Beyond a Bag of Features: Set-Level Instability in Sparse Autoencoders
Nikolai Bolik, Lennart Stöpler, Artur Andrzejak
Shani et al. (2026) show that LLM representations broadly recover human category boundaries, while failing to reflect fine-grained typicality structure. Their analysis uses cosine…

Impact of Boundary Conditions on the Double-Kicked Quantum Rotor
Victoria Motsch, Nikolai Bolik, Sandro Wimberger
We study the on-resonance Spin-1/2 Double Kicked Rotor, a periodically driven quantum system that hosts topological phases. Motivated by experimental constraints, we analyze the ef…
