Superconductivity and spin canting in spin-orbit proximitized rhombohedral trilayer graphene
Caitlin L. Patterson, Owen I. Sheekey, Trevor B. Arp +15
Graphene and transition metal dichalcogenide flat-band systems show similar phase diagrams, replete with magnetic and superconducting phases. An abiding question has been whether m…
Symmetry-broken metallic orders in spin-orbit-coupled Bernal bilayer graphene
Jin Ming Koh, Alex Thomson, Jason Alicea +1
We explore Bernal bilayer graphene in the presence of long-range Coulomb interactions, short-range Hund's coupling, and proximity-induced Ising spin-orbit coupling using self-consi…
Gate-Defined Topological Josephson Junctions in Bernal Bilayer Graphene
Ying-Ming Xie, Étienne Lantagne-Hurtubise, Andrea F. Young +2
Recent experiments on Bernal bilayer graphene (BLG) deposited on monolayer WSe revealed robust, ultra-clean superconductivity coexisting with sizable induced spin-orbit couplin…
Vortex-enabled Andreev processes in quantum Hall-superconductor hybrids
Yuchen Tang, Christina Knapp, Jason Alicea
Quantum Hall-superconductor heterostructures provide possible platforms for intrinsically fault-tolerant quantum computing. Motivated by several recent experiments that successfull…
Spectroscopic Signatures of Strong Correlations and Unconventional Superconductivity in Twisted Trilayer Graphene
Hyunjin Kim, Youngjoon Choi, Cyprian Lewandowski +7
Magic-angle twisted trilayer graphene (MATTG) has emerged as a novel moiré material that exhibits both strong electronic correlations and unconventional superconductivity. However,…
Topological superconductivity in nanowires proximate to a diffusive superconductor-magnetic insulator bilayer
Aleksei Khindanov, Jason Alicea, Patrick Lee +2
We study semiconductor nanowires coupled to a bilayer of a disordered superconductor and a magnetic insulator, motivated by recent experiments reporting possible Majorana-zero-mode…
