Quantitative DFT+DMFT description of spectra and transport in the moderately correlated metal SrVO
Gurshidali P., N. S. Vidhyadhiraja
A quantitative, material-specific account of spectral and transport properties remains a central challenge in the theory of strongly correlated materials. Combining density functio…
Vortex Transport in Ni/Bi Bilayer Superconductor with Strong Spin-Orbit and Exchange Interaction
Laxmipriya Nanda, Sohini Guin, Yasen Hou +7
Nickel/bismuth (Ni/Bi) bilayers are a promising platform for exploring unconventional superconductivity. Ferromagnetic Ni is coupled to Bi, a strong spin orbit metal that only beco…
A typical medium cluster approach for multi-branch phonon localization
Wasim Raja Mondal, Tom Berlijn, N. S. Vidhyadhiraja +1
The phenomenon of Anderson localization in various disordered media has sustained significant interest over many decades. Specifically, the Anderson localization of phonons has bee…
Universal Mott quantum criticality in a modified periodic Anderson model
Sujan K. K., N. S. Vidhyadhiraja
Mott quantum criticality is a central theme in correlated electron physics, observed in systems featuring both continuous zero-temperature transitions and those with finite-tempera…
Interplay of strong correlations and covalency in ionic band insulators
Nagamalleswararao Dasari, Sujan K. K., Juana Moreno +1
We address the role of electronic correlations in different kinds of band insulators by using the two-orbital Hubbard model within the dynamical mean-field theory (DMFT). An intrig…
Mott Criticality as the Confinement Transition of a Pseudogap-Mott Metal
Abhirup Mukherjee, S. R. Hassan, Anamitra Mukherjee +3
The phenomenon of Mott insulation involves the localization of itinerant electrons due to strong local repulsion. Upon doping, a pseudogap (PG) phase emerges - marked by selective…
