Magnetism in the Dilute Electron Gas of Rhombohedral Multilayer Graphene
Tobias Wolf, Nemin Wei, Haoxin Zhou +1
Lightly-doped rhombohedral multilayer graphene has recently emerged as one of the most promising material platforms for exploring electronic phases driven by strong Coulomb interac…
Gate-tunable topological phases in superlattice modulated bilayer graphene
Yongxin Zeng, Tobias M. R. Wolf, Chunli Huang +4
Superlattice potential modulation can produce flat minibands in Bernal-stacked bilayer graphene. In this work we study how band topology and interaction-induced symmetry-broken pha…
Quasi-boson approximation yields accurate correlation energy in the 2D electron gas
Tobias M. R. Wolf, Chunli Huang
We report the successful adaptation of the quasi-boson approximation, a technique traditionally employed in nuclear physics, to the analysis of the two-dimensional electron gas. We…
Partial condensation of mobile excitons in graphene multilayers
Igor V. Blinov, Chunli Huang, Nemin Wei +3
At a large displacement field, in rhomboedral and Bernal-stacked graphene a normal paramagnetic state transitions to a correlated state. Recent experiments showed that such systems…
Spin and Orbital Metallic Magnetism in Rhombohedral Trilayer Graphene
Chunli Huang, Tobias Wolf, Wei Qin +3
We provide a complete theoretical interpretation of the metallic broken spin/valley symmetry states recently discovered in ABC trilayer graphene (ABC) perturbed by a large transver…
Functional Renormalization Group Study of Superconductivity in Rhombohedral Trilayer Graphene
Wei Qin, Chunli Huang, Tobias Wolf +3
We employ a functional renormalization group approach to ascertain the pairing mechanism and symmetry of the superconducting phase observed in rhombohedral trilayer graphene. Super…
Non-unitary multiorbital superconductivity from competing interactions in Dirac materials
Tobias M. R. Wolf, Maximilian F. Holst, Manfred Sigrist +1
Unconventional superconductors represent one of the most intriguing quantum states of matter. In particular, multiorbital systems have the potential to host exotic non-unitary supe…
Spontaneous Valley Spirals in Magnetically Encapsulated Twisted Bilayer Graphene
Tobias M. R. Wolf, Oded Zilberberg, Gianni Blatter +1
Van der Waals heterostructures provide a rich platform for emergent physics due to their tunable hybridization of electronic orbital- and spin-degrees of freedom. Here, we show tha…
Electrically Tunable Flat Bands and Magnetism in Twisted Bilayer Graphene
T. M. R. Wolf, J. L. Lado, G. Blatter +1
Twisted graphene bilayers provide a versatile platform to engineer metamaterials with novel emergent properties by exploiting the resulting geometric moiré superlattice. Such super…
Tunneling into a finite Luttinger liquid coupled to noisy capacitive leads
Antonio Štrkalj, Michael S. Ferguson, Tobias M. R. Wolf +2
Tunneling spectroscopy of one-dimensional interacting wires can be profoundly sensitive to the boundary conditions of the wire. Here, we analyze the tunneling spectroscopy of a wir…
Substrate-induced topological minibands in graphene
Tobias M. R. Wolf, Oded Zilberberg, Ivan Levkivkskyi +1
The honeycomb lattice sets the basic arena for numerous ideas to implement electronic, photonic, or phononic topological bands in (meta-)materials. Novel opportunities to manipulat…
Unusual band renormalization in the simplest iron based superconductor
J. Maletz, V. B. Zabolotnyy, D. V. Evtushinsky +9
The electronic structure of the iron chalcogenide superconductor FeSe_{1-x} was investigated by high- resolution angle-resolved photoemission spectroscopy (ARPES). The results were…
