Current-carrying molecules: a real space picture
Anna Painelli
An approach is presented to calculate characteristic current vs voltage curves for isolated molecules without explicit description of leads. The Hamiltonian for current-carrying mo…
Fractional-filling Mott domains in two dimensional optical superlattices
Pierfrancesco Buonsante, Vittorio Penna, Alessandro Vezzani
Ultracold bosons in optical superlattices are expected to exhibit fractional-filling insulating phases for sufficiently large repulsive interactions. On strictly 1D systems, the ex…
New Directions in Non-Relativistic and Relativistic Rotational and Multipole Kinematics for N-Body and Continuous Systems
D. Alba, L. Lusanna, M. Pauri
In non-relativistic mechanics the center of mass of an isolated system is easily separated out from the relative variables. For a N-body system these latter are usually described b…
General covariance and the objectivity of space-time point-events
L. Lusanna, M. Pauri
"The last remnant of physical objectivity of space-time" is disclosed, beyond the Leibniz equivalence, in the case of a continuous family of spatially non-compact models of general…
Cell strong coupling perturbative approach to the phase diagram of ultracold bosons in optical superlattices
Pierfrancesco Buonsante, Alessandro Vezzani
The phase diagram of ultracold bosons in realistic optical superlattices is addressed via second-order {\it cell} strong coupling perturbative expansions for the Bose-Hubbard model…
A perturbative approach to J mixing in f-electron systems: Application to actinide dioxides
N. Magnani, P. Santini, G. Amoretti +1
We present a perturbative model for crystal-field calculations, which keeps into account the possible mixing of states labelled by different quantum number J. Analytical J-mixing r…
