Magnetic collective mode in underdoped cuprates: a phenomenological analysis
P. Prelovsek, I. Sega
The dynamical spin susceptibility as relevant for underdoped cuprates is analysed within the memory-function (MeF) approach. A phenomenological damping function combined with a …
Spin fluctuations in cuprates as the key to high
P. Prelovsek, I. Sega, A. Ramsak +1
Spin fluctuations represent the lowest established energy scale in cuprates and are crucial for the understanding of anomalous normal state properties and superconductivity in thes…
Dynamic Spin Structure Factor of SrCu2(BO3)2 at Finite Temperatures
S. El Shawish, J. Bonca, I. Sega
Using finite temperature Lanczos technique on finite clusters we calculate dynamical spin structure factor of the quasi-two-dimensional dimer spin liquid SrCu2(BO3)2 as a function…
Magnetic response of nonmagnetic impurities in cuprates
P. Prelovsek, I. Sega
A theory of the local magnetic response of a nonmagnetic impurity in a doped antiferromagnet, as relevant to the normal state in cuprates, is presented. It is based on the assumpti…
Crossover to non-Fermi-liquid spin dynamics in cuprates
J. Bonca, P. Prelovsek, I. Sega
The antiferromagnetic spin correlation function , the staggered spin susceptibility and the energy scale are studied numerically…
Scaling of the magnetic response in doped antiferromagnets
P. Prelovsek, I. Sega, J. Bonca
A theory of the anomalous scaling of the dynamic magnetic response in cuprates at low doping is presented. It is based on the memory function representation of the dynamical…
