Quantum Fragmentation
Yiqiu Han, Oliver Hart, Alexey Khudorozhkov +1
We introduce a systematic protocol for constructing quantum Hilbert-space-fragmented Hamiltonians, whose Krylov-sector structure, unlike in classically fragmented models, can be fu…
Exact analytic toolbox for quantum dynamics with tunable noise strength
Mert Okyay, Oliver Hart, Rahul Nandkishore +1
We introduce a framework that allows for the exact analytic treatment of quantum dynamics subject to coherent noise. The noise is modeled via unitary evolution under a Hamiltonian…
Designing open quantum systems with known steady states: Davies generators and beyond
Jinkang Guo, Oliver Hart, Chi-Fang Chen +2
We provide a systematic framework for constructing generic models of nonequilibrium quantum dynamics with a target stationary (mixed) state. Our framework identifies (almost) all c…
