Andreev and normal reflections in gapped bilayer graphene-superconductor junctions
Panch Ram, Detlef Beckmann, Romain Danneau +1
We study the Andreev and normal reflection processes -- retro as well as specular -- in a bilayer graphene-superconductor junction where equal and opposite displacement fields are…
Evolution of the Andreev bands in the half-filled superconducting periodic Anderson model
Vladislav Pokorný, Panch Ram
We employ the periodic Anderson model with superconducting correlations in the conduction band at half filling to study the behavior of the in-gap bands in a heterostructure consis…
Inversion and magnetic quantum oscillations in symmetric periodic Anderson model
Panch Ram, Brijesh Kumar
We study the symmetric periodic Anderson model of the conduction electrons hybridized with the localized correlated electrons on square lattice. Using the canonical representation…
Phase diagram of the Hubbard-Kondo lattice model from variational cluster approximation
J. P. L. Faye, M. N. Kiselev, P. Ram +2
The interplay between the Kondo effect and magnetic ordering driven by the Ruderman-Kittel-Kasuya-Yosida interaction is studied within the two-dimensional Hubbard-Kondo lattice mod…
Theory of Quantum Oscillations of Magnetization in Kondo Insulators
Panch Ram, Brijesh Kumar
The Kondo lattice model of spin-1/2 local moments coupled to the conduction electrons at half-filling is studied for its orbital response to magnetic field on bipartite lattices. T…
