Symmetry In The Dissociative Recombination Of Polyatomic Ions
... Finally, we investigate the role of symmetries in few body ultra-cold collisions by considering both three and four identical atoms systems. We derive allowed rearrangements of dierent fragments of the system, satisfying the complete symmetry of the molecular Hamiltonian. For that purpose we establ ...

Real-time evolution for weak interaction quenches in quantum systems
... the same holds for any time average. Hence quantum systems are never ergodic in a classical sense. This limitation does not apply for the expectation value of a particular observable. Nonetheless, the equilibration of expectation values in an integrable system is restricted for a different reason: A ...

Kochen-Specker Theorem and Games
... space of dimension ≥ 8 there is a set of observables for which it is impossible to assign outcomes in a way consistent with quantum mechanics formalism. Proof. The set of observables we are interested in is depicted in Fig. 7. It is easy to check that observables lying on the same edge of the magic ...

Universal formalism of Fano resonance

The key approximation employed is that the self-energy terms and the coupling functions are slow variables, so for energy near an isolated resonance, the Green’s function can be decomposed into a fast and a slowl ...

Modernizing Quantum Annealing using Local Searches
... Abstract. I describe how real quantum annealers may be used to perform local (in state space) searches around specified states, rather than the global searches traditionally implemented in the quantum annealing algorithm. Such protocols will have numerous advantages over simple quantum annealing. By ...
