Orbital splitter effect and spatial resolution of current-induced orbital accumulation

Niels Henrik Aase, Erik Wegner Hodt, Karl Bergson Hallberg +2

The emergence of an orbital angular momentum (OAM) response to a charge current holds promise for technological applications, allowing electrical control of magnetization dynamics.…

Effects of the Hubbard interaction on the quantum metric

Pavlo Sukhachov, Niels Henrik Aase, Kristian Mæland +1

Quantum geometry provides important information about the structure and topology of quantum states in various forms of quantum matter. The information contained therein has profoun…

Orbital currents in lattice multiorbital systems: Continuity equation, torques, and RKKY interaction

Niels Henrik Aase, Erik Wegner Hodt, Jacob Linder +1

Utilizing the electron orbital degree of freedom in heterostructures is attracting increasing attention due to the possibility of achieving much larger conversion rates between cha…

Multiband strong-coupling superconductors with spontaneously broken time-reversal symmetry

Niels Henrik Aase, Kristian Mæland, Asle Sudbø

We study superconducting three-band systems within strong-coupling Eliashberg theory. In particular, we search for phase-frustrated superconducting systems with spontaneous time-re…

Constrained weak-coupling superconductivity in multiband superconductors

Niels Henrik Aase, Christian Svingen Johnsen, Asle Sudbø

We consider superconductivity in a system with Fermi surfaces, including intraband and interband effective electron-electron interactions. The effective interaction is describe…

Dominant superconducting correlations in a Luttinger liquid induced by spin fluctuations

Niels Henrik Aase, Asle Sudbø

We study spin-fluctuation mediated divergent superconducting fluctuations in a Luttinger liquid proximity-coupled to a spin chain. Our study provides insight into how spin fluctuat…

Efficient encoding of the weighted MAX k-CUT on a quantum computer using QAOA

Franz Georg Fuchs, Herman Øie Kolden, Niels Henrik Aase +1

The weighted MAX k-CUT problem consists of finding a k-partition of a given weighted undirected graph G(V,E) such that the sum of the weights of the crossing edges is maximized. Th…
