Effects of retardation on many-body superradiance in chiral waveguide QED
Bennet Windt, Miguel Bello, Daniel Malz +1
We study the superradiant decay of a chain of atoms coupled to a chiral waveguide, focusing on the regime of non-negligible photon propagation time. Using an exact master equation…

Efficient tensor network simulation of multi-emitter non-Markovian systems
Irene Papaefstathiou, Daniel Malz, J. Ignacio Cirac +1
We present a numerical method to simulate a system of multiple emitters coupled to a non-interacting bath, in any parameter regime. Our method relies on a Block Lanczos transformat…

Computational complexity of isometric tensor network states
Daniel Malz, Rahul Trivedi
We determine the computational power of isometric tensor network states (isoTNS), a variational ansatz originally developed to numerically find and compute properties of gapped gro…
