Entanglement Hamiltonian of the 1+1-dimensional free, compactified boson conformal field theory
Ananda Roy, Frank Pollmann, Hubert Saleur
Entanglement or modular Hamiltonians play a crucial role in the investigation of correlations in quantum field theories. In particular, in 1+1 space-time dimensions, the spectra of…

Critical properties of the Ising model in hyperbolic space
Nikolas P. Breuckmann, Benedikt Placke, Ananda Roy
The Ising model exhibits qualitatively different properties in hyperbolic space in comparison to its flat space counterpart. Due to the negative curvature, a finite fraction of the…
