**Title**Interacting cMERA: variational wavefunctional for strongly correlated QFTs

**Abstract**The continuous multiscale entanglement renormalization ansatz (cMERA) was proposed in 2011 by Haegeman et al. as a variational wavefunctional for quantum fields. However, so far cMERA is only well understood for non-interacting QFTs or within perturbation theory. In this talk we explain how to numerically generate and manipulate strongly correlated cMERA wavefunctionals for interacting QFTs in the non-perturbative regime. We efficiently produce scale-invariant wavefunctionals in one spatial dimension that are (i) highly non-gaussian and display (ii) power-law decay of correlations and (iii) logarithmic scaling of entanglement entropy. We discuss the potential application of this ansatz to solving scale-invariant quantum field theories variationally.
