Visualizing orbital magnetism in electron doped rhombohedral multilayer graphene
Owen I. Sheekey, Trevor B. Arp, Benjamin A. Foutty +24
Electron doped rhombohedral multilayer graphene at high displacement field features an exceptionally flat band minimum with near-ideal quantum geometry. Experiments in this regime…
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…
Topological frequency conversion in rhombohedral multilayer graphene
Étienne Lantagne-Hurtubise, Iliya Esin, Gil Refael +1
We show that rhombohedral multilayer graphene supports topological frequency conversion, whereby a fraction of electrons transfer energy between two monochromatic light sources at…
Josephson diode effects in twisted nodal superconductors
Pavel A. Volkov, Étienne Lantagne-Hurtubise, Tarun Tummuru +3
Recent Josephson tunneling experiments on twisted flakes of high- cuprate superconductor BiSrCaCuO revealed a non-reciprocal behavior of the critical inter…
Quantum geometry and bounds on dissipation in slowly driven quantum systems
Iliya Esin, Étienne Lantagne-Hurtubise, Frederik Nathan +1
We show that energy dissipation in slowly-driven, Markovian quantum systems at low temperature is linked to the geometry of the driving protocol through the quantum (or Fubini-Stud…
Correlated Phases in Spin-Orbit-Coupled Rhombohedral Trilayer Graphene
Jin Ming Koh, Jason Alicea, Étienne Lantagne-Hurtubise
Recent experiments indicate that crystalline graphene multilayers exhibit much of the richness of their twisted counterparts, including cascades of symmetry-broken states and uncon…
Imaging inter-valley coherent order in magic-angle twisted trilayer graphene
Hyunjin Kim, Youngjoon Choi, Étienne Lantagne-Hurtubise +12
Magic-angle twisted trilayer graphene (MATTG) exhibits a range of strongly correlated electronic phases that spontaneously break its underlying symmetries. The microscopic nature o…
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…
Andreev reflection spectroscopy in strongly paired superconductors
Cyprian Lewandowski, Étienne Lantagne-Hurtubise, Alex Thomson +2
Motivated by recent experiments on low-carrier-density superconductors, including twisted multilayer graphene, we study signatures of the BCS to BEC evolution in Andreev reflection…
Spin-Orbit Enhanced Superconductivity in Bernal Bilayer Graphene
Yiran Zhang, Robert Polski, Alex Thomson +7
In the presence of a large perpendicular electric field, Bernal-stacked bilayer graphene (BLG) features several broken-symmetry metallic phases as well as magnetic-field-induced su…
Twisted multilayer nodal superconductors
Tarun Tummuru, Étienne Lantagne-Hurtubise, Marcel Franz
Twisted bilayers of nodal superconductors were recently proposed as a promising platform to host superconducting phases that spontaneously break time-reversal symmetry. Here we ext…
Superconducting instabilities in a spinful Sachdev-Ye-Kitaev model
Étienne Lantagne-Hurtubise, Vedangi Pathak, Sharmistha Sahoo +1
We introduce a spinful variant of the Sachdev-Ye-Kitaev model with an effective time reversal symmetry, which can be solved exactly in the limit of a large number of degrees of…
Traversable wormhole and Hawking-Page transition in coupled complex SYK models

Stephan Plugge, Étienne Lantagne-Hurtubise, Marcel Franz
Quantum effects can stabilize wormhole solutions in general relativity, allowing information and matter to be transported between two connected spacetimes. Here we study the reviva…
Dispersive Landau levels and valley currents in strained graphene nanoribbons
Étienne Lantagne-Hurtubise, Xiao-Xiao Zhang, Marcel Franz
We describe a simple setup generating pure valley currents -- valley transport without charge transport -- in strained graphene nanoribbons with zigzag edges. The crucial ingredien…
Diagnosing quantum chaos in many-body systems using entanglement as a resource
Étienne Lantagne-Hurtubise, Stephan Plugge, Oguzhan Can +1
Classical chaotic systems exhibit exponentially diverging trajectories due to small differences in their initial state. The analogous diagnostic in quantum many-body systems is an…
