Bloch-sphere rotations in driven double-well for ultracold atoms
Michele Modugno, Marco Fattori, Giulio Pettini
We show that, by using suitable protocols for a non-interacting condensate in a driven double-well, one can achieve controlled rotations about arbitrary axes in the equatorial plan…
Hamiltonian Dynamics and Fundamental Phenomena in Biophysics: A Review
Matteo Gori, Roberto Franzosi, Giulio Pettini +1
We review a theoretical and experimental programme addressing two closely related phenomena in biophysics: the classical analogue of Fröhlich phonon condensation in macromolecules…
Topological Phase Diagram of Optimally Shaken Honeycomb Lattices: A Dual Perspective from Stroboscopic and Non-Stroboscopic Floquet Hamiltonians
Álvaro R. Puente-Uriona, Giulio Pettini, Michele Modugno
We present a direct comparison between the stroboscopic and non-stroboscopic effective approaches for ultracold atoms in shaken honeycomb lattices, focusing specifically on the opt…
Topological Theory of Phase Transitions
Matteo Gori, Roberto Franzosi, Giulio Pettini +1
The investigation of the Hamiltonian dynamical counterpart of phase transitions, combined with the Riemannian geometrization of Hamiltonian dynamics, has led to a preliminary formu…
Hamiltonian chaos and differential geometry of configuration space-time
Loris Di Cairano, Matteo Gori, Giulio Pettini +1
This paper tackles Hamiltonian chaos by means of elementary tools of Riemannian geometry. More precisely, a Hamiltonian flow is identified with a geodesic flow on configuration spa…
Geometrical aspects in the analysis of microcanonical phase-transitions
Ghofrane Bel-Hadj-Aissa, Matteo Gori, Vittorio Penna +2
In the present work, we discuss how the functional form of thermodynamic observables can be deduced from the geometric properties of subsets of phase space. The geometric quantitie…
