Fluctuation Induced Non-Fermi Liquid Behavior near a Quantum Phase Transition in Itinerant Electron Systems
Suresh G. Mishra, P. A. Sreeram
The signature for a non-Fermi liquid behavior near a quantum phase transition has been observed in thermal and transport properties of many metallic systems at low temperatures. In…

Low density ferromagnetism in Extended Hubbard ( t-t'-U ) Model
P. A. Sreeram, Suresh G. Mishra
We study the existence of ferromagnetism in one dimensional Hubbard Model with on site interaction and nearest and next nearest neighbor hopping. Using the Hubbard I approximation,…
