Quantum many-body spin ratchets

L Zadnik, M Ljubotina, Ž Krajnik, E Ilievski, T Prosen - PRX quantum, 2024 - APS
Introducing a class of SU (2) invariant quantum unitary circuits generating chiral transport,
we examine the role of broken space-reflection and time-reversal symmetries on spin …

Robustness and eventual slow decay of bound states of interacting microwave photons in the Google Quantum AI experiment

FM Surace, O Motrunich - PRX Quantum, 2024 - APS
Integrable models are characterized by the existence of stable excitations that can
propagate indefinitely without decaying. This includes multimagnon bound states in the …

Quantum Zeno Effect in Noisy Integrable Quantum Circuits for Impurity Models

Y Tang, P Kattel, JH Pixley, N Andrei - arxiv preprint arxiv:2408.10304, 2024 - arxiv.org
We theoretically study the open quantum system dynamics (in the Trotterized limit) of
integrable quantum circuits in the presence of onsite dephasing noise with a spin-$\frac …
