Understanding the onset of negative electronic compressibility in one- and two-band 2D electron gases: Application to LaAlO/SrTiO
A. D. Mahabir, A. V. Balatsky, J. T. Haraldsen
We investigate the effects of two electronic bands at the negative electronic compressibility (NEC) in a two-dimensional electron gas (2DEG). We use a simple homogeneous model with…
Effects of exchange distortions in the magnetic Kagome lattice
A. A. Coker, A. Saxena, J. T. Haraldsen
This study examines the effect of distorted triangular magnetic interactions in the Kagome lattice. Using a Holstein-Primakoff expansion, we determine the analytical solutions for…
Designing a path towards superconductivity through magnetic exchange in transition-metal intercalated bilayer graphene
Kevin P. Lucht, A. D. Mahabir, A. Alcantara +3
This study examines the potential of superconductivity in transition metal (TM) intercalated bilayer graphene through a systematic study of the electronic and magnetic properties.…
Thermodynamics and spin mapping of quantum excitations in a Heisenberg spin heptamer
A. Roxburgh, J. T. Haraldsen
In this study, we examine the thermodynamics and spin dynamics of spin-1/2 and spin-3/2 heptamers. Through an exact diagonalization of the isotropic Heisenberg Hamiltonian, we find…
Spin channel induced directional dependent spin exchange interactions between divacantly substituted Fe atoms in graphene
R. Putnam, A. V. Balatsky, J. T. Haraldsen
In this study, we investigate the isolated magnetic interactions between two identical Fe atoms divacantly-substituted into graphene. Using density functional theory, we simulated…
First principles investigation of nanopore sequencing using variable voltage bias on graphene-based nanoribbons
Hannah L. McFarland, Towfiq Ahmed, Jian-Xin Zhu +2
In this study, we examine the mechanism of nanopore-based DNA sequencing using a voltage bias across a graphene nanoribbon. Using density functional theory and a non-equilibrium Gr…
