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…
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…
Single-shot readout in graphene quantum dots
Lisa Maria Gächter, Rebekka Garreis, Chuyao Tong +9
Electrostatically defined quantum dots in bilayer graphene offer a promising platform for spin qubits with presumably long coherence times due to low spin-orbit coupling and low nu…
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…
Kondo effect and spin-orbit coupling in graphene quantum dots
Annika Kurzmann, Yaakov Kleeorin, Chuyao Tong +12
The Kondo effect is a cornerstone in the study of strongly correlated fermions. The coherent exchange coupling of conduction electrons to local magnetic moments gives rise to a Kon…
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,…
Hard superconducting gap in InSb nanowires
Önder Gül, Hao Zhang, Folkert K. de Vries +14
Topological superconductivity is a state of matter that can host Majorana modes, the building blocks of a topological quantum computer. Many experimental platforms predicted to sho…
Quantized conductance and large g-factor anisotropy in InSb quantum point contacts
Fanming Qu, Jasper van Veen, Folkert K. de Vries +10
Due to a strong spin-orbit interaction and a large Landé g-factor, InSb plays an important role in research on Majorana fermions. To further explore novel properties of Majorana fe…
Decoupling edge versus bulk conductance in the trivial regime of an InAs/GaSb double quantum well using Corbino ring geometry
Binh-Minh Nguyen, Andrey A. Kiselev, Ramsey Noah +13
A Corbino ring geometry is utilized to analyze edge and bulk conductance of InAs/GaSb quantum well structures. We show that edge conductance exists in the trivial regime of this th…
