Structural phase transitions in low-dimensional ion crystals
Shmuel Fishman, Gabriele De Chiara, Tommaso Calarco +1
A chain of singly-charged particles, confined by a harmonic potential, exhibits a sudden transition to a zigzag configuration when the radial potential reaches a critical value, de…
The Localization Length of Stationary States in the Nonlinear Schreodinger Equation
Alexander Iomin, Shmuel Fishman
For the nonlinear Schreodinger equation (NLSE), in presence of disorder, exponentially localized stationary states are found. In the present Letter it is demonstrated analytically…
Effects of atomic interactions on Quantum Accelerator Modes
Laura Rebuzzini, Roberto Artuso, Shmuel Fishman +1
We consider the influence of the inclusion of interatomic interactions on the delta-kicked accelerator model. Our analysis concerns in particular quantum accelerator modes, namely…
Fractional -scaling for quantum kicked rotors without cantori
J. Wang, T. S. Monteiro, S. Fishman +2
Previous studies of quantum delta-kicked rotors have found momentum probability distributions with a typical width (localization length ) characterized by fractional -sca…
