Magnetic mechanism for the biological functioning of hemoglobin
Selma Mayda, Zafer Kandemir, Nejat Bulut +1
The role of magnetism in the biological functioning of hemoglobin has been debated since its discovery by Pauling and Coryell in 1936. The hemoglobin molecule contains four heme gr…
Electronic structure of cyanocobalamin: DFT+QMC study
Selma Mayda, Zafer Kandemir, Nejat Bulut
We study the electronic structure and the magnetic correlations of cyanocobalamin () by using the framework of the multi-orbital single-impurity Haldan…
Electronic structure and correlations of vitamin B12 studied within the Haldane-Anderson impurity model
Zafer Kandemir, Selma Mayda, Nejat Bulut
We study the electronic structure and correlations of vitamin B12 (cyanocobalamine) by using the framework of the multi-orbital single-impurity Haldane-Anderson model of a transiti…
Spin-spin correlations of magnetic impurities in graphene
A. D. Guclu, Nejat Bulut
We study the interaction between two magnetic adatom impurities in graphene using the Anderson model. The two-impurity Anderson Hamiltonian is solved numerically by using the quant…
Quantum Renormalization of the Spin Hall Effect
Bo Gu, Jing-Yu Gan, Nejat Bulut +4
By quantum Monte Carlo simulation of a realistic multiorbital Anderson impurity model, we study the spin-orbit interaction (SOI) of an Fe impurity in Au host metal. We show, for th…
Possible d0 ferromagnetism in MgO doped with nitrogen
Bo Gu, Nejat Bulut, Timothy Ziman +1
We study the possibility of d0 ferromagnetism in the compound MgO doped with nitrogen (N). The Haldane-Anderson impurity model is formulated within the tight-binding approximation…
