Non Fermi liquid signatures across strain engineered metal-insulator transition in line-graph lattices

Shashikant Singh Kunwar, Madhuparna Karmakar

Controlling the properties and thus the functionalities of correlated electron systems via externally tunable perturbations has always remained a cherished goal in quantum condense…

Straintronics across Lieb-Kagome interconversion and variable transport scaling exponents

Shashikant Singh Kunwar, Madhuparna Karmakar

We propose a novel protocol of low-temperature, strain-tuned re-entrant metal-insulator transition and crossover between strongly correlated line-graph lattices (Lieb and Kagome).…

Kagome Hubbard model away from the strong coupling limit: Flat band localization and non Fermi liquid signatures

Shashikant Singh Kunwar, Madhuparna Karmakar

Taking cue from the recent experimental realization of metallic phases in Kagome materials we report the low temperature signatures and thermal scales of Kagome metals and insulato…

Tuning a random field mechanism in a frustrated magnet

Shashikant Singh Kunwar, Arnab Sen, Thomas Vojta +1

We study the influence of spinless impurities on a frustrated magnet featuring a spin-density wave (stripe) phase by means of Monte Carlo simulations. We demonstrate that the inter…

Spin-selective metal insulator transition in two dimensions

Shashikant Singh Kunwar, Prabuddha B. Chakraborty, R. Narayanan

The phenomenon of Anderson localization wherein non-interacting electrons are localized by quenched impurities is a subject matter that has been extremely well studied. However, lo…

A distinct bosonic mode in an electron-doped high-transition-temperature superconductor

F. C. Niestemski, S. Kunwar, S. Zhou +5

Despite recent advances in understanding high-transition-temperature (high-T c) superconductors, there is no consensus on the origin of the superconducting 'glue': that is, the med…
