Finite temperature pair density wave superconductivity in -wave altermagnets
Amrutha N Madhusuthanan, Madhuparna Karmakar
We demonstrate that altermagnetism provides a field-free mechanism for stabilizing finite-momentum superconductivity in two dimensions. Using a non-perturbative static path approxi…
Thermal stability of pair density wave in a -wave altermagnetic superconductor
Amrutha N Madhusuthanan, Madhuparna Karmakar
We study finite-momentum superconductivity in a two-dimensional -wave altermagnetic superconductor using a non-perturbative Monte Carlo approach beyond mean-field theory. We sho…
Metal-insulator transition and thermal scales in -wave altermagnet
Santhosh Kannan, Jainam Savla, Madhuparna Karmakar
We present the first finite-temperature study of a strongly correlated -wave altermagnet across the Mott insulator-metal transition using a non-perturbative numerical approach.…
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).…
Correlated electrons in flat bands: Concepts and Developments
Madhuparna Karmakar
When the electronic dispersion in a material is independent of momentum, it gives rise to strongly correlated flat bands, with the single particle energy, quenched. Though the noti…
