Spin pumping and measurement of spin currents in optical superlattices
Christian Schweizer, Michael Lohse, Roberta Citro +1
We report on the experimental implementation of a spin pump with ultracold bosonic atoms in an optical superlattice. In the limit of isolated double wells it represents a 1D dynami…
Stability mechanisms of high current transport in iron-chalcogenides superconducting films
Antonio Leo, Gaia Grimaldi, Pasquale Marra +8
The improvement in the fabrication techniques of iron-based superconductors have made these materials real competitors of high temperature superconductors and MgB. In particula…
Incommensurate phases of a bosonic two-leg ladder under a flux
Edmond Orignac, Roberta Citro, Mario Di Dio +2
A boson two--leg ladder in the presence of a synthetic magnetic flux is investigated by means of bosonization techniques and Density Matrix Renormalization Group (DMRG). We follow…
