Entanglement and relative entropies for low-lying excited states in inhomogeneous one-dimensional quantum systems
Sara Murciano, Paola Ruggiero, Pasquale Calabrese
Conformal field theories in curved backgrounds have been used to describe inhomogeneous one-dimensional systems, such as quantum gases in trapping potentials and non-equilibrium sp…
Unusual area-law violation in random inhomogeneous systems
Vincenzo Alba, Silvia N. Santalla, Paola Ruggiero +3
The discovery of novel entanglement patterns in quantum many-body systems is a prominent research direction in contemporary physics. Here we provide the example of a spin chain wit…
Entanglement entropy of two disjoint intervals and the recursion formula for conformal blocks
Paola Ruggiero, Erik Tonni, Pasquale Calabrese
We reconsider the computation of the entanglement entropy of two disjoint intervals in a (1+1) dimensional conformal field theory by conformal block expansion of the 4-point correl…
