Non-Drude behaviour of optical conductivity in Kondo-lattice systems
Komal Kumari
The optical conductivity in a Kondo lattice system is presented in terms of the memory function formalism. I use Kondo-lattice Hamiltonian for explicit calculations. I compute the…

Density-Driven Resistance Response in : Theory
Komal Kumari, Raman Sharma, Navinder Singh +1
A colossal insulator-to-metal transition in high-spin pyrite phase of has been experimentally observed \cite{colomns2}. There are two possibilities behind this colossal i…

Electrical resistivity in 2d Kondo lattice systems
Komal Kumari
I extend the calculations represented in \cite{konav} regarding the resistivity in Kondo lattice materials from syatem to systems. In the present work I consider a 2d sys…
