Interorbital Interactions in an SU(2)xSU(6)-Symmetric Fermi-Fermi Mixture

Benjamin Abeln, Koen Sponselee, Marcel Diem +3

We characterize inter- and intraisotope interorbital interactions between atoms in the 1S0 ground state and the 3P0 metastable state in interacting Fermi-Fermi mixtures of 171Yb an…

Microscopic understanding of ultrafast charge transfer in van-der-Waals heterostructures

R. Krause, S. Aeschlimann, M. Chavez-Cervantes +7

Van-der-Waals heterostructures show many intriguing phenomena including ultrafast charge separation following strong excitonic absorption in the visible spectral range. However, de…

Intermolecular interactions in optical cavities: an ab initio QED study

Tor S. Haugland, Christian Schäfer, Enrico Ronca +2

Intermolecular bonds are weak compared to covalent bonds, but they are strong enough to influence the properties of large molecular systems. In this work, we investigate how strong…

Direct measurement of key exciton properties: energy, dynamics and spatial distribution of the wave function

Shuo Dong, Michele Puppin, Tommaso Pincelli +15

Excitons, Coulomb-bound electron-hole pairs, are the fundamental excitations governing the optoelectronic properties of semiconductors. While optical signatures of excitons have be…

Importance of long-ranged electron-electron interactions for the magnetic phase diagram of twisted bilayer graphene

Lennart Klebl, Zachary A. H. Goodwin, Arash A. Mostofi +2

Electron-electron interactions are intrinsically long ranged, but many models of strongly interacting electrons only take short-ranged interactions into account. Here, we present r…

Engineering Three Dimensional Moiré Flat Bands

Lede Xian, Ammon Fischer, Martin Claassen +3

We demonstrate that the concept of moiré flat bands can be generalized to achieve electronic band engineering in all three spatial dimensions. For many two dimensional van der Waal…
