Vertex Corrections and the Korringa Ratio in Strongly Correlated Electron Materials
Eddy Yusuf, B. J. Powell, Ross H. McKenzie
We show that the Korringa ratio, associated with nuclear magnetic resonance in metals, is unity if vertex corrections for the dynamic spin susceptibility are negligible and the hyp…
Antiferromagnetic Spin Fluctuations in the Metallic Phase of Quasi-Two-Dimensional Organic Superconductors
Eddy Yusuf, B. J. Powell, Ross H. McKenzie
We give a quantitative analysis of the previously published nuclear magnetic resonance (NMR) experiments in the k-(ET)2X family of organic charge transfer salts by using the phenom…
Dynamics of weakly coupled random antiferromagnetic quantum spin chains
Eddy Yusuf, Kun Yang
We study the low-energy collective excitations and dynamical response functions of weakly coupled random antiferromagnetic spin-1/2 chains. The interchain coupling leads to Neel or…
Spin Waves in Antiferromagnetic Spin Chains with Long Range Interactions
Eddy Yusuf, Anuvrat Joshi, Kun Yang
We study antiferromagnetic spin chains with unfrustrated long-range interactions that decays as a power law with exponent , using the spin wave approximation. We find for suffic…
Random Antiferromagnetic Spin-1/2 Chains with Competing Interactions
Eddy Yusuf, Kun Yang
We study disordered antiferromagnetic spin-1/2 chains with nearest- and further-neighbor interactions using the real-space renormalization-group method. We find that the system sup…
