The Role of Electron Correlations in Chirality Induced Spin Selectivity of Molecular Junctions
A. Konidena, J. Fransson, L. Kantorovich
The Non-Equilibrium Green's Function (NEGF) approach is applied to a chain of Hubbard atoms in a helical geometry sandwiched between two leads, one of which is magnetic, to assess…
Curvature-Controlled Topological Magnon Phases in a Folded Kagome Lattice
Seif Alwan, Jonas Fransson
We show that geometric curvature, encoded in the folding angle between two corner-sharing triangles on a kagome lattice, provides a continuous tuning knob for topological magnon ph…
An argument why the Spinterface model cannot explain the chirality induced spin selectivity effect
J. Fransson
In the context of chirality induced spin selectivity effect, it has been argued that a chiral molecule when adsorbed on a metal facilitates the formation of a local spin moment at…
Should it really be that hard to model the chirality induced spin selectivity effect?
J. Fransson
The chirality induced spin selectivity effect remains a challenge to capture with theoretical modeling. While at least a decade was spent on independent electron models, which comp…
Emergent Topology in Kagome Ferromagnets
Seif Alwan, Jonas Fransson
We investigate the emergence of a topological magnon phase in a two-dimensional kagome ferromagnet with Dzyaloshinskii-Moriya interaction (DMI) and scalar spin chirality. By incorp…
Breaking of Time-Reversal Symmetry and Onsager Reciprocity in Chiral Molecule Interfacd with an Environment
J. Fransson
Molecular closed shell structures are known to form spin-singlet configurations, resulting from the spin-exchange associated with electron-electron interactions. While the vanishin…
Chiral induced Spin Polarized Electron Current: Origin of the Chiral Induced Spin Selectivity Effect
J. Fransson
The discovery of the chiral induced spin selectivity effect has provided a novel tool to study how active physical and chemical mechanism may differ in chiral enantiomers, however,…
Insights into the Mechanism underlying the Chiral-Induced Spin Selectivity: The effect of an Angle-Dependent Magnetic Field and Temperature
Tapan Kumar Das, Ron Naaman, Jonas Fransson
Chiral oligopeptide monolayers were adsorbed on a ferromagnetic surface and their magnetoresistance was measured as a function of the angle between the magnetization of the ferroma…
Electron Paramagnetic Resonance of Single Magnetic Moment on a Surface
P. Berggren, J. Fransson
We address electron spin resonance of single magnetic moments in a tunnel junction using time-dependent electric fields and spin-polarized current. We show that the tunneling curre…
On the non-orthogonality problem in the description of quantum devices
J. Fransson, O. Eriksson, B. Johansson +1
An approach which allows to include the corrections from non-orthogonality of electron states in contacts and quantum dots is developed. Comparison of the energy levels and charge…
