Effective Hamiltonians, prethermalization, and slow energy absorption in periodically driven many-body systems

In this paper, we show that the non equilibrium dynamics following a single local quench out of the ground state is suf- ficient to unveil the excitation spectrum of a

Nous avons aussi organisé une collaboration de recherche avec une thèse CIFRE pour modéliser plus finement le comportement thermique et thermodynamique du GNL et

The basic idea is to parametrize these interactions either by zero-range forces like the force of Skyrme or by short finite-range forces like the Gogny interaction in order to

The discussion of seniority in atoms and in nuclei differs in two aspects: (i) LS coupling is a good first-order approximation in atoms while in nuclei it is rather jj coupling and

In conclusion, we have introduced the vdW-MB model, which accurately captures the long-range many-body vdW energy in large molecular systems, to illustrate both the limitations of

Probability density for the center of mass of the soliton at time t = 4000, numerically computed using the many-body quasi-exact dynamics (solid line, averaged over 96

Based on this perturbative method, we have obtained general formulas and identified diverse driving schemes leading to “ non- trivial ” effective Hamiltonians, whose

We decided to change the title because the differences between the two versions are rather important: the preliminaries concerning the theory of Hilbert C ∗ -modules and the role of
