Entanglement negativity via replica trick: a Quantum Monte Carlo approach
Chia-Min Chung, Vincenzo Alba, Lars Bonnes +2
Motivated by recent developments in conformal field theory (CFT), we devise a Quantum Monte Carlo (QMC) method to calculate the moments of the partially transposed reduced density…

Bethe ansatz description of edge-localization in the open-boundary XXZ spin chain
Vincenzo Alba, Kush Saha, Masudul Haque
At large values of the anisotropy Δ, the open-boundary Heisenberg spin-1/2 chain has eigenstates displaying localization at the edges. We present a Bethe ansatz description of this…

Entanglement negativity and conformal field theory: a Monte Carlo study
Vincenzo Alba
We investigate the behavior of the moments of the partially transposed reduced density matrix ρ^{T_2}_A in critical quantum spin chains. Given subsystem A as union of two blocks, t…
