Quasiparticle and superfluid dynamics in Magic-Angle Graphene
Elías Portolés, Marta Perego, Pavel A. Volkov +12
Magic-Angle Twisted Bilayer Graphene shows a wide range of correlated phases which are electrostatically tunable. Despite a growing knowledge of the material, there is yet no conse…
Gate-defined superconducting channel in magic-angle twisted bilayer graphene
Giulia Zheng, Elías Portolés, Alexandra Mestre-Torá +8
Magic-angle twisted bilayer graphene (MATBG) combines in one single material different phases like insulating, metallic and superconducting. These phases and their in-situ tunabili…
Tunable quantum interferometer for correlated moiré electrons
Shuichi Iwakiri, Alexandra Mestre-Torà, Elías Portolés +8
Magic-angle twisted bilayer graphene (MATBG) can host an intriguing variety of gate-tunable correlated states, including superconducting and correlated insulator states. Junction-b…
Kagomé quantum oscillations in graphene superlattices
Folkert K. de Vries, Sergey Slizovskiy, Petar Tomić +12
Periodic systems feature the Hofstadter butterfly spectrum produced by Brown--Zak minibands of electrons formed when magnetic field flux through the lattice unit cell is commensura…
Gate-defined electron interferometer in bilayer graphene
Shuichi Iwakiri, Folkert K. de Vries, Elías Portolés +5
We present an electron interferometer defined purely by electrostatic gating in encapsulated bilayer graphene. This minimizes possible sample degradation introduced by conventional…
A Tunable Monolithic SQUID in Twisted Bilayer Graphene
Elías Portolés, Shuichi Iwakiri, Giulia Zheng +6
Magic-angle twisted bilayer graphene (MATBG) hosts a number of correlated states of matter that can be tuned by electrostatic doping. Superconductivity has drawn considerable atten…
Quantum capacitive coupling between large-angle twisted graphene layers
Alina Mrenca-Kolasinska, Peter Rickhaus, Giulia Zheng +4
Large-angle twisted bilayer graphene (tBLG) is known to be electronically decoupled due to the spatial separation of the Dirac cones corresponding to individual graphene layers in…
Fabry-Pérot cavities and quantum dot formation at gate-defined interfaces in twisted double bilayer graphene
Elías Portolés, Giulia Zheng, Folkert K. de Vries +8
The rich and electrostatically tunable phase diagram exhibited by moiré materials has made them a suitable platform for hosting single material multi-purpose devices. To engineer s…
Scattering between minivalleys in a moiré material
Petar Tomić, Peter Rickhaus, Aitor Garcia-Ruiz +8
A unique feature of the complex band structures of moiré materials is the presence of minivalleys, their hybridization, and scattering between them. Here we investigate magneto-tra…
Gate-Defined Josephson Junctions in Magic-Angle Twisted Bilayer Graphene
Folkert K. de Vries, Elias Portoles, Giulia Zheng +5
In the past two years, magic-angle twisted bilayer graphene has emerged as a uniquely versatile experimental platform that combines metallic, superconducting, magnetic and insulati…
Correlated electron-hole State in Twisted Double Bilayer Graphene
Peter Rickhaus, Folkert de Vries, Jihang Zhu +9
When twisted to angles near 1°, graphene multilayers provide a new window on electron correlation physics by hosting gate-tuneable strongly-correlated states, including insulators,…
Gap Opening in Twisted Double Bilayer Graphene by Crystal fields
Peter Rickhaus, Giulia Zheng, Jose L. Lado +12
Crystal fields occur due to a potential difference between chemically different atomic species. In Van-der-Waals heterostructures such fields are naturally present perpendicular to…
