Ferrotoroidic Moment as a Quantum Geometric Phase
C. D. Batista, G. Ortiz, A. A. Aligia
We present a geometric characterization of the ferrotoroidic moment in terms of a set of Abelian Berry phases. We also introduce a fundamental complex quantity which provides an al…

Features of spin-charge separation in the equilibrium conductance through finite rings
Julian Rincon, A. A. Aligia, K. Hallberg
We calculate the conductance through rings with few sites described by the model, threaded by a magnetic flux and weakly coupled to conducting leads at two arbitrary…

Spin-charge separation in strongly interacting finite ladder rings
Julian Rincon, K. Hallberg, A. A. Aligia
We study the conductance through Aharonov-Bohm finite ladder rings with strongly interacting electrons, modelled by the prototypical t-J model. For a wide range of parameters we ob…
