Quantum criticality and tunable Griffiths phase in superconducting twisted trilayer graphene
Phanibhusan S. Mahapatra, Haining Pan, Kenji Watanabe +3
When dimensionality is reduced, enhanced quantum fluctuations can destroy long-range phase coherence, driving a superconductor insulator transition, SIT, where disorder and electro…
Imaging Self-aligned Moiré Crystals and Quasicrystals in Magic-angle Bilayer Graphene on hBN Heterostructures
Xinyuan Lai, Daniele Guerci, Guohong Li +5
Using scanning-tunneling-microscopy and theoretical modeling on heterostructures of twisted bilayer graphene and hexagonal Boron-Nitride, we show that the emergent super-moire stru…
Emulating moiré materials with quasiperiodic circuit quantum electrodynamics
Tobias Herrig, Christina Koliofoti, Jedediah H. Pixley +2
Topological bandstructures interfering with moiré superstructures give rise to a plethora of emergent phenomena, which are pivotal for correlated insulating and superconducting sta…
Quasiperiodic circuit quantum electrodynamics
Tobias Herrig, Jedediah H. Pixley, Elio J. König +1
Superconducting circuits are an extremely versatile platform to realize quantum information hardware and to emulate topological materials. We here show how a simple arrangement of…
Interaction-induced velocity renormalization in magic angle twisted trilayer graphene
Laura Classen, J. H. Pixley, Elio J. König
Twistronics heterostructures provide a novel route to control the electronic single particle velocity and thereby to engineer strong effective interactions. Here we show that the r…
A moiré superlattice on the surface of a topological insulator
Jennifer Cano, Shiang Fang, J. H. Pixley +1
Twisting van der Waals heterostructures to induce correlated many-body states provides a novel tuning mechanism in solid-state physics. In this work, we theoretically investigate t…
Controlling a quantum point junction on the surface of an antiferromagnetic topological insulator
Nicodemos Varnava, Justin H. Wilson, J. H. Pixley +1
The abstract notion of topology has led to profound insights into real materials. Notably, the surface and edges of topological materials can host physics, such as unidirectional c…
Axial anomaly and longitudinal magnetoresistance of a generic three dimensional metal
Pallab Goswami, J. H. Pixley, S. Das Sarma
We show that the emergence of the axial anomaly is a universal phenomenon for a generic three dimensional metal in the presence of parallel electric () and magnetic () fields…
