Hall map and breakdown of Fermi liquid theory in the vicinity of a Mott insulator
Ilia Khait, Sauri Bhattacharyya, Abhisek Samanta +1
The Hall coefficient exhibits anomalous behavior in lightly doped Mott insulators. For strongly interacting electrons its computation has been challenged by analytical and numerica…
Phonon-induced modification of quantum criticality
Abhisek Samanta, Efrat Shimshoni, Daniel Podolsky
We study the effect of acoustic phonons on the quantum phase transition in the O() model. We develop a renormalization group analysis near (3+1) space-time dimensions and derive…
Subgap two-particle spectral weight in disordered -wave superconductors: Insights from mode coupling approach
Prathyush P. Poduval, Abhisek Samanta, Prashant Gupta +2
We study the two-particle spectral functions and collective modes of weakly disordered superconductors using a disordered attractive Hubbard model on square lattice. We show that t…
