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…
A theory of resistivity in Kondo lattice materials: the memory function approach
Komal Kumari, Raman Sharma, Navinder Singh +1
We theoretically analyse D.C. resistivity() in the Kondo-lattice model using the powerful memory function approach. The complete temperature evolution of is investigated usi…
Resistivity of a quantum critical metal
Komal Kumari, Raman Sharma, Navinder Singh +1
We calculate resistivity in the paramagnetic phase just above the curie temperature in a ferromagnetic metal. The required dynamical susceptibility in the formalism of resisti…
Quantum oscillations of the Stoner susceptibility: theory
Ajeet Kumar, Raman Sharma, Navinder Singh +1
Oscillatory effects in magnetic susceptibility of free electrons in a strong magnetic field is well known phenomenon and is well captured by Lifshitz-Kosevich formula. In this pape…
The Memory Function Formalism: A Review
Komal Kumari, Navinder Singh, Navinder Singh Bathinda
An introduction to the Zwanzig-Mori-Götze-Wölfle memory function formalism (or generalized Drude formalism) is presented. This formalism is used extensively in analyzing the experi…
