Layer-Controlled Intermolecular Coupling and Many-Body Effects in C Films
Hai-Lan Luo, Weitang Li, Luca Moreschini +4
Crystalline C is a molecular solid whose electronic properties emerge from the interplay of intermolecular hopping, electron correlations, and electron-vibration coupling. U…
Lessons from -RuCl3 for pursuing quantum spin liquid physics in atomically thin materials
Claudia Ojeda-Aristizabal, Xiaohu Zheng, Changsong Xu +20
Quantum spin liquids can arise from Kitaev magnetic interactions, and exhibit fractionalized excitations with the potential for a topological form of quantum computation. This revi…
Modification of the scattering mechanisms in bilayer graphene in proximity to a molecular thin film probed in the mesoscopic regime
Anise Mansour, Deanna Diaz, Movindu Kawshan Dissanayake +19
Quantum coherent effects can be probed in multilayer graphene through electronic transport measurements at low temperatures. In particular, bilayer graphene is known to be suscepti…
New three-dimensional dispersion in the type-II Dirac semimetals PtTe and PdTe revealed through Angle Resolved Photoemission Spectroscopy
Ivan Pelayo, Derek Bergner, Archibald J. Williams +12
PtTe and PdTe are among the first transition metal dichalcogenides that were predicted to host type-II Dirac fermions, exotic particles prohibited in free space. These mate…
Linearly dispersive bands at the onset of correlations in KC films
Ping Ai, Luca Moreschini, Ryo Mori +5
Molecular crystals are a flexible platform to induce novel electronic phases. Due to the weak forces between molecules, intermolecular distances can be varied over relatively large…
