Polaron-Polaritons in Subwavelength Arrays of Trapped Atoms
Kristian Knakkergaard Nielsen, Lukas Wangler, David Castells-Graells +4
Subwavelength arrays of atoms trapped in optical lattices or tweezers are inherently susceptible to deformations: Optomechanical forces displace atoms within their trapping potenti…
Contractivity of time-dependent driven-dissipative systems
Lasse H. Wolff, Daniel Malz, Rahul Trivedi
In a number of physically relevant contexts, a quantum system interacting with a decohering environment is simultaneously subjected to time-dependent controls and its dynamics is t…
Theory of quantum-enhanced interferometry with general Markovian light sources
Erfan Abbasgholinejad, Daniel Malz, Ana Asenjo-Garcia +1
Quantum optical systems comprising quantum emitters interacting with engineered optical modes generate non-classical states of light that can be used as resource states for quantum…
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…
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…
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…
