LONG TIME CORRELATIONS OF NONLINEAR LUTTINGER LIQUIDS
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2012)
An overview is given of the limitations of Luttinger liquid theory in describing the real time equilibrium dynamics of critical one-dimensional systems with nonlinear dispersion relation. After exposing the singularities ...
BCS coupling in a 1D Luttinger liquid
(New Journal of Physics, 2015-12-04)
Pareamento BCS em um Líquido de Luttinger em 1D
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2010-12-20)
In this work we investigate the effect of a BCS-type pairing term for free spinless fermions, with a propensity to form a condensate of pairs in a 1+1 dimension. Using the of bosonization technique we explore the possible ...
Pumping current of a Luttinger liquid with finite length
(Springer, 2012-04)
We study transport properties in a Tomonaga-Luttinger liquid in the presence of two timedependent point like weak impurities, taking into account finite-length effects. By employing analytical methods and performing a ...
Friedel oscillations in a Luttinger liquid with long-range interactions
(American Physical Society, 2001-06)
We introduce a path-integral approach that allows us to compute charge-density oscillations in a Luttinger liquid with impurities. We obtain an explicit expression for the envelope of Friedel oscillations in the presence ...
