Competing impurities and reentrant magnetism in La(2-x)Sr(x)Cu(1-z)Zn(z)O(4) revisited. The role of the Dzyaloshinskii-Moriya and XY anisotropies
L. Adamska, M. B. Silva Neto, C. Morais Smith
We study the order-from-disorder transition and reentrant magnetism in La(2-x)Sr(x)Cu(1-z)Zn(z)O(4) within the framework of a long-wavelength nonlinear sigma model that properly in…
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…
Optical conductivity of charge carriers interacting with a two-level systems reservoir
A. Villares Ferrer, A. O. Caldeira, C. Morais Smith
Using the functional-integral method we investigate the effective dynamics of a charged particle coupled to a set of two-level systems as a function of temperature and external ele…
