Rigorous free fermion entanglement renormalization from wavelet theory
Jutho Haegeman, Brian Swingle, Michael Walter +3
We construct entanglement renormalization schemes which provably approximate the ground states of non-interacting fermion nearest-neighbor hopping Hamiltonians on the one-dimension…

Entangled wavepackets in the vacuum
Joris Kattemölle, Ben Freivogel
Motivated by the black hole firewall problem, we find highly entangled pairs of spatially localized modes in quantum field theory. We demonstrate that appropriately chosen wavepack…

Some upper and lower bounds on PSD-rank
Troy Lee, Zhaohui Wei, Ronald de Wolf
Positive semidefinite rank (PSD-rank) is a relatively new quantity with applications to combinatorial optimization and communication complexity. We first study several basic proper…
