Integrability vs Quantum Thermalization    [PDF]

Jonas Larson

Non-integrability is often taken as a prerequisite for quantum thermalization. Still, a generally accepted definition of quantum integrability is lacking. With the basis in the driven Rabi model we discuss these issues. The only symmetry of the model is the total energy and it would be classified as non-integrable according to the most commonly used definitions. Despite this fact, a thorough analysis conjectures that the system will not thermalize. Thus, our findings suggests: (i) care should be paid when linking non-integrability with thermalization, or (ii) standardly used definitions for quantum integrability are unsatisfactory for certain cases.
