Fault-tolerant breathing pattern in optical lattices as a dynamical quantum memory
Zhao-Ming Wang, Lian-Ao Wu, Michele Modugno +3
Proposals for quantum information processing often require the development of new quantum tech- nologies. However, here we build quantum memory by ultracold atoms in one-dimensiona…
One-dimensional s-p superlattice
Wojciech Ganczarek, Michele Modugno, Giulio Pettini +1
The physics of one dimensional optical superlattices with resonant - orbitals is reexamined in the language of appropriate Wannier functions. It is shown that details of the…
Breakdown of the Peierls substitution for the Haldane model with ultracold atoms
Julen Ibañez-Azpiroz, Asier Eiguren, Aitor Bergara +2
We present two independent calculations of the tight-binding parameters for a specific realization of the Haldane model with ultracold atoms. The tunneling coefficients up to next-…
On the effective Dirac equation for ultracold atoms in optical lattices: role of the localization properties of the Wannier functions
Xabier Lopez-Gonzalez, Jacopo Sisti, Giulio Pettini +1
We review the derivation of the effective Dirac equation for ultracold atoms in one-dimensional bichromatic optical lattices, following the proposal by Witthaut et al. Phys. Rev. A…
