Anomalous metal and superconducting phases in rhombohedral graphene
Anna Okounkova, Abigail Sohm, Tobias Faehndrich +7
The paper investigates gate‑tuned regions in rhombohedral graphene on a WSe₂ substrate that show either zero‑resistance superconductivity or a finite‑resistance “anomalous metal” s…
Microwave Imaging of Edge Conductivity in Graphene at Charge Neutrality and Quantum Hall States
Hongtao Yan, Chun-Chih Tseng, Anzhuoer Li +8
We report local conductivity imaging of edge states in monolayer graphene by millikelvin microwave impedance microscopy (MIM). At the charge-neutrality point, as the magnetic field…
Entanglement entropy as a probe of topological phase transitions
Manish Kumar, Bharadwaj Vedula, Suhas Gangadharaiah +1
Entanglement entropy (EE) provides a powerful probe of quantum phases, yet its role in identifying topological phase transitions in disordered systems remains underexplored. We int…
Quantum Spin-1/2 Rings Built from [2]Triangulene Molecular Units
Can Li, Manish Kumar, Ying Wang +14
Quantum spin rings represent fundamental model systems that exhibit distinctive quantum phenomena-such as quantum critical behavior and quasiparticle excitations-arising from their…
Pervasive spin-triplet superconductivity in rhombohedral graphene
Manish Kumar, Derek Waleffe, Anna Okounkova +6
Magnetic fields typically suppress superconductivity once the Zeeman energy exceeds the pairing gap, unless mechanisms such as unconventional pairing, strong spin-orbit coupling, o…
Topological Engineering of a Frustrated Antiferromagnetic Triradical in Aza-Triangulene Architectures
Francisco Romero-Lara, Manuel Vilas-Varela, Ricardo Ortiz +19
Open-shell nanographenes provide a versatile platform to host unconventional magnetic states within their π-conjugated networks. Particularly appealing are graphene architectures t…
