Reconfigurable chiral superconductivity
Surajit Dutta, Nadav Auerbach, Tonghang Han +9
Rhombohedral multilayer graphene at high displacement fields hosts superconductivity emerging from a spin valley polarized quarter metal, with transport signatures suggestive of ti…
Parametric Instabilities of Correlated Quantum Matter
Gal Shavit, Gil Refael
Collective bosonic excitations are a fascinating aspect of broken-symmetry correlated phases. A wealth of such phases emerged in tailored moiré heterostructures, where, in additio…
Nematic Enhancement of Superconductivity in Multilayer Graphene via Quantum Geometry
Gal Shavit
Multilayer graphene materials have recently emerged as a fascinating versatile platform for correlated electron phenomena, hosting superconductivity, fractional quantum Hall states…
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…
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…
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 superlatt…
