Polarization angle dependence of the breathing modes in confined one-dimensional dipolar bosons
S. De Palo, E. Orignac, M. L. Chiofalo +1
Probing the radial collective oscillation of a trapped quantum system is an accurate experimental tool to investigate interactions and dimensionality effects. We consider a fully p…
Ballistic transport through quantum point contacts of multi-orbital oxides
J. Settino, C. A. Perroni, F. Romeo +2
Linear and non-linear transport properties through an atomic-size point contact based on oxides two-dimensional electron gas is examined using the tight-binding method and the $\ma…
Roadmap on Atomtronics: State of the art and perspective
L. Amico, M. Boshier, G. Birkl +56
Atomtronics deals with matter-wave circuits of ultra-cold atoms manipulated through magnetic or laser-generated guides with different shapes and intensities. In this way, new types…
Effects of geometric frustration in Kitaev chains
Alfonso Maiellaro, Francesco Romeo, Roberta Citro
We study the topological phase transitions of a Kitaev chain in the presence of geometric frustration caused by the addition of a single long-range hopping. The latter condition de…
Lattice modulation spectroscopy of one-dimensional quantum gases:Universal scaling of the absorbed energy
Roberta Citro, Eugene Demler, Thierry Giamarchi +2
Lattice modulation spectroscopy is a powerful tool for probing low-energy excitations of interacting many-body systems. By means of bosonization we analyze the absorbed power in a…
rf-SQUID measurements of anomalous Josephson effect
Claudio Guarcello, Roberta Citro, Ofelia Durante +6
We discuss the response of an rf-SQUID formed by anomalous Josephson junctions embedded in a superconducting ring with a non-negligible inductance. We demonstrate that a properly s…
