Majorana signatures in an asymmetrically coupled quantum dot--topological superconducting nanowire junction
Levente Máthé, Ioan Grosu, Liviu P. Zârbo +1
We present a theoretical study of the quantum transport through a nanoscale system in which a central quantum dot (QD) is coupled asymmetrically to normal leads and to two Majorana…

Friedel oscillations in a two-dimensional electron gas and monolayer graphene with a non-Coulomb impurity potential
Levente Máthé, Ioan Grosu
We study Friedel oscillations in a two-dimensional non-interacting electron gas and in a monolayer graphene in the presence of a single impurity. The potential generated by the imp…

Hartree-Fock approximation for non-Coulomb interactions in three and two-dimensional systems
Vlad-Mihai Ene, Ilinca Lianu, Ioan Grosu
We analyzed the Hartree-Fock approximation for an electron system. The interaction between particles is modeled by a non-Coulombian potential. We analyzed both the three-dimensiona…
