Median-point approximation and its application for the study of fermionic systems
Dmytro Makogon, Cristiane Morais Smith
We consider a system of fermions with local interactions on a lattice (Hubbard model) and apply a novel extension of the Laplace's method (saddle-point approximation) for evaluatin…
Bilayer quantum Hall system at : pseudospin models and in-plane magnetic field
O. Tieleman, A. Lazarides, D. Makogon +1
We investigate two theoretical pseudomagnon-based models for a bilayer quantum Hall system (BQHS) at total filling factor . We find a unifying framework which elucidates t…
Effects of Disorder and Interactions in the Quantum Hall Ferromagnet
D. Makogon, A. Alamir, C. Morais Smith
This work treats the effects of disorder and interactions in a quantum Hall ferromagnet, which is realized in a two-dimensional electron gas (2DEG) in a perpendicular magnetic fiel…
Transport properties of a quantum wire: the role of extended time-dependent impurities
D. Makogon, V. Juricic, C. Morais Smith
We study the transport properties of a quantum wire, described by the Tomonaga-Luttinger model, in the presence of a backscattering potential provided by several extended time-depe…
Transport properties of a Luttinger liquid in the presence of several time-dependent impurities
D. Makogon, V. Juricic, C. Morais Smith
We study the transport properties of a Luttinger liquid in the presence of several time-dependent weak point-like impurities. Our starting point is the bosonized form of the Luttin…
