Spectroscopic signatures of many-body correlations in magic angle twisted bilayer graphene
Yonglong Xie, Biao Lian, Berthold Jäck +6
The discovery of superconducting and insulating states in magic angle twisted bilayer graphene (MATBG) has ignited considerable interest in understanding the nature of electronic i…
The light-harvesting complex 2 of allochromatium vinosum: B800 absorption band splitting and exciton relaxation
Xiaomeng Liu, Oliver Kühn
Allochromatium (Alc.) vinosum has a double-peak structure of its absorption band around 800~nm. Previously, the excitonic origin of this feature has been demonstrated experimentall…
Spin-polarized Correlated Insulator and Superconductor in Twisted Double Bilayer Graphene
Xiaomeng Liu, Zeyu Hao, Eslam Khalaf +5
Ferromagnetism and superconductivity typically compete with each other since the internal magnetic field generated in a magnet suppresses the formation of spin-singlet Cooper pairs…
Theory of correlated insulating behaviour and spin-triplet superconductivity in twisted double bilayer graphene
Jong Yeon Lee, Eslam Khalaf, Shang Liu +4
Two monolayers of graphene twisted by a small `magic' angle exhibit nearly flat bands leading to correlated electronic states and superconductivity, whose precise nature including…
A DFT-based Tight-Binding Approach to the Self-consistent Description of Molecule Metal-Nanoparticle Interactions
Xiaomeng Liu, Lennart Seiffert, Thomas Fennel +1
The interaction within a hybrid system consisting of a spherical metal nanoparticle and a nearby organic dye molecule is formulated in a combined quantum-classical approach. Wherea…
