Entanglement and correlations in the continuous multi-scale entanglement renormalization ansatz

Understand

We investigate the entanglement structure of the continuous multi-scale entanglement renormalization ansatz (cMERA) [Haegeman et al., Phys.

• Rev.
• Lett., 110, 100402 (2013)] for ground states of quantum field theories (QFTs).
• The cMERA, proposed as an extension to QFTs of the lattice MERA, is defined directly in the continuum but is nevertheless naturally equipped with a short-distance scale $1/\Lambda$ that acts as a UV regulator for quantum fluctuations.
