Paraelectric and Ferroelectric States in a Model for Relaxor Ferroelectrics
G. G. Guzmán-Verri, P. B. Littlewood, C. M. Varma
We study the free energy landscape of a minimal model for relaxor ferroelectrics. Using a variational method which includes leading correlations beyond the mean-field approximation…
Structure Factor of a Relaxor Ferroelectric
G. G. Guzmán-Verri, C. M. Varma
We study a minimal model for a relaxor ferroelectric including dipolar interactions, and short-range harmonic and anharmonic forces for the critical modes as in the theory of pure…
Erratum: Effective Lorentz Force due to Small-Angle Impurity Scattering: Magnetotransport in High- Superconductors
C. M. Varma, Elihu Abrahams
The equations in cond-mat/0011020 and Phys. Rev, Lett. 86, 4652 (2001) are valid but a numerical estimate in the paper is incorrect.
Effective Lorentz Force due to Small-angle Impurity Scattering: Magnetotransport in High-Tc Superconductors
C. M. Varma, Elihu Abrahams
We show that a scattering rate which varies with angle around the Fermi surface has the same effect as a periodic Lorentz force on magnetotransport coefficients. This effect, toget…
