Irreducible many-body correlations in topologically ordered systems

open access: yesNew Journal of Physics, 2016
Topologically ordered systems exhibit large-scale correlation in their ground states, which may be characterized by quantities such as topological entanglement entropy.

Genuine multipartite entanglement in the cluster-Ising model

open access: yesNew Journal of Physics, 2014
We evaluate and analyze the exact value of a measure for local genuine tripartite entanglement in the one-dimensional cluster-Ising model for spin- $\frac{1}{2}$ particles.

Proposal for a loophole-free violation of Bell's inequalities with a set of single photons and homodyne measurements

open access: yesNew Journal of Physics, 2014
We demonstrate that different kinds of mesoscopic quantum states of light can be efficiently generated from a simple iterative scheme. These states exhibit strong non-classical features, and could be of great interest for many applications such as ...

Effects of Lorentz symmetry breaking on quantum coherence in an expanding universe

open access: yesPhysics Letters B
This study investigates the interplay between Lorentz invariance violation (LIV) and quantum decoherence within an expanding universe. Motivated by quantum-gravity phenomenology, we incorporate a minimal length scale via spatial discretization, which ...
