Evidence for Many-Body States in NiPS Revealed by Angle-Resolved Photoelectron Spectroscopy
Miłosz Rybak, Benjamin Pestka, Biplab Bhattacharyya +11
We present -ARPES spectra of the Mott-insulating van der Waals antiferromagnet NiPS. Signatures of strong correlations -- such as the onset of atomic or atomic-ligand multip…
Probing the band structure of the strongly correlated antiferromagnet NiPS3 across its phase transition
Benjamin Pestka, Biplab Bhattacharyya, Milosz Rybak +19
NiPS3 is an exfoliable van-der-Waals intralayer antiferromagnet with zigzag-type spin arrangement. It is distinct from other TMPS3 (TM: transition metal) materials by optical excit…
Robust spin splitting and fermiology in the layered altermagnet CoNb4Se8
Alessandro De Vita, Chiara Bigi, Davide Romanin +44
Altermagnetism defies conventional classifications of collinear magnetic phases, combining compensated magnetization with momentum-dependent, nonrelativistic spin splitting. While…
Orbital Topology of Chiral Crystals for Orbitronics
Kenta Hagiwara, Ying-Jiun Chen, Dongwook Go +15
Chirality is ubiquitous in nature and manifests in a wide range of phenomena including chemical reactions, biological processes, and quantum transport of electrons. In quantum mate…
Identifying band structure changes of FePS3 across the antiferromagnetic phase transition
Benjamin Pestka, Jeff Strasdas, Gustav Bihlmayer +16
Magnetic 2D materials enable novel tuning options of magnetism. As an example, the van der Waals material FePS3, a zigzag-type intralayer antiferromagnet, exhibits very strong magn…
Observation of termination-dependent topological connectivity in a magnetic Weyl kagome-lattice
Federico Mazzola, Stefan Enzner, Philipp Eck +20
Engineering surfaces and interfaces of materials promises great potential in the field of heterostructures and quantum matter designer, with the opportunity of driving new many-bod…
Metalloporphyrins on Oxygen-Passivated Iron: Conformation and Order Beyond the First Layer
David Maximilian Janas, Andreas Windischbacher, Mira Sophie Arndt +15
On-surface metal porphyrins can undergo electronic and conformational changes that play a crucial role in determining the chemical reactivity of the molecular layer. Therefore, und…
Twist angle dependent interlayer transfer of valley polarization from excitons to free charge carriers in WSe/MoSe heterobilayers
Frank Volmer, Manfred Ersfeld, Paulo E. Faria Junior +13
We identify an optical excitation mechanism that transfers a valley polarization from photo-excited electron-hole pairs to free charge carriers in twisted WSe/MoSe heterobi…
Electronic band structure changes across the antiferromagnetic phase transition of exfoliated MnPS probed by -ARPES
Jeff Strasdas, Benjamin Pestka, Milosz Rybak +17
Exfoliated magnetic 2D materials enable versatile tuning of magnetization, e.g., by gating or providing proximity-induced exchange interaction. However, their electronic band struc…
Can the "shadow" of graphene band clarify its flatness?
Matteo Jugovac, Cesare Tresca, Iulia Cojocariu +6
Graphene band renormalization at the proximity of the van Hove singularity (VHS) has been investigated by angle-resolved photoemission spectroscopy (ARPES) on the Li-doped quasi-fr…
Molecular anchoring stabilizes low valence Ni(I)TPP on copper against thermally induced chemical changes
Henning Maximilian Sturmeit, Iulia Cojocariu, Matteo Jugovac +14
Many applications of molecular layers deposited on metal surfaces, ranging from single-atom catalysis to on-surface magnetochemistry and biosensing, rely on the use of thermal cycl…
Evaluation of molecular orbital symmetry via oxygen-induced charge transfer quenching at a metal-organic interface
Iulia Cojocariu, Henning Maximilian Sturmeit, Giovanni Zamborlini +10
Thin molecular films under model conditions are often exploited as benchmarks and case studies to investigate the electronic and structural changes occurring on the surface of meta…
