Exact analytic toolbox for quantum dynamics with tunable noise strength
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 …

Nash states versus eigenstates for many-body quantum systems
C Lin, VB Bulchandani, SL Sondhi - arxiv preprint arxiv:2405.21011, 2024 - arxiv.org
Eigenstates of observables such as the Hamiltonian play a central role in quantum
mechanics. Inspired by the pure Nash equilibria that arise in classical game theory, we …
