Competing Orbital Magnetism and Superconductivity in electrostatically defined Josephson Junctions of Alternating Twisted Trilayer Graphene
Vishal Bhardwaj, Lekshmi Rajagopal, Lorenzo Arici +8
The coexistence of superconductivity and magnetism within a single material system represents a long-standing goal in condensed matter physics. Van der Waals-based moiré superlatti…
Quantum Geometric Kohn-Luttinger Superconductivity
Gal Shavit, Jason Alicea
Coulomb repulsion can, counterintuitively, mediate Cooper pairing via the Kohn-Luttinger mechanism. However, it is commonly believed that observability of the effect requires speci…
Designing (higher) Hall crystals
Nisarga Paul, Gal Shavit, Liang Fu
We introduce a novel platform for realizing interaction-induced Hall crystals with diverse Chern numbers . This platform consists of a two-dimensional semiconductor or graphene…
Entropy-Enhanced Fractional Quantum Anomalous Hall Effect
Gal Shavit
Strongly interacting electrons in a topologically non trivial band may form exotic phases of matter. An especially intriguing example of which is the fractional quantum anomalous H…
Ephemeral Superconductivity Atop the False Vacuum
Gal Shavit, Stevan Nadj-Perge, Gil Refael
A many body system in the vicinity of a first-order phase transition may get trapped in a local minimum of the free energy landscape. These so-called false-vacuum states may surviv…
Twist-Programmable Superconductivity in Spin-Orbit Coupled Bilayer Graphene
Yiran Zhang, Gal Shavit, Huiyang Ma +8
The relative twist angle between layers of near-lattice-matched van der Waals materials is critical for the emergent correlated phenomena associated with moire flat bands. However,…
Imaging Coulomb interactions and migrating Dirac cones in twisted graphene by local quantum oscillations
Matan Bocarsly, Indranil Roy, Vishal Bhardwaj +12
Flat band moiré graphene systems have emerged as a quintessential platform to investigate correlated phases of matter. A plethora of interaction-driven ground states have been prop…
Quantum Geometry and Stabilization of Fractional Chern Insulators Far from the Ideal Limit
Gal Shavit, Yuval Oreg
In the presence of strong electronic interactions, a partially filled Chern band may stabilize a fractional Chern insulator (FCI) state, the zero-field analog of the fractional qua…
