Hofstadter's Butterfly in AdS Black Holes
Kazuki Ikeda, Yaron Oz
We derive the reduced Dirac Hamiltonian on the non-rotating BTZ background and use its redshift structure to construct a gauge-covariant single-band lattice model on the constant-t…

Quantum Information Dynamics of QED in Expanding de Sitter Universe
Kazuki Ikeda, Yaron Oz
We study QED in de Sitter space as a minimal interacting gauge theory in which cosmological expansion directly competes with quantum dynamics. In cosmic time, the hopping redsh…

Geometry Induced Chiral Transport and Entanglement in Background
Kazuki Ikeda, Yaron Oz
We study the real-time chiral dynamics of Dirac fermions in AdS and AdS black hole backgrounds. The spacetime curvature generates a spin connection term, acting as an effec…
