Long-Range Effects in Layered Spin Structures
Alessandro Campa, Ramaz Khomeriki, David Mukamel +1
We study theoretically layered spin systems where long-range dipolar interactions play a relevant role. By choosing a specific sample shape, we are able to reduce the complex Hamil…
Driven Macroscopic Quantum Tunneling of Ultracold Atoms in Engineered Optical Lattices
Ramaz Khomeriki, Stefano Ruffo, Sandro Wimberger
Coherent macroscopic tunneling of a Bose-Einstein condensate between two parts of an optical lattice separated by an energy barrier is theoretically investigated. We show that by a…
Coexistence of Josephson oscillations and novel self-trapping regime in optical waveguide arrays
Ramaz Khomeriki, Jerome Leon, Stefano Ruffo
Considering the coherent nonlinear dynamics between two weakly linked optical waveguide arrays, we find the first example of coexistence of Josephson oscillations with a novel self…
