-infinite entangling regions, as well as the formation of entanglement islands in four-di…
Infrared Regularization and Finite Size Dynamics of Entanglement Entropy in Schwarzschild Black Hole
D. S. Ageev, I. Ya. Aref'eva, A. I. Belokon +3
In this paper, infrared regularization of semi-infinite entangling regions and island formation for regions of finite size in the eternal Schwarzschild black hole are considered. W…
Entanglement entropy of near-extremal black hole
I. Aref'eva, T. Rusalev, I. Volovich
We study how the entanglement entropy of the Hawking radiation derived using island recipe for the Reissner-Nordström black hole behaves as the black hole mass decreases. A general…
