Causality from the spectrum: Emergence of causal order from process-matrix mereology
Varun Kushwaha, Nicolas Loizeau, Alexei Grinbaum +1
In Hamiltonian systems, the only basis-independent quantity is the spectrum. Given a spectrum, quantum mereology seeks preferred tensor-product decompositions into local subsystems…

Krylov space perturbation theory for quantum synchronization in closed systems
Nicolas Loizeau, Berislav Buča
Strongly interacting quantum many-body systems are expected to thermalize, however, some evade thermalization due to symmetries. Quantum synchronization provides one such example o…
