Predicting the transition temperature, Tc, of a superconductor from Periodic Table normal state properties is regarded as one of the grand challenges of superconductivity. By studying the correlations...
Lifshitz Transition and Quantum Criticality in an Extended Periodic Anderson Model
Lifshitz Transition Quantum Criticality Extended Periodic Anderson Model

We study the quantum phase transition in f-electron systems as a quantum Lifshitz transition
driven by selective Mott localization in a realistic extended Anderson lattice model. Using DMFT,we find t...

We argue that both pocket-disappearing and neck-disrupting types of Lifshitz transitions can be
realized in two-dimensional spin-density wave models for underdoped cuprates, and study both
types of ...

2010/11/22
The research herein studies the Langevin dynamics allowing for an exchange of energy between
liquid crystals and the thermal environment. This dynamics leads to fluctuation and dissipation
behaviors...
