recommendations! Published in 2020 at "Physical Review A"

DOI: 10.1103/physreva.101.052122

Abstract: In arXiv:2001.03419 we introduce a universal error bound for constrained unitary dynamics within a well-gapped energy band of an isolated quantum system. Here, we provide the full details on the derivation of the bound. In… read more here.

DOI: 10.1103/physrevb.111.l140305

Abstract: We investigate the dynamics of the quantum Ising model on two-dimensional square lattices up to $16 \times 16$ spins. In the ordered phase, the model is predicted to exhibit dynamically constrained dynamics, leading to confinement… read more here.

DOI: 10.1103/physrevlett.129.190601

Abstract: In a recent work [A. Deger et al., Phys. Rev. Lett. 129, 160601 (2022).PRLTAO0031-900710.1103/PhysRevLett.129.160601] we have shown that kinetic constraints can completely arrest many-body chaos in the dynamics of a classical, deterministic, translationally invariant spin… read more here.

DOI: 10.1109/tsipn.2023.3248944

Abstract: A neural architecture to efficiently coordinate the transitions of state variables (states) over a graph is proposed. We consider the coordination of the time evolution of the state variables associated with the nodes on a… read more here.
